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]: Error on parsing nwb_version attribute
### What happened?
I'm in the process of updating our CI pipeline to validate the IPNWB/MIES generated NWB.
pynwb is updated from 2.1.0 to 2.3.1.
The file passes validation.
See also https://github.com/AllenInstitute/MIES/pull/1650.
Now the problem is that the file can not be opened anymore because `/nwb_version` has an unexpected HDF5 format. This was not an issue with 2.1.0. a1f472b1 (Check nwb_version on read (#1612), 2022-12-18) seems to be culprit.
```
HDF5 "E:\projekte\mies-igor\HardwareBasic_1-V2.nwb" {
ATTRIBUTE "nwb_version" {
DATATYPE H5T_STRING {
STRSIZE 5;
STRPAD H5T_STR_NULLPAD;
CSET H5T_CSET_UTF8;
CTYPE H5T_C_S1;
}
DATASPACE SCALAR
DATA {

}
}
}
```
### Steps to Reproduce
```python
import pynwb
io = pynwb.NWBHDF5IO("HardwareBasic_1-V2.nwb", 'r', load_namespaces=True)
nwbfile = io.read()
```
### Traceback
```python

## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns
## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.
## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.

The user is reporting a `TypeError: a bytes-like object is required, not 'str'` in `pynwb/__init__.py` when calling `io.read()`.
The traceback points to:
```python
File "C:\users\thomas\Anaconda3\lib\site-packages\pynwb\__init__.py", line 280, in read
file_version_str, file_version = self.nwb_version
File "C:\users\thomas\Anaconda3\lib\site-packages\pynwb\__init__.py", line 262, in nwb_version
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
TypeError: a bytes-like object is required, not 'str'
```
Wait, the error `TypeError: a bytes-like object is required, not 'str'` usually happens when you try to call a string method on a bytes object, or vice versa, but specifically when a function expects bytes and gets a string, or when you call a bytes method on a string.
Wait, look at the line:
`nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")`
If `nwb_version_string` is a `bytes` object, calling `.replace("-", ".")` (where `"-"` and `"."` are strings) will raise a `TypeError: a bytes-like object is required, not 'str'`.
So `nwb_version_string` is likely a `bytes` object, and the code is trying to use string methods on it with string arguments.
Let's locate the code in `/workspace/src/pynwb/__init__.py`.
First, I'll grep for `nwb_version` in `src/pynwb/__init__.py`.

The `nwb_version` is a property.
```python

def nwb_version(self):
# ...

nwb_version_string = self._file.attrs['nwb_version']

```
In h5py, attributes can sometimes be returned as bytes instead of strings, depending on how they were written and the h5py version. The problem description says:
```
ATTRIBUTE "nwb_version" {
DATATYPE H5T_STRING {
STRSIZE 5;
STRPAD H5T_STR_NULLPAD;
CSET H5T_CSET_UTF8;

```
If `nwb_version_string` is `bytes` (e.g., `b'2.2.4'`), then `nwb_version_string.replace("-", ".")` will raise `TypeError: a bytes-like object is required, not 'str'`.
I should ensure `nwb_version_string` is a string before performing the replacements.
Let's verify this behavior with a reproduction script. I'll need a dummy HDF5 file with a `nwb_version` attribute as bytes.

It seems `pynwb` is having trouble finding the namespaces. The error `RuntimeError: 'core' is not a registered namespace` suggests that the schema namespaces are not correctly loaded. The workspace layout shows `src/pynwb/nwb-schema`. Wait, I should check how `pynwb` is installed in the environment. I'll try to run the reproduction a bit differently. Since I'm working on the source code, maybe I should set `PYTHONPATH` to `src`. Also, the `nwb_version` property in `NWBHDF5IO` is quite simple and doesn't seem to depend on the namespaces being registered, it just accesses `self._file.attrs['nwb_version']`. But `NWBHDF5IO` initialization might be where the failure occurs. Let's check `src/pynwb/__init__.py` to see the `NWBHDF5IO` class.

It seems `__resources['namespace_path']` does not exist. Let's see how `__get_resources()` is defined.

Ah, it uses `pkg_resources.resource_filename(__name__, 'nwb-schema/core')`. This depends on the package being installed as a package. When running from source, `__name__` is `pynwb` and `pkg_resources` might not find the resources if the current directory is not in the path or if the package isn't installed in editable mode.
I should use `PYTHONPATH=src` and maybe mock how it finds resources, or just use `NWBHDF5IO` from a context where it doesn't trigger that global check if possible. But `import pynwb` always triggers it.
Alternatively, I can just bypass the issue by using a simpler test that doesn't require the full `NWBHDF5IO` but just uses a mock object for the file attributes.
Actually, the bug is very simple: `nwb_version_string` can be `bytes`, and we need to handle that.
Let's see:
```python
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
If `nwb_version_string` is `bytes`, we can decode it.
```python
if isinstance(nwb_version_string, bytes):
nwb_version_string = nwb_version_string.decode('utf-8')
```
Wait, what if it's not `bytes` but something else? The traceback says `TypeError: a bytes-like object is required, not 'str'`, which happens when you call `.replace("-", ".")` on `bytes`.
Wait, actually:
If `x` is `bytes`, `x.replace(b'-', b'.')` works. `x.replace('-', '.')` fails with `TypeError: a bytes-like object is required, not 'str'`.
So if `nwb_version_string` is `bytes`, the current code `nwb_version_string.replace("-", ".")` fails.
I'll try to reproduce it without importing the whole `pynwb` if it's causing issues with namespaces, or I'll set `PYTHONPATH` and see if I can fix the `RuntimeError`.
Actually, if I just want to test the `nwb_version` property, I can mock the `NWBHDF5IO` object.
Wait, `NWBHDF5IO` is a class in `src/pynwb/__init__.py`. I can just import the class if I fix the namespace issue.
Let's try setting `PYTHONPATH=src` and see if that fixes the `RuntimeError`.
Wait, the `RuntimeError` is:
`'core' is not a registered namespace. If you installed PyNWB locally using a git clone, you need to use the --recurse_submodules flag when cloning.`
And the code is:
```python
__resources = __get_resources()
if os.path.exists(__resources['namespace_path']):
load_namespaces(__resources['namespace_path'])
else:
raise RuntimeError(...)
```
`__get_resources()`:
```python
def __get_resources():
from pkg_resources import resource_filename
ret = dict()
ret['namespace_path'] = os.path.join(resource_filename(__name__, 'nwb-schema/core'), __core_ns_file_name)
return ret
```
If I'm running from `src`, `__name__` will be `pynwb`. `resource_filename('pynwb', 'nwb-schema/core')` should work if `src` is in `PYTHONPATH`.
Let's try:

Okay, it seems `pkg_resources` is not working as expected for the core namespace when running from source. I can try to find where `nwb-schema/core` is and mock `__resources`. Looking at the workspace: `./src/pynwb/nwb-schema` Let's see what's inside `src/pynwb/nwb-schema`.

Wait, the workspace layout said:
`./src/pynwb/nwb-schema`
But it's empty. This explains the `RuntimeError`. It seems the schema is missing.
However, I don't need the schema to reproduce this bug. I just need to test the `nwb_version` property.
I can just mock the `NWBHDF5IO` object and its `_file` attribute.
The `nwb_version` property:
```python
@property
def nwb_version(self):
# ...
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
nwb_version = tuple([int(i) if i.isnumeric() else i
for i in nwb_version_parts])
return nwb_version_string, nwb_version
```
I can just create a simple class that has a `_file` attribute with an `attrs` dictionary.
Wait, `NWBHDF5IO` is defined in `src/pynwb/__init__.py`. If I import it, the module-level code runs and fails.
I can read the code and implement the logic in a separate script to verify it.

The reproduction is successful. `nwb_version_string.replace("-", ".")` fails when `nwb_version_string` is `bytes`.
Now I need to fix it. The fix is to ensure `nwb_version_string` is a string.
I can do:
```python
if isinstance(nwb_version_string, bytes):
nwb_version_string = nwb_version_string.decode('utf-8')
```
Let's see where to put this in `src/pynwb/__init__.py`.
```python
@property
def nwb_version(self):
# ...
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
I should put it right after `nwb_version_string = self._file.attrs['nwb_version']`.
Wait, if I decode it to a string, then `nwb_version_string` will be a string, and `.replace()` will work.
Let's check if there are any other places where `nwb_version` is handled.
In `src/pynwb/io/utils.py`:
```python
def get_nwb_version(builder: Builder, include_prerelease=False) -> Tuple[int, ...]:
# ...
nwb_version = root_builder.attributes.get("nwb_version")
if nwb_version is None:
raise ValueError("'nwb_version' attribute is missing from the root of the NWB file.")
if nwb_version == "2.0b":
# ...
# This might also fail if nwb_version is bytes
nwb_version_match = re.match(r"(\d+\.\d+\.\d+)", nwb_version)[0]
```
If `nwb_version` is `bytes`, `re.match(r"(\d+\.\d+\.\d+)", nwb_version)` might fail or return a match object with bytes, but `re.match` with a string pattern on bytes will raise `TypeError: cannot use a string pattern on a bytes-like object`.
Wait, let's check `src/pynwb/io/utils.py`.

Yes, `get_nwb_version` in `src/pynwb/io/utils.py` also has the same problem.
```python
nwb_version = root_builder.attributes.get("nwb_version")
if nwb_version is None:
raise ValueError("'nwb_version' attribute is missing from the root of the NWB file.")
# handle special non-semver case
if nwb_version == "2.0b":
```
If `nwb_version` is `bytes`, `nwb_version == "2.0b"` will be `False` (since `b'2.0b' != '2.0b'`). Then `re.match(r"(\d+\.\d+\.\d+)", nwb_version)` will raise `TypeError`.
So I should also fix `src/pynwb/io/utils.py`.
Let's check if there are other places.
I'll search for `nwb_version` again to be sure.

The `icephys.py` ones seem to be just passing `nwb_version` as an argument to a print statement, so they should be fine.
Now let's apply the fix to `src/pynwb/__init__.py`.
```python
@property
def nwb_version(self):
# ...
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
if isinstance(nwb_version_string, bytes):
nwb_version_string = nwb_version_string.decode('utf-8')
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
And to `src/pynwb/io/utils.py`:
```python
nwb_version = root_builder.attributes.get("nwb_version")
if nwb_version is None:
raise ValueError("'nwb_version' attribute is missing from the root of the NWB file.")
if isinstance(nwb_version, bytes):
nwb_version = nwb_version.decode('utf-8')
# handle special non-semver case
if nwb_version == "2.0b":
```
Wait, in `src/pynwb/__init__.py`, `nwb_version_string` is returned at the end:
`return nwb_version_string, nwb_version`
If I decode it, I've changed the return value from `bytes` to `str`. Is that okay?
The original code was:
```python
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
Which crashed if it was `bytes`. So it assumed it was `str` (or at least something that had `.replace` with `str` arguments).
If it was `bytes`, and we return it as `str`, that's generally what's expected.

Wait, the error `TypeError: a bytes-like object is required, not 'str'` usually happens when you try to call a string method on a bytes object, or vice versa, but specifically when a function expects bytes and gets a string, or when you call a bytes method on a string.
Wait, look at the line:
`nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")`
If `nwb_version_string` is a `bytes` object, calling `.replace("-", ".")` (where `"-"` and `"."` are strings) will raise a `TypeError: a bytes-like object is required, not 'str'`.
So `nwb_version_string` is likely a `bytes` object, and the code is trying to use string methods on it with string arguments.

In h5py, attributes can sometimes be returned as bytes instead of strings, depending on how they were written and the h5py version. The problem description says:

It seems `pynwb` is having trouble finding the namespaces. The error `RuntimeError: 'core' is not a registered namespace` suggests that the schema namespaces are not correctly loaded. The workspace layout shows `src/pynwb/nwb-schema`. Wait, I should check how `pynwb` is installed in the environment. I'll try to run the reproduction a bit differently. Since I'm working on the source code, maybe I should set `PYTHONPATH` to `src`. Also, the `nwb_version` property in `NWBHDF5IO` is quite simple and doesn't seem to depend on the namespaces being registered, it just accesses `self._file.attrs['nwb_version']`. But `NWBHDF5IO` initialization might be where the failure occurs. Let's check `src/pynwb/__init__.py` to see the `NWBHDF5IO` class.

Ah, it uses `pkg_resources.resource_filename(__name__, 'nwb-schema/core')`. This depends on the package being installed as a package. When running from source, `__name__` is `pynwb` and `pkg_resources` might not find the resources if the current directory is not in the path or if the package isn't installed in editable mode.
I should use `PYTHONPATH=src` and maybe mock how it finds resources, or just use `NWBHDF5IO` from a context where it doesn't trigger that global check if possible. But `import pynwb` always triggers it.
Alternatively, I can just bypass the issue by using a simpler test that doesn't require the full `NWBHDF5IO` but just uses a mock object for the file attributes.
Actually, the bug is very simple: `nwb_version_string` can be `bytes`, and we need to handle that.
Let's see:
```python
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
If `nwb_version_string` is `bytes`, we can decode it.
```python
if isinstance(nwb_version_string, bytes):
nwb_version_string = nwb_version_string.decode('utf-8')
```
Wait, what if it's not `bytes` but something else? The traceback says `TypeError: a bytes-like object is required, not 'str'`, which happens when you call `.replace("-", ".")` on `bytes`.
Wait, actually:
If `x` is `bytes`, `x.replace(b'-', b'.')` works. `x.replace('-', '.')` fails with `TypeError: a bytes-like object is required, not 'str'`.
So if `nwb_version_string` is `bytes`, the current code `nwb_version_string.replace("-", ".")` fails.
I'll try to reproduce it without importing the whole `pynwb` if it's causing issues with namespaces, or I'll set `PYTHONPATH` and see if I can fix the `RuntimeError`.
Actually, if I just want to test the `nwb_version` property, I can mock the `NWBHDF5IO` object.
Wait, `NWBHDF5IO` is a class in `src/pynwb/__init__.py`. I can just import the class if I fix the namespace issue.
Let's try setting `PYTHONPATH=src` and see if that fixes the `RuntimeError`.
Wait, the `RuntimeError` is:
`'core' is not a registered namespace. If you installed PyNWB locally using a git clone, you need to use the --recurse_submodules flag when cloning.`
And the code is:
```python
__resources = __get_resources()
if os.path.exists(__resources['namespace_path']):

else:

```
`__get_resources()`:

ret = dict()
ret['namespace_path'] = os.path.join(resource_filename(__name__, 'nwb-schema/core'), __core_ns_file_name)
return ret

Wait, the workspace layout said:
`./src/pynwb/nwb-schema`
But it's empty. This explains the `RuntimeError`. It seems the schema is missing.
However, I don't need the schema to reproduce this bug. I just need to test the `nwb_version` property.
I can just mock the `NWBHDF5IO` object and its `_file` attribute.
The `nwb_version` property:
```python
@property
def nwb_version(self):
# ...
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
nwb_version = tuple([int(i) if i.isnumeric() else i
for i in nwb_version_parts])
return nwb_version_string, nwb_version
```
I can just create a simple class that has a `_file` attribute with an `attrs` dictionary.
Wait, `NWBHDF5IO` is defined in `src/pynwb/__init__.py`. If I import it, the module-level code runs and fails.
I can read the code and implement the logic in a separate script to verify it.

The reproduction is successful. `nwb_version_string.replace("-", ".")` fails when `nwb_version_string` is `bytes`.
Now I need to fix it. The fix is to ensure `nwb_version_string` is a string.
I can do:
```python
if isinstance(nwb_version_string, bytes):
nwb_version_string = nwb_version_string.decode('utf-8')
```
Let's see where to put this in `src/pynwb/__init__.py`.
```python
@property
def nwb_version(self):
# ...
try:
nwb_version_string = self._file.attrs['nwb_version']
except KeyError:
return None, None
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
I should put it right after `nwb_version_string = self._file.attrs['nwb_version']`.
Wait, if I decode it to a string, then `nwb_version_string` will be a string, and `.replace()` will work.
Let's check if there are any other places where `nwb_version` is handled.
In `src/pynwb/io/utils.py`:
```python
def get_nwb_version(builder: Builder, include_prerelease=False) -> Tuple[int, ...]:
# ...
nwb_version = root_builder.attributes.get("nwb_version")
if nwb_version is None:
raise ValueError("'nwb_version' attribute is missing from the root of the NWB file.")
if nwb_version == "2.0b":
# ...
# This might also fail if nwb_version is bytes
nwb_version_match = re.match(r"(\d+\.\d+\.\d+)", nwb_version)[0]
```
If `nwb_version` is `bytes`, `re.match(r"(\d+\.\d+\.\d+)", nwb_version)` might fail or return a match object with bytes, but `re.match` with a string pattern on bytes will raise `TypeError: cannot use a string pattern on a bytes-like object`.

Yes, `get_nwb_version` in `src/pynwb/io/utils.py` also has the same problem.

The `icephys.py` ones seem to be just passing `nwb_version` as an argument to a print statement, so they should be fine.
Now let's apply the fix to `src/pynwb/__init__.py`.
```python
@property

nwb_version_string = self._file.attrs['nwb_version']

nwb_version_string = nwb_version_string.decode('utf-8')
# Parse the version string
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
And to `src/pynwb/io/utils.py`:
```python
nwb_version = root_builder.attributes.get("nwb_version")
if nwb_version is None:
raise ValueError("'nwb_version' attribute is missing from the root of the NWB file.")

Wait, in `src/pynwb/__init__.py`, `nwb_version_string` is returned at the end:
`return nwb_version_string, nwb_version`
If I decode it, I've changed the return value from `bytes` to `str`. Is that okay?
The original code was:
```python
nwb_version_parts = nwb_version_string.replace("-", ".").replace("_", ".").split(".")
```
Which crashed if it was `bytes`. So it assumed it was `str` (or at least something that had `.replace` with `str` arguments).
If it was `bytes`, and we return it as `str`, that's generally what's expected.
