GUI crashes when trying to annotate

[zhoutunhe]

Hi,
I'm following instruction in this video: https://www.jove.com/v/56162/volume-segmentation-analysis-biological-materials-using-survos-super

Everytime when I was at annotation step, SuRVos crashes when I clicked the pen button, the errror message is here:

create_supervoxels

• Loading data into memory
• Computing supervoxels
  [GPU] Reusing device (0) with 1024 threads

I'm on windows 10, with SurVos installed from Annaconda following the installation instruction here https://diamondlightsource.github.io/SuRVoS/docs/installation/

Thank you very much for help in advance!

Cheers
Tun

Hi Tun,

Sorry about this, I don't know of a fix for this issue, and @OllyK who normally takes a look at this kind of thing is on leave at the moment. I will try to replicate the problem and get back to you.

Hi again @zhoutunhe

If youhave access to the SuRVoS installation, as a temporary fix can you downgrade 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.

Thank you very much! It works now with your suggestion.
