Starting from v1.4.0 pypcd4 cannot be installed on aarch64

[mawerid]

Replace python-lzf with python-neo-lzf make the installation of the pypcd4 library using uv impossible.

The error:

Using CPython 3.10.19 interpreter at: /usr/local/bin/python3
Creating virtual environment at: .venv
Resolved 23 packages in 2.54s
error: Distribution `python-neo-lzf==0.3.2 @ registry+https://link/to/my/project/pypi` can't be installed because it doesn't have a source distribution or wheel for the current platform
hint: You're on Linux (`manylinux_2_36_aarch64`), but `python-neo-lzf` (v0.3.2) only has wheels for the following platforms: `manylinux_2_5_x86_64`, `manylinux_2_28_x86_64`, `manylinux1_x86_64`, `musllinux_1_2_x86_64`, `macosx_10_9_universal2`, `win32`, `win_amd64`; consider adding "sys_platform == 'linux' and platform_machine == 'aarch64'" to `tool.uv.required-environments` to ensure uv resolves to a version with compatible wheels

The root cause:

python-neo-lzf package have no wheels for aarch64.

Thank you for reporting this issue.

We have submitted a fix in PR #57 that switches the dependency to python-lzf on aarch64 environments.

Since we only have x64 machines available, we verified the fix using QEMU emulation, and the build completed successfully. Could you please test it in your native environment to confirm it works as expected?

[mawerid]

Thank you for so fast reply!

How I can test it in my env? I coundn't find the link to the artifact related to this PR

@mawerid
Since verified wheels (artifacts) have not been generated yet, you'll need to install directly from the Git branch.
To ensure your current environment remains clean, I recommend testing in a temporary virtual environment.

Please try the following steps:

# 1. Create a new virtual environment
uv venv .venv

# 2. Activate the virtual environment
source .venv/bin/activate

# 3. Install pypcd4 from the fix branch
uv pip install "git+https://github.com/MapIV/pypcd4.git@build/switch-lzf-on-arm64"

If this installs successfully without errors, the issue should be resolved. Please let me know the result!

[mawerid]

Now everything works fine

Thank you!

Will wait for the updates in master branch

@mawerid
Great, thank you for the confirmation!
We've merged the fix and released v1.4.1 on PyPI just now. You can now install the stable version directly:

uv pip install -U pypcd4

I reported the root of this problem to python-neo-lzf
