ImportError: cannot import name 'IndexMixin'

Hi,

When I ran

import scanpy.api as sc

I met this error:

     19 from scipy import sparse
     20 from scipy.sparse import issparse
---> 21 from scipy.sparse.sputils import IndexMixin
     22 from natsort import natsorted
     23 

ImportError: cannot import name 'IndexMixin'

Is there any requirements for the version of scipy?

Thanks in advance, BP

Hi, I just tried install a higher version of scipy, and it works now.

pip install scipy==1.2.1

Refer to: https://www.scipy.org

I also ran into this issue when using scanpy==1.4.2 and scipy==1.3.0 (which are the versions installed when I install using conda). Enforcing scipy==1.2.1 in my conda environment file fixed it.
