在Google Cloud Datalab中导入OpenCV

Question

How to import OpenCV in GCP? I'm using Google Datalab here.

It looks like I can install the package:

!pip install opencv-python

Collecting opencv-python

But after I import cv2, I get an error

import cv2

ImportErrorTraceback (most recent call last)

  8 sys.modules['cv2'] = cv2

ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
