how shall I calculate "predict" by hand after "GaussianHMM.fit() " instead of "predict()"?

I do as below: hmm=GaussianHMM(n_components=5,covariance_type='diag',n_iter=500).fit(X) Now I want to predict 'x';and I know I can do it by code: hmm.predict(x); but shall I see the some parameters of "hmm" and calculate it by hand ? The simple…
