AttributeError: module 'numpy' has no attribute 'int'.

[coolshreysh1000]

In the function viterbi from dthmm.pyx, on line 262 it is used

 cdef numpy.ndarray[int_t, ndim=2] psi = numpy.empty( (size,states_num), dtype=numpy.int )

Change it to

 cdef numpy.ndarray[int_t, ndim=2] psi = numpy.empty( (size,states_num), dtype=int )

Otherwise I am getting error

AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Same issue in line 288
Instead of cdef numpy.ndarray[int_t, ndim=1] path = numpy.full( size, 0, dtype=numpy.int )
Please use it as cdef numpy.ndarray[int_t, ndim=1] path = numpy.full( size, 0, dtype=int )

I had to redo Cython compiliation after making above changes and then my code is working correct
