Deprecated Scikit-learn module prevents joblib from loading it
After reverting to scikit-learn 0.16.x, I just needed to install OpenBlas for Ubuntu. It appears that the problem was more a feature of the operating system rather than Python.
I have a Hidden Markov Model that has been pickled with joblib using the sklearn.hmm module. Apparently, in version 0.17.x this module has been deprecated and moved to hmmlearn. I am unable to load the model and I get the following error:

ImportError: No module named 'sklearn.hmm'

I have tried to revert back to version 0.16.x but still cannot load the model. I get the following error:

ImportError: libopenblas.so.0: cannot open shared object file: No such file or directory

I do not have access to the source code to recreate the model and re-pickle it
I am running Python 3.5
Has anyone else experienced this problem and have you found a solution? Does anyone know if scikit-learn has any way to guarantee persistence since the deprecation?
