Just try the old way, use python main.py INPUT_FILE.fasta OUTPUT_DIRECTORY, the omegafold INPUT_FILE.fasta OUTPUT_DIRECTORY only works if you python setup.py install first or use the pip install git+ command, sorry for the confusion, we are going to update that ASAP.

Thanks Rui - I have python 3 available on the system, but 2.75 is the default system python. Now that I realize the cause of the error, running as python3.8 -m pip install -r requirements.txt allows installation to proceed successfully. Thanks!
