Installation issue with pixy

[vinod1981]

Hi, Just installed pixy with python3.8 and everything worked well but when testing it, it is causing error:

pixy --version
Traceback (most recent call last):
  File "/vol/cluster-data/vkumar/miniconda3/envs/pixy_pop/bin/pixy", line 7, in <module>
    from pixy.__main__ import main

ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use '<void>numpy._import_array' to disable if you are certain you don't need it).

Tried various versions of numpy but can't solve the issue. Thanks

I ran into a similar issue recently, I posted my fix as an issue here: https://github.com/ksamuk/pixy/issues/94

Installing numpy=1.21 and samtools=1.9 after installing pixy worked for me.

I believe this should now be solved in the newest release, please update with conda install --yes -c conda-forge pixy and let me know if you still have this issue. Thanks for reporting!
