python - python hmmlearn中的导入错误

Question

我正在尝试安装 python hmmlearn 库来构建连续的 HMM。我已经从 GitHub 安装了所有依赖项和 hmmlearn 库。安装成功完成。

...
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

但是在 python 中，当我尝试使用导入 GaussianHMM

from hmmlearn.hmm import GaussianHMM

它给出了一些导入错误：

 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

Answer 1

问题出在 hmmlearn/setup.py 中，它没有将 utils 列为子模块。

将此行添加到 setup.pyconfig.add_subpackage("utils")
