ModuleNotFoundError: No module named 'pysam'

[maronem]

I have tried installing IsoQuant using both conda and manual installation but regardless of method I get the error ModuleNotFoundError: No module named 'pysam' when isoquant.py tries to import pysam.

(isoquant) Michaels-MacBook-Pro-3:IsoQuant michael$ ./isoquant.py --test
Traceback (most recent call last):
  File "/Users/michael/IsoQuant/./isoquant.py", line 22, in <module>
    import pysam
ModuleNotFoundError: No module named 'pysam'

I have tried setting up environments using multiple versions of python but have had no success. Here are the packages installed in my environment (which pysam is) with both minimap2 and samtools in my $PATH.

Any help would be much appreciated!

Dear @maronem

This is strange. What happens if you simply run python3 and run import pysam?
