FSLeyes crashing

Describe the bug When I first installed ADS a few months ago, I remember trying out fsleyes and installing the plugin. Everything worked fine from what I recall. I volunteered to write some doc for the plugin (#473) but now I can’t open fsleyes anymore… I get the following error:

Traceback (most recent call last):
  File "/home/herman/.conda/envs/ads_venv/lib/python3.7/site-packages/fsl/utils/idle.py", line 576, in __idleLoop
    task.task(*task.args, **task.kwargs)

To Reproduce

$ conda activate ads_venv
$ fsleyes

Platform (please complete the following information):

• OS: Manjaro 21.0.7 Ornara (kernel: x86_64 Linux 5.10.35-1-rt39-MANJARO)
• AxonDeepSeg version number: 3.2.0 (master)

I am aware that there are issues installing fsleyes on Linux. I feel like I’m in a deadend right now because there doesn’t seem to be a pre-release wxPython build for my distro and getting it up and running looks like a potential nightmare. I’ll update this issue if I find anything useful.

is fsleyes really the GUI option we want to maintain? I know there were efforts to find a more stable software for ADS integration.

nope! 😊 see: #404

I was told fsleyes is still somewhat widely used, so maybe it is still a good approach.

it depends on the community. It is widely used by the MRI community and it is absolutely not used by the microscopy community. As @Stoyan-I-A said in https://github.com/neuropoly/axondeepseg/issues/544#issuecomment-889929672 we used FSLeyes because we know it, but it is not a good enough reason to keep it if it is not a good long term solution.

Ideally, no. I would prefer something with more compatibility across operating systems.

FSLeyes was used because it was fairly simple to integrate ADS on it as a plugin.
