10-isc: nilearn plotting error

[manojneuro]

We get a plotting error when running 10-isc.

Steps to replicate:

1. In the notebook set upper_limit_n_subjs = 5
2. Execute cells.
3. Error occurs in Section 2.3, in the cell before Exercise 3.

surf_map = plotting.plot_surf_stat_map(
    fsaverage.infl_left, texture, 
    hemi='left', view=view, 
    title= title_text, 
    threshold=threshold, cmap='RdYlBu_r', 
    colorbar=True,
    bg_map=fsaverage.sulc_left)

Error: NotImplementedError: It is not currently possible to manually set the aspect on 3D axes

What version of nilearn are you using on google collab ?

[ltetrel]

We are now using 0.5.2 version.
So it seems to be an issue with nilearn . A depreciationWarning coming after this release :

@manojneuro Can you confirm that the notebooks are running on google collab with nilearn 0.5.2 ?

@manojneuro any update?

[manojneuro]

@ltetrel on Colab the notebooks are running on 0.5.2. There seemed to have been an issue with this plotting function in nilearn in 0.5.1, that is fixed in 0.5.2. Could you double check if you have 0.5.2 installed?

@ltetrel An update on this issue. It seems to be a problem with matplotlib 3.1, see here: nipy/mindboggle#177

They recommend either waiting for the next nilearn release, or going back to an older version of matplotlib. I tested with matplotlib==3.0.3 and it works on Colab.

[ltetrel]

Interresting, maybe we should wait for the new nilearn release then

[manojneuro]

I'm not sure when the release will be out, we can always upgrade once the release is out.
