SuRVoS crashes when attempting to press the pensil button

[DimitriosBellos]

Hi, I recently installed SuRVoS and I attemtped to segment some data, however when I pressed the pensil (Draw ground truth seeds) button (this button is in the Slice Viewer tab) SuRVoS crashed Specifically I got the following

  File "/home/psxdb3/anaconda3/envs/survos-env/lib/python3.6/site-packages/survos/widgets/slice_viewer.py", line 61, in gt
    if self._active == 'GT':
AttributeError: 'NavigationToolbar' object has no attribute '_active'

I don't know what is the issue. But I also get some empty/blank buttons in the Slice Viewer that if I press them SuRVoS also crashes with the same prompt.

Hi @DimitriosBellos Sorry to hear that, you're the second person to report it (see #107 ). Perhaps something has changed with pyQt I'll look into it and get back to you. Are you using Windows or Linux?

I run it on our servers in Nottingham and they have Linux, CentOS to be exact

Also here is a screenshot with the blank buttons I mentioned

Hi again @DimitriosBellos As a temporary fix can you down grade matplotlib by using conda install matplotlib-base==3.2.2 in the conda environment that you created for SuRVoS. It appears that something in matplotlib 3.3.2 is breaking things. I'll look into a more permanent fix.
