Could not load the Qt platform plugin "xcb"

[space-beaver]

I'm using a compute cluster and have set up feems in conda using the second, longer, method. I had to change the version of one of the dependencies but otherwise everything was sucessful. When I work through the example notebook, when I enter the code:

fig = plt.figure(dpi=300)

I get the error:

`fig = plt.figure(dpi=300)
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.`

I can't seem to find a solve for this.

TIA

This seems to be a cluster-specific issue (and potentially a python wide issue too). I wonder if you can ask the sysadmins if they've seen an error like this before?
