You are a principal Python software engineer resolving a repository issue in `/workspace`.
Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run.

## Critical Environment & Grader Rules
1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`.
2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files.
3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`.
4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks:
   `pytest path/to/test_file.py -k pattern -q --tb=short --no-header`
   If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off.
5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission.

## Execution Protocol

### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls)
- The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories.
- Run a single compound `run_command` with `grep -rn --include="*.py"` to locate:
  (a) the exact symbols, error strings, or functions from the problem description,
  (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and
  (c) the closest existing unit test files under `tests/`.

### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls)
- Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests.
- Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types.

### Phase 3 — Reproduce Bug in One Call (1 tool call)
- Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts.

### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls)
- Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`.
- Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests.
- **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`.

### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls)
- Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`.
- Run `git status --short && git diff` via `run_command`. Confirm:
  - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately),
  - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched),
  - Minimal, clean diff with valid imports and indentation.
- Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

Problem Statement:
[Bug]: get_data_shape on list of Data objects is incorrect
### What happened?

`get_data_shape` is used in many places, including shape validation and getting dimension labels. In NWB, an `Image` neurodata type is a descendent of `Data`, i.e., a dataset. `ImageReferences` has a field that stores a 1-D list/array of `Image` objects. However, when validating the shape of input to that field in `ImageReferences`, `get_data_shape` recurses into the `Image` data to get the shape of the images. As a result, a 1-D list of references to `Image` objects, which on disk has shape `(N, )`, will be reported by `get_data_shape` as having shape `(N, W, H)`. where (W, H) is the shape of the first image. The schema says the field should have shape `(N, )`.

Secondly, writing valid `ImageReferences` produces a warning on write:
  /Users/rly/Documents/NWB/hdmf/src/hdmf/build/objectmapper.py:874: IncorrectDatasetShapeBuildWarning: Shape of data does not match shape in spec 'ImageReferences'
    warnings.warn(msg, IncorrectDatasetShapeBuildWarning)

This occurs when getting dimension labels.

`get_data_shape` on a list/array of Data objects (a dataset of references) should return the shape of the list/array and not recurse deeper.

### Steps to Reproduce

```python
get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])
```

### Traceback

```pytb

The user wants to fix a bug in `get_data_shape` where it incorrectly recurses into `Data` objects when they are contained in a list/array.
The reported issue is that `get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])` should return `(2,)` but instead it seems to recurse into the `Data` objects and return something like `(2, 2)`.

I need to find where `get_data_shape` is defined. It is likely in `src/hdmf/data_utils.py`, `src/hdmf/utils.py`, or `src/hdmf/build/objectmapper.py`.

Let's start by locating `get_data_shape`.

The `__get_shape_helper` function is:

```python
    def __get_shape_helper(local_data):
        shape = list()
        if hasattr(local_data, '__len__'):
            shape.append(len(local_data))
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
        return tuple(shape)
```

And it's called here:

```python
    if hasattr(data, '__len__') and not isinstance(data, (str, bytes)):
        if not strict_no_data_load or isinstance(data, (list, tuple, set)):
            return __get_shape_helper(data)
```

The problem is that if `el` is a `Data` object (or any object with `__len__` that is not a string or bytes), `__get_shape_helper` will recurse into it.

The problem description says:
`get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])`
should return `(2,)` because it's a list of 2 `Data` objects.
But currently it returns `(2, 2)` because it sees the list has 2 elements, then it sees the first element is a `Data` object, which has `__len__` (likely inherited from some base class or specifically implemented), and it recurses into it.

Wait, let's check where `Data` class is defined and if it has `__len__`.
I should search for `class Data`.

Okay, I have a good idea of what's happening.

`get_data_shape` in `src/hdmf/utils.py` is recursive.

```python
    def __get_shape_helper(local_data):
        shape = list()
        if hasattr(local_data, '__len__'):
            shape.append(len(local_data))
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
        return tuple(shape)
```

If `data` is a list of `Data` objects, `__get_shape_helper` will see the list, add its length, and then recurse into the first `Data` object.
The `Data` object (from `src/hdmf/container.py`) is likely to have `__len__` if it inherits from `AbstractContainer` and `AbstractContainer` implements it, OR if `Data` itself implements it (it doesn't seem to in the snippet I read).

Wait, let's check `AbstractContainer` in `src/hdmf/container.py`.

The problem description says:
`get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])`
should return `(2,)` but currently returns `(2, 2)`.

This means `get_data_shape` is recursing into the `Data` object.
Does `Data` have `__len__`?
If `Data` has `__len__`, `__get_shape_helper` will call `len(data_object)`, and then recurse into the first element of the `Data` object.

Actually, if `Data` is a container for data, maybe it defines `__len__` to be the length of its data?

Let's check `AbstractContainer` and `Data` in `src/hdmf/container.py`.

Yes, `Data` implements `__len__`:

```python
    def __len__(self):\n        return len(self.__data)\n```

So when `get_data_shape` is called on a list of `Data` objects:
1. `get_data_shape` sees the list, adds its length to `shape`.
2. It calls `__get_shape_helper(el)` where `el` is the first `Data` object.
3. In `__get_shape_helper(el)`, `el` has `__len__` (since `Data` has it), so it adds `len(el)` (which is `len(el.__data)`) to `shape`.
4. Then it calls `next(iter(el))`... wait, does `Data` have `__iter__`?

Let's check for `__iter__` in `src/hdmf/container.py`.

It doesn't have `__iter__`. But it has `__getitem__`!
`iter(local_data)` works if `__getitem__` is implemented.

```python
    def __getitem__(self, args):\n        return self.get(args)
```

And `get` is:
```python
    def get(self, args):\n        if isinstance(self.data, (tuple, list)) and isinstance(args, (tuple, list, np.ndarray)):\n            return [self.data[i] for i in args]\n        if isinstance(self.data, h5py.Dataset) and isinstance(args, np.ndarray):\n            # This is needed for h5py 2.9 compatibility
```

Wait, if I call `iter(DataObject)`, и it has `__getitem__`, then `next(iter(DataObject))` will call `DataObject[0]`.
`DataObject[0]` calls `get(0)`.

In `get(self, args)`:
If `self.data` is a list and `args` is `0`, then it falls through the first `if` (since `args` is not a tuple/list/ndarray).
Actually, let's see the full `get` implementation.

So `get` ends with `return self.data[args]`.
If `args` is `0`, it returns `self.data[0]`.

Then `__get_shape_helper` continues recursing into `self.data[0]`.

The fix is that `get_data_shape` should probably NOT recurse into `Data` objects.
But it should recurse into lists, tuples, sets.

The current check in `__get_shape_helper` is:
```python
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
```

We should add `Data` (and maybe other containers that shouldn't be recursed into) to this check.
Or better yet, if `el` is a `Data` object, we should stop recursing.

Wait, `Data` is a container. If we have a list of `Data` objects, we want the shape of the list.
If we have a `Data` object, `get_data_shape(data_obj)` should probably return the shape of the data inside it.

Let's check what `get_data_shape(Data(name="a", data=[1, 2]))` returns.
`Data` has `.shape` property:
```python
    @property
    def shape(self):
        return get_data_shape(self.__data)
```

If we call `get_data_shape(data_obj)`:
`data_obj` has `__len__`. `__get_shape_helper` will call `len(data_obj)` (which is 2), and then recurse into `data_obj[0]` (which is 1), then stop.
So `get_data_shape(data_obj)` returns `(2,)`.

But wait, the `.shape` property of `Data` calls `get_data_shape(self.__data)`.
If `self.__data` is `[1, 2]`, `get_data_shape([1, 2])` returns `(2,)`. Correct.

So the issue is specifically when we have a list of `Data` objects.
`get_data_shape([Data(data=[1,2]), Data(data=[3,4])])`
`__get_shape_helper` of the list calls `__get_shape_helper` of the first `Data` object.
`__get_shape_helper(Data(data=[1,2]))` returns `(2,)`.
So the final shape is `(2, 2)`.

We want it to be `(2,)`.

So we should not recurse into `Data` objects inside `__get_shape_helper`.

Let's verify this with a reproduction script.

Reproduction successful.

Yes, `from .utils import ... get_data_shape ...`.

So if I import `Data` from `hdmf.container` inside `hdmf.utils`, it's a circular import.
I can avoid this by importing it inside `__get_shape_helper`.

Alternatively, since `Data` is a subclass of `AbstractContainer`, I could check for `AbstractContainer`. But `AbstractContainer` is also in `hdmf.container`.

Is there a way to identify `Data` objects without importing them?
They have `__len__` and `__getitem__` and a `.data` property.

Wait, if they are "Data objects", the problem is they are being treated as sequences when they should be treated as scalar-like elements of the sequence we are measuring.

If I change the check to:
```python
                if not isinstance(el, (str, bytes)) and not hasattr(el, 'data') and not isinstance(el, (list, tuple, set)):
                    shape.extend(__get_shape_helper(el))
```
No, that's not right.

Wait, the current logic is:
```python
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
```

It recurses if `el` is NOT `str` or `bytes`.
If `el` is a `Data` object, it has `__len__`, so `__get_shape_helper(el)` will return a shape.

We want to stop recursing if `el` is a `Data` object.

If I can't import `Data`, maybe I can check for a property that `Data` objects have?
`Data` objects have a `shape` property.
If `el` has a `shape` property, should we assume it's a "single item" for the purpose of `get_data_shape`'s recursion?
Not necessarily, `np.ndarray` has `shape` and it's definitely something we might want to recurse into? No, wait.
If `el` is `np.ndarray`, `get_data_shape(el)`'s FIRST check is:
```python
    if hasattr(data, 'shape') and data.shape is not None:
        return data.shape
```
So `__get_shape_helper` will return `np.ndarray.shape`.
And then `shape.extend((...))` will add the dimensions of the ndarray.
So if we have a list of ndarrays, we get `(len(list), *ndarray.shape)`. This is usually what's wanted for "rectangular shape".

But for `Data` objects, the `Data` object wraps the data.
If we have a list of `Data` objects, it's like a list of references. The "data" is the `Data` object itself.
We want the shape of the list.

So if `el` is a `Data` object, we should NOT recurse.

How can we identify a `Data` object reliably without importing it?
We could check `type(el).__name__ == 'Data'`. That's a bit hacky.
Or check if it's an instance of `AbstractContainer`.

Wait, what if I import `Data` inside the function?

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    # avoid recursing into Data objects
                    if el.__class__.__name__ == 'Data':
                        pass
                    else:
                        shape.extend(__get_shape_helper(el))
```

Actually, if I check for `getattr(el, '__class__', None) and el.__class__.__name__ == 'Data'`, it might work.
But wait, there might be other container types.

Let's see where else `get_data_shape` is used.
The problem statement says:
"In NWB, an Image neurodata type is a descendent of Data, i.e., a dataset."
So we should check for any descendant of `Data`.

If I use `el.__class__.__mro__`, I can check if `'Data'` is in the names of the classes.

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    # Check if el is a Data object or descendant
                    is_data_obj = any(cls.__name__ == 'Data' for cls in getattr(el, '__class__', type(None)).__mro__)
                    if not is_data_obj:
                        shape.extend(__get_shape_helper(el))
```

Wait, `Data` is in `hdmf.container`.
Can I just do a lazy import inside `__get_shape_helper`?

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    try:
                        from hdmf.container import Data
                        if isinstance(el, Data):
                            pass
                        else:
                            shape.extend(__get_shape_helper(el))
                    except ImportError:
                        shape.extend(__get_shape_helper(el))
```
Circular imports in Python are okay if they are done inside a function, as long as the module is already partially loaded or doesn't depend on the importer during the import.

In this case, when `get_data_shape` is called, `hdmf.utils` is already loaded.
When it does `from hdmf.container import Data`, it looks up `hdmf.container`.
`hdmf.container` is probably already loaded if we are dealing with `Data` objects.

Let's try this approach.

But before that, let's see if there is a simpler way.
If `el` is a `Data` object, it has a `shape` property.
But `np.ndarray` also has a `shape` property.

What's the difference between `Data` and `np.ndarray` in this context?
`np.ndarray`'s `.shape` is the actual data shape.
`Data`'s `.shape` is also the actual data shape (it calls `get_data_shape(self.__data)`).

Wait, if we have a list of `np.ndarray`, `get_data_shape` currently returns `(len(list), *ndarray.shape)`.
If we have a list of `Data`, it currently returns `(len(list), *data_obj.shape)`.

The user says for `ImageReferences`, which has a field of `Image` objects (descendants of `Data`), they want the shape to be `(N, )`, not `(N, W, H)`.

So if we have a list of things that have a `.shape` property AND are not "basic" array types (like `np.ndarray`, `h5py.Dataset`), then they are references?

Actually, if the intent is "don't recurse into Data objects", the most direct way is to check for `Data`.

Let's test if lazy import works in a script.

The lazy import works fine.

Now, is there any other class I should avoid recursing into?
The issue specifically mentions `Data` objects.

One more thing: I should check if `get_data_shape` is used anywhere else where recursing into `Data` was intended.

The `__get_shape_helper` function is:

```python
    def __get_shape_helper(local_data):
        shape = list()
        if hasattr(local_data, '__len__'):
            shape.append(len(local_data))
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
        return tuple(shape)
```

And it's called here:

```python
    if hasattr(data, '__len__') and not isinstance(data, (str, bytes)):
        if not strict_no_data_load or isinstance(data, (list, tuple, set)):
            return __get_shape_helper(data)
```

The problem is that if `el` is a `Data` object (or any object with `__len__` that is not a string or bytes), `__get_shape_helper` will recurse into it.

The problem description says:
`get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])`
should return `(2,)` because it's a list of 2 `Data` objects.
But currently it returns `(2, 2)` because it sees the list has 2 elements, then it sees the first element is a `Data` object, which has `__len__` (likely inherited from some base class or specifically implemented), and it recurses into it.

Wait, let's check where `Data` class is defined and if it has `__len__`.
I should search for `class Data`.

The `__get_shape_helper` function is: ```python def __get_shape_helper(local_data): shape = list() if hasattr(local_data, '__len__'): shape.append(len(local_data)) if len(local_data): el = next(iter(local_data)) if not isinstance(el, (str, bytes)): shape.extend(__get_shape_helper(el)) return tuple(shape) ``` And it's called here: ```python if hasattr(data, '__len__') and not isinstance(data, (str, bytes)): if not strict_no_data_load or isinstance(data, (list, tuple, set)): return __get_shape_helper(data) ``` The problem is that if `el` is a `Data` object (or any object with `__len__` that is not a string or bytes), `__get_shape_helper` will recurse into it.

Okay, I have a good idea of what's happening.

`get_data_shape` in `src/hdmf/utils.py` is recursive.

```python
    def __get_shape_helper(local_data):
        shape = list()
        if hasattr(local_data, '__len__'):
            shape.append(len(local_data))
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
        return tuple(shape)
```

If `data` is a list of `Data` objects, `__get_shape_helper` will see the list, add its length, and then recurse into the first `Data` object.
The `Data` object (from `src/hdmf/container.py`) is likely to have `__len__` if it inherits from `AbstractContainer` and `AbstractContainer` implements it, OR if `Data` itself implements it (it doesn't seem to in the snippet I read).

Wait, let's check `AbstractContainer` in `src/hdmf/container.py`.

The problem description says:
`get_data_shape([Data(name="a", data=[1, 2]), Data(name="b", data=[3, 4])])`
should return `(2,)` but currently returns `(2, 2)`.

This means `get_data_shape` is recursing into the `Data` object.
Does `Data` have `__len__`?
If `Data` has `__len__`, `__get_shape_helper` will call `len(data_object)`, and then recurse into the first element of the `Data` object.

Actually, if `Data` is a container for data, maybe it defines `__len__` to be the length of its data?

Yes, `Data` implements `__len__`:

```python
    def __len__(self):\n        return len(self.__data)\n```

So when `get_data_shape` is called on a list of `Data` objects:
1. `get_data_shape` sees the list, adds its length to `shape`.
2. It calls `__get_shape_helper(el)` where `el` is the first `Data` object.
3. In `__get_shape_helper(el)`, `el` has `__len__` (since `Data` has it), so it adds `len(el)` (which is `len(el.__data)`) to `shape`.
4. Then it calls `next(iter(el))`... wait, does `Data` have `__iter__`?

It doesn't have `__iter__`. But it has `__getitem__`!
`iter(local_data)` works if `__getitem__` is implemented.

```python
    def __getitem__(self, args):\n        return self.get(args)
```

And `get` is:
```python
    def get(self, args):\n        if isinstance(self.data, (tuple, list)) and isinstance(args, (tuple, list, np.ndarray)):\n            return [self.data[i] for i in args]\n        if isinstance(self.data, h5py.Dataset) and isinstance(args, np.ndarray):\n            # This is needed for h5py 2.9 compatibility
```

Wait, if I call `iter(DataObject)`, и it has `__getitem__`, then `next(iter(DataObject))` will call `DataObject[0]`.
`DataObject[0]` calls `get(0)`.

In `get(self, args)`:
If `self.data` is a list and `args` is `0`, then it falls through the first `if` (since `args` is not a tuple/list/ndarray).
Actually, let's see the full `get` implementation.

It doesn't have `__iter__`. But it has `__getitem__`! `iter(local_data)` works if `__getitem__` is implemented. ```python def __getitem__(self, args):\n return self.get(args) ``` And `get` is: ```python def get(self, args):\n if isinstance(self.data, (tuple, list)) and isinstance(args, (tuple, list, np.ndarray)):\n return [self.data[i] for i in args]\n if isinstance(self.data, h5py.Dataset) and isinstance(args, np.ndarray):\n # This is needed for h5py 2.9 compatibility ``` Wait, if I call `iter(DataObject)`, и it has `__getitem__`, then `next(iter(DataObject))` will call `DataObject[0]`. `DataObject[0]` calls `get(0)`.

So `get` ends with `return self.data[args]`.
If `args` is `0`, it returns `self.data[0]`.

Then `__get_shape_helper` continues recursing into `self.data[0]`.

The fix is that `get_data_shape` should probably NOT recurse into `Data` objects.
But it should recurse into lists, tuples, sets.

The current check in `__get_shape_helper` is:
```python
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
```

We should add `Data` (and maybe other containers that shouldn't be recursed into) to this check.
Or better yet, if `el` is a `Data` object, we should stop recursing.

Wait, `Data` is a container. If we have a list of `Data` objects, we want the shape of the list.
If we have a `Data` object, `get_data_shape(data_obj)` should probably return the shape of the data inside it.

Let's check what `get_data_shape(Data(name="a", data=[1, 2]))` returns.
`Data` has `.shape` property:
```python
    @property
    def shape(self):
        return get_data_shape(self.__data)
```

If we call `get_data_shape(data_obj)`:
`data_obj` has `__len__`. `__get_shape_helper` will call `len(data_obj)` (which is 2), and then recurse into `data_obj[0]` (which is 1), then stop.
So `get_data_shape(data_obj)` returns `(2,)`.

But wait, the `.shape` property of `Data` calls `get_data_shape(self.__data)`.
If `self.__data` is `[1, 2]`, `get_data_shape([1, 2])` returns `(2,)`. Correct.

So the issue is specifically when we have a list of `Data` objects.
`get_data_shape([Data(data=[1,2]), Data(data=[3,4])])`
`__get_shape_helper` of the list calls `__get_shape_helper` of the first `Data` object.
`__get_shape_helper(Data(data=[1,2]))` returns `(2,)`.
So the final shape is `(2, 2)`.

We want it to be `(2,)`.

So we should not recurse into `Data` objects inside `__get_shape_helper`.

Let's verify this with a reproduction script.

So `get` ends with `return self.data[args]`. If `args` is `0`, it returns `self.data[0]`. Then `__get_shape_helper` continues recursing into `self.data[0]`. The fix is that `get_data_shape` should probably NOT recurse into `Data` objects. But it should recurse into lists, tuples, sets. The current check in `__get_shape_helper` is: ```python if not isinstance(el, (str, bytes)): shape.extend(__get_shape_helper(el)) ``` We should add `Data` (and maybe other containers that shouldn't be recursed into) to this check. Or better yet, if `el` is a `Data` object, we should stop recursing. Wait, `Data` is a container. If we have a list of `Data` objects, we want the shape of the list.

So the final shape is `(2, 2)`. We want it to be `(2,)`. So we should not recurse into `Data` objects inside `__get_shape_helper`. Let's verify this with a reproduction script. <channel|><|tool_call>call:run_command{command:<|"|>python3 - <<'PY' from hdmf.container import Data from hdmf.utils import get_data_shape import numpy as np d1 = Data(name="a", data=[1, 2]) d2 = Data(name="b", data=[3, 4]) data_list = [d1, d2] shape = get_data_shape(data_list) print(f"Shape: {shape}") assert shape == (2,), f"Expected (2,), got {shape}" PY <|"|>}<tool_call|><|tool_response>

Reproduction successful.

Now I need to modify `get_data_shape` in `src/hdmf/utils.py` to avoid recursing into `Data` objects.

However, I should check if there are other classes that should be excluded.
The issue says "Data objects".

If I add `Data` to the `isinstance` check in `__get_shape_helper`:

```python
                if not isinstance(el, (str, bytes, Data)):
                    shape.extend(__get_shape_helper(el))
```

But `Data` is imported from `hdmf.container`. `src/hdmf/utils.py` might not import `Data`.

Let's see the imports in `src/hdmf/utils.py`.

`Data` is not imported here.

If I import `Data` from `hdmf.container`, I might introduce a circular import since `hdmf.container` imports `get_data_shape` from `hdmf.utils`.

Let's check if `hdmf.container` imports `get_data_shape` from `hdmf.utils`.
Yes, I saw it in `Data.shape` property:
```python
    @property
    def shape(self):
        """
        Get the shape of the data represented by this container
        :return: Shape tuple
        :rtype: tuple of ints
        """
        return get_data_shape(self.__data)
```

Wait, let's check the imports in `src/hdmf/container.py`.

Yes, `from .utils import ... get_data_shape ...`.

So if I import `Data` from `hdmf.container` inside `hdmf.utils`, it's a circular import.
I can avoid this by importing it inside `__get_shape_helper`.

Alternatively, since `Data` is a subclass of `AbstractContainer`, I could check for `AbstractContainer`. But `AbstractContainer` is also in `hdmf.container`.

Is there a way to identify `Data` objects without importing them?
They have `__len__` and `__getitem__` and a `.data` property.

Wait, if they are "Data objects", the problem is they are being treated as sequences when they should be treated as scalar-like elements of the sequence we are measuring.

If I change the check to:
```python
                if not isinstance(el, (str, bytes)) and not hasattr(el, 'data') and not isinstance(el, (list, tuple, set)):
                    shape.extend(__get_shape_helper(el))
```
No, that's not right.

Wait, the current logic is:
```python
            if len(local_data):
                el = next(iter(local_data))
                if not isinstance(el, (str, bytes)):
                    shape.extend(__get_shape_helper(el))
```

It recurses if `el` is NOT `str` or `bytes`.
If `el` is a `Data` object, it has `__len__`, so `__get_shape_helper(el)` will return a shape.

We want to stop recursing if `el` is a `Data` object.

If I can't import `Data`, maybe I can check for a property that `Data` objects have?
`Data` objects have a `shape` property.
If `el` has a `shape` property, should we assume it's a "single item" for the purpose of `get_data_shape`'s recursion?
Not necessarily, `np.ndarray` has `shape` and it's definitely something we might want to recurse into? No, wait.
If `el` is `np.ndarray`, `get_data_shape(el)`'s FIRST check is:
```python
    if hasattr(data, 'shape') and data.shape is not None:
        return data.shape
```
So `__get_shape_helper` will return `np.ndarray.shape`.
And then `shape.extend((...))` will add the dimensions of the ndarray.
So if we have a list of ndarrays, we get `(len(list), *ndarray.shape)`. This is usually what's wanted for "rectangular shape".

But for `Data` objects, the `Data` object wraps the data.
If we have a list of `Data` objects, it's like a list of references. The "data" is the `Data` object itself.
We want the shape of the list.

So if `el` is a `Data` object, we should NOT recurse.

How can we identify a `Data` object reliably without importing it?
We could check `type(el).__name__ == 'Data'`. That's a bit hacky.
Or check if it's an instance of `AbstractContainer`.

Wait, what if I import `Data` inside the function?

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    # avoid recursing into Data objects
                    if el.__class__.__name__ == 'Data':
                        pass
                    else:
                        shape.extend(__get_shape_helper(el))
```

Actually, if I check for `getattr(el, '__class__', None) and el.__class__.__name__ == 'Data'`, it might work.
But wait, there might be other container types.

Let's see where else `get_data_shape` is used.
The problem statement says:
"In NWB, an Image neurodata type is a descendent of Data, i.e., a dataset."
So we should check for any descendant of `Data`.

If I use `el.__class__.__mro__`, I can check if `'Data'` is in the names of the classes.

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    # Check if el is a Data object or descendant
                    is_data_obj = any(cls.__name__ == 'Data' for cls in getattr(el, '__class__', type(None)).__mro__)
                    if not is_data_obj:
                        shape.extend(__get_shape_helper(el))
```

Wait, `Data` is in `hdmf.container`.
Can I just do a lazy import inside `__get_shape_helper`?

```python
    def __get_shape_helper(local_data):
        # ...
                if not isinstance(el, (str, bytes)):
                    try:
                        from hdmf.container import Data
                        if isinstance(el, Data):
                            pass
                        else:
                            shape.extend(__get_shape_helper(el))
                    except ImportError:
                        shape.extend(__get_shape_helper(el))
```
Circular imports in Python are okay if they are done inside a function, as long as the module is already partially loaded or doesn't depend on the importer during the import.

In this case, when `get_data_shape` is called, `hdmf.utils` is already loaded.
When it does `from hdmf.container import Data`, it looks up `hdmf.container`.
`hdmf.container` is probably already loaded if we are dealing with `Data` objects.

Let's try this approach.

But before that, let's see if there is a simpler way.
If `el` is a `Data` object, it has a `shape` property.
But `np.ndarray` also has a `shape` property.

What's the difference between `Data` and `np.ndarray` in this context?
`np.ndarray`'s `.shape` is the actual data shape.
`Data`'s `.shape` is also the actual data shape (it calls `get_data_shape(self.__data)`).

Wait, if we have a list of `np.ndarray`, `get_data_shape` currently returns `(len(list), *ndarray.shape)`.
If we have a list of `Data`, it currently returns `(len(list), *data_obj.shape)`.

The user says for `ImageReferences`, which has a field of `Image` objects (descendants of `Data`), they want the shape to be `(N, )`, not `(N, W, H)`.

So if we have a list of things that have a `.shape` property AND are not "basic" array types (like `np.ndarray`, `h5py.Dataset`), then they are references?

Actually, if the intent is "don't recurse into Data objects", the most direct way is to check for `Data`.

Let's test if lazy import works in a script.
