problem with backend
by Slavin, Jonathan May 8, 2024

May 8, 2024

Hi all, For some reason one of my environments has stopped working for plotting: python 3.11.3 ipython 8.22.2 matplotlib 3.8.4 When I start an ipython session with "ipython --pylab" it shows the backend as: Using matplotlib backend: <object object at 0x155522aebbc0> And if I try to plot, I just get a black window. Another environment that I have: python 3.11.0 ipython 8.9.0 matplotlib 3.6.3 works fine and shows: Using matplotlib backend: QtAgg when I do "ipython --pylab". Does anyone know what's causing this? The first environment I listed has been the one I've been using mostly and without any issues until recently. I think I updated something (via conda update), but I can't recall what at the moment.
