Error matplotlib.colormaps

[nicolas-langlade]

Hi MCScanX developer and users,
I am having an error with matplotlib.colormaps (see below)
When I am not using mpl it works such as with the following command

python3 -m jcvi.compara.synteny depth --histogram HanXRQr2.HanIR.anchors
So I think my files are fine and it's really a problem with the package version

Do you have any idea how to fix it? Did you have it?
Thanks for your help
Nicolas

python3 -m jcvi.graphics.dotplot HanXRQr2.HanIR.anchors

This may be due to an older version of matplotlib. Could you do a pip install -U matplotlib to install a more recent version?

Please let me know if the problem persists after upgrade.

Hi,
Thanks for your reply, this was something related to my installation and that I could solve creating a new environment etc...
I am very happy with the package, the visual output and my results ;)
Thanks again
