Hi Andrey, There are at least three Python packages with the name snappy:
1. snappy 3.0.1 (https://pypi.org/project/snappy/): This can be install as pip install snappy, and the command installs the following packages: FXrays-1.3.5 cypari-2.4.1 decorator-4.4.2 future-0.18.2 knot-floer-homology-1.0.2 plink-2.4 pypng-0.0.20 snappy-3.0.1 snappy-manifolds-1.1.2 spherogram-2.0. 2. snappy-manifolds 1.1.2 ( https://pypi.org/project/snappy-manifolds/#history) -- pip install snappy-manifolds: This one is part of the snappy package above. 3. python-snappy 0.6.0 (https://pypi.org/project/python-snappy/) -- pip install python-snappy: This is the one that other packages which use it complain it has no attribute compress. I installed all these packages one by one and tested the codes with Python 3.9.6 (and also with Ipython 7.16.1) under Ubuntu-Linux 18.04 and did not notice any conflicts or an error in question. Maybe later upgrade from python 3.9.2 to a higher version or uninstalling and reinstalling the snappy and python-snappy packages can solve the problem.
