Environment Configuration Issues

[lazycat0]

Hello! After reading your article "Matrix Factorization-based Technique for Drug Repurposing Predictions," I used the following environment to run your code:

Python 3.7.16
scikit-learn 0.22
matplotlib 3.5.3
tqdm 4.66.1
scipy 1.7.3
numpy 1.21.6
pandas 1.3.5
seaborn 0.12.2
spherecluster 0.1.7

However, I encountered issues during the actual execution. Could it be due to environmental factors?

When I attempt to call skm1.fit(self.R12_train.transpose()), I always get the error message 'Expected sequence or array-like, got <class 'NoneType'>'.

Hi, thank for the interest in our project.

Sorry for the latency but I have been traveling.

Did you manage to resolve the problem or can I assist you with anything?
