update python version for the api wheel

[patrickwasp]

Summary

python 3.5.2 has reached end of life. Consider updating to 3.10+.

Use case

it's not straightforward to install old versions of python on ubuntu 22.04

Python 3.10+ compatibility would be greatly appreciated. Commenting to bump the issue.

Hi all,

Our documentation is not up to date (we are working on that), but I can confirm Python 3.11 works fine.

I will leave this issue open for now in case you encounter some issue migrating.

Cheers

Dear Kinova Team, I am still getting an AttributeError when using Python 3.10 but not 3.8 Error: "module 'collections' has no attribute 'MutableMapping'" when trying to import anything from kortex_api I'd like to avoid having to up/downgrade my Python version. Any other ideas?

[martinleroux]

This issue actually lies in the version of the protobuf package that is installed with Python 3.10 or higher. You can try installing the .whl file with the following commands:

pip install protobuf==3.20 deprecated==1.2.7 pip install "kortex_api-2.6.0.post3-py3-none-any.whl" --no-deps

A PR should comme some to clarify this in the documentation.

Thanks :)

I am not sure if this was resolved but adding the following lines before importing kortex_api solved it for me.

import sys
if sys.version_info.major == 3 and sys.version_info.minor >= 10:    # Change to == if it already works for 3.11
    import collections
    setattr(collections, "MutableMapping", collections.abc.MutableMapping)
    setattr(collections,"MutableSequence", collections.abc.MutableSequence)

#from kortex_api...

The attribute MutableMapping was moved to collections.abc in python 3.10

Just double checked. It does not seem to work with 3.11.4 as well. Same issue as mentioned previously. It may not be ideal to downgrade protobuf. If the documentation needs more time to update, I can create a PR with the above lines added to the python API examples.

P.S. this would be necessary for anyone using ROS2 Humble along with the Python API.
