所以我已经从Ubuntu 14.04上成功地从源代码安装了OpenCV 3.2.0 ，并且出现此错误：

(cv2) mona@pascal:~/computer_vision/opencv-3.2.0/build$ /usr/local/bin/opencv_version

3.2.0

(cv2) mona@pascal:~/computer_vision/opencv-3.2.0/build$ python

Python 3.4.3 (default, Nov 17 2016, 01:08:31)

[GCC 4.8.4] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import cv2

Traceback (most recent call last):

File "", line 1, in

ImportError: No module named 'cv2'

>>> import cv

Traceback (most recent call last):

File "", line 1, in

ImportError: No module named 'cv'

我可能会错过的sudo make install步骤之后该怎么办？

不幸的是，这里也没有cv2：
