Error with hsp.py step with tutorial data

[sjackrel]

Hi, I am trying to run the tutorial data and am getting stuck at the second command. I've tried within and without the -e parameter. Command and error below.

Sara

hsp.py -i 16S -t out.tre -o marker_predicted_and_nsti.tsv.gz -p 1 -n -e float 0

Traceback (most recent call last):

Hi there,

This seems like an incompatibility with python 3.6 and the contextlib package for some reason -- see this issue too: https://stackoverflow.com/questions/69520829/openai-gym-attributeerror-module-contextlib-has-no-attribute-nullcontext

Is the problem resolved if you install a higher Python version?

Yes, thank you!
