解决 from scipy._lib.decorator import decorator as _decorator出现ImportError: No module named decorator

问题描述：

from scipy._lib.decorator import decorator as _decorator
fairy@ubuntu:~/PycharmProjects/ANN/Density-Based-Clustering$ python LST.py
Traceback (most recent call last):
  File "LST.py", line 2, in <module>
    from scipy.spatial.distance import cdist
  File "/usr/lib/python2.7/dist-packages/scipy/spatial/__init__.py", line 94, in <module>
    from ._plotutils import *
  File "/usr/lib/python2.7/dist-packages/scipy/spatial/_plotutils.py", line 4, in <module>
    from scipy._lib.decorator import decorator as _decorator
ImportError: No module named decorator

思考及解决：是由于的decorator模块没有完全安装造成的，可先卸载后重装

 sudo apt install --reinstall python*-decorator
