Looping Issue

[adamtrobbins]

Zooming in a plot and then playing the simulation does not seem to work. To reproduce the bug, one can do the following:

1. Start Iseult in '/scratch/gpfs/ar3676/9_test_sigma_0.3_r/output'
2. Zoom in on the upper-right plot (using the Zoom to rectangle feature)
3. Hit 'Play'

I get the following errors:

You need to load earlier anaconda, before 2023.9. Add "module load anaconda3/2023.9" to .bashrc and restart the shell (relogin or source ~/.bashrc)

Or you can use conda environment as explained on Iseult readme page.

This is correct. Iseult was written using some matplotlib protected members and matplotlib has changed the format and internal usage of those members as of v3.8. I haven't figured out a good way around that yet so for now we're locked to a specific version of matplotlib; see Issue #15 for some more details.

You can either use the anaconda module that @ntoles mentioned or, the recommended method, use the latest Anaconda module available and create an environment for Iseult using the environment.yml in the repository root directory. Instructions are in the Readme and more details are in the environment.yml file. Using the environment will let you use the latest version of all the other packages that work with the required version of Matplotlib.
