@orena1 I have the same issue, have you solved it in some way ?

[gui-miotto]

Hi guys, from what I could understand this is a problem regarding cython and python 3.7. I could solve it by installing direct from source (I think that generates new C code with the latest cython).

In other words, do: 1 - Update cython (conda update cython) 2 - Follow these instructions 3 - Comment here and let people know whether it worked.

[mhhennig]

Same problems with pip install (same errors) here, linux, miniconda3, env with numpy etc. all set up. Installing from source worked.

[orena1]

@gui-miotto solution works

[GuillaumeGirier]

Hello,

I have Python 3.8 with Anaconda, and I have the same problem than in this topic. I did of course every steps that you adviced. (Maybe the error comes from the Python version?)

Can you help me, please?

Thank you.

[EdmundButler]

This appears to be due to a known incompatibility between numpy and cython versions. See numpy issue #17937 on github. You should not see it using the latest versions of numpy and cython. But, if you do, please report that with the numpy and cython versions.

Issue should be resolved (see latest comment by Ed).
