I encountered the same problem. > To solve this issue it seems that you have to upgrade python3-matplotlib package at least to version 3.3 (the version packaged for ubuntu 20.10, I think)
v3.1.3 also supports pillow >= 7.0. This version might be more appropriate. https://github.com/matplotlib/matplotlib/releases/tag/v3.1.3 > - support pillow >= 7 Original fix. https://github.com/matplotlib/matplotlib/pull/16086 This fix is applied to v3.1.3 https://github.com/matplotlib/matplotlib/blob/v3.1.3/lib/matplotlib/backend_bases.py#L57 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897283 Title: Incompatibility with python3-pil v7.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/matplotlib/+bug/1897283/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
