python hmmlearn中的导入错误

Question

I am trying to install python hmmlearn library to build continuous HMM. I have installed all the dependencies and the hmmlearn library from GitHub. The installation completes successfully.

...
Processing dependencies for hmmlearn==0.2.1
Searching for scikit-learn==0.18.1
Best match: scikit-learn 0.18.1
Adding scikit-learn 0.18.1 to easy-install.pth file
Using /usr/local/lib/python2.7/dist-packages
Finished processing dependencies for hmmlearn==0.2.1

But in python, when I try to import GaussianHMM using

from hmmlearn.hmm import GaussianHMM

it gives some import error:

 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "hmmlearn/hmm.py", line 22, in <module>
 from .base import _BaseHMM
 File "hmmlearn/base.py", line 13, in <module>
 from . import _hmmc
 ImportError: cannot import name _hmmc

The problem is in hmmlearn/setup.py which doesn't list utils as a submodule.

Add this line to setup.py config.add_subpackage("utils")
