Cannot import Voronoi from scipy.spatial

[jeertmans]

Hello,

I'm trying to import Voronoi from scipy.spatial but it does not work, see the error message.

My environment.yml:

name: xeus-python-kernel  
channels:  
- https://repo.mamba.pm/emscripten-forge  
- https://repo.mamba.pm/conda-forge  
dependencies:  
- ipympl  
- matplotlib>=3,<4  
- numpy>=1.24,<1.25  
- scipy==1.8.1

and SciPy is correctly installed from your channel:

scipy              emscripten-forge/emscripten-32::scipy-1.8.1-py310h74ff0a5_4

I have tried clearing the cache, but this does not solve the issue.

I took a quick look at https://github.com/emscripten-forge/recipes/tree/main/recipes/recipes_emscripten/scipy, and it does not seem that Voronoi was removed from SciPy.

Locally, when scipy==1.8.1 on Python 3.10, I can import it with success:

Python 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from scipy.spatial import Voronoi
>>> import scipy;scipy.__version__
'1.8.1'

NOTE: I am using JupyterLite, and the corresponding repository can be found here.

Likely related to #619

Any idea how to solve this? @michaelweinold

#619 does not seem to point to a solution

[michaelweinold]

As per @martinRenou‘s comment, the only way to resolve the issue would be a version upgrade of matplotlib and scipy. Unfortunately, both pull requests (linked in the discussion of #619) have test failures at the moment.

Thanks!

[DerThorsten]

should be fixed with #643

Thanks @DerThorsten ! Will try this out when I have some time :-)
