ImportError:没有名为'cv2'Python3的模块

Question

我有这样的问题

(face_det) user@pc:~$ python3
Python 3.5.3 (default, Apr 22 2017, 00:00:00) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'cv2

我在python2上没有它:

(face_det) user@pc:~$ python2
Python 2.7.13 |Anaconda custom (64-bit)| (default, Dec 20 2016, 23:09:15) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

尽管如此,我有opencv(我还尝试删除它然后安装):

(face_det) user@pc:~$ pip3 install opencv
Requirement already satisfied: opencv in ./.virtualenvs/face_det/lib/python3.5/site-packages
(face_det) user@pc:~$ conda install opencv
