until kushalkolar/mesmerize-viz#42 install pygfx and fpl from specific commits: pip install git+https://github.com/pygfx/pygfx.git@2927712faeb867412a233b3efc8743ba1cc4cb11
pip install "fastplotlib[notebook] @ git+https://github.com/fastplotlib/fastplotlib.git@418a73b2aef82043af004f392faf6b4d2c577deb" note that the min required python version is 3.10 |
I followed the instruction above to install within mescore environment and restart the computer but I still have the same issue, thank you! |
and my python version is Python 3.10.8 |
I just released a pypi package for mesviz which gives you the versions of |
