Hi @thibaut-d ! Thank you for writing up this issue. We really appreciate that you give us all the system info up front.

As you see at the bottom of the zivid-python Readme we only officially support Ubuntu 18.04 and 20.04 (https://github.com/zivid/zivid-python#test-matrix), so unfortunately we don't have coverage for 21.10 in the CI system. Once 22.04 is out we will add official support for that. However, I am confident that it should be possible to get this working on Ubuntu 21.10, and I will do a little investigation to see how it can be done.

In the meantime can you verify for me whether or not the Zivid Studio desktop application works on your system?

Hi again! I just tested setting all this up in a clean Ubuntu 21.10 Docker container, and zivid-python installation + import zivid all worked fine. However, I used python 3.9 since that is the default python3 on Ubuntu 21.10. Can you try with python 3.9?

[thibaut-d]

Thanks, I tested too with Anaconda Python 3.8 and 3.9, this does not change the issue.

[thibaut-d]

Is there some other logs I can provide ?

[thibaut-d]

I got it running using the system version of Python instead of Anaconda:

conda deactivate myenv
pip3 install zivid

Not very clean but it solve the issue.

[eskaur]

Good, then we know it works with the system Python at least.

We don't specifically support the Anaconda setup, so you are a bit on your own there, but I'm sure there is a way to make that work as well. I have one idea: Try uninstalling Zivid SDK and re-install using the 18.04 debs instead of the 20.04 debs. These will expect a different GLIBCXX version, and perhaps it will be the one that your Anaconda has.

Another idea: Update to a newer gcc for building zivid-python.

Also, if you are merely uncomfortable installing directly on the system python, you could always make a normal non-Anaconda venv, python3 -m venv ./myvenv, and install zivid-python in there.
