MLE ValueError

[dizuml]

Hi,
i love using this library but everytime i try to use the (discrete) maximum_likelihood_estimation i end up with this Error:

dhmm1.maximum_likelihood_estimation(S1, K1)
File "hmms\dthmm.pyx", line 353, in hmms.dthmm.DtHMM.maximum_likelihood_estimation
File "hmms\dthmm.pyx", line 379, in hmms.dthmm.DtHMM.maximum_likelihood_estimation
ValueError: Buffer dtype mismatch, expected 'int_t' but got 'long long'

even your example Code does not work for me.
Changing the dtype of the input Arrays to int32 didn't help.
I use Pycharm on Windows, maybe it's a Kernel thing.

Do you have any idea?
thx
