[pymanopt] ImportError: cannot import name 'comb' from 'scipy.misc'

[lkorczowski]

While the following error seems to be fixed months ago, whatever I do, I still have the error with my numpy-1.18.1 pymanopt-0.2.4 scipy-1.4.1 (force-reinstalled).

when

from pymanopt.manifolds import Grassmann

Traceback (most recent call last):

ImportError: cannot import name 'comb' from 'scipy.misc' (/Users/louis/anaconda3/envs/timeflux_rasr-env/lib/python3.7/site-packages/scipy/misc/__init__.py)

fix :
in pymanopt/manifolds/rotation.py change L10 to
from scipy.special import comb (instead of from scipy.misc)

The weirdest part: it has been fixed pymanopt/pymanopt#77

And my pymanopt is updated.

If you experience this error, please let me know by doing the following:
from pymanopt.manifolds import Grassmann

Thanks

Also: it's been a while I'm using pymanopt and I got this error just today :/, what could have modified my pymanopt ? (I did merge master in the pymanopt branch and this error happened for the first time when I was using pytest)
