Error installing molsets due to dependency pomegranate==0.12.0

[dbhaskar92]

pip install molsets on Ubuntu 20.04.4 LTS with Python 3.8.13 and GCC 7.5.0 fails due to an error in installing a dependency.

Building wheel for pomegranate (setup.py) resulted in the following error:

building 'pomegranate.distributions.NeuralNetworkWrapper' extension

  ERROR: Failed building wheel for pomegranate

pip install pomegranate successfully installs pomegranate-0.14.8 on this machine. Has anyone else experienced this issue?

If anyone else stumbles upon this issue, it helps to:

1. Clone the repository to the desired location
2. Remove the version constraint for pomegranate in setup.py (as suggested in this PR)
3. Run python setup.py install

Using !pip install molsets==0.1.0 will solve the issue, as only the initial release has been removed of the pomegranate version constraint.

It worked for me!
