ImportError: No Module Named 'cv2' Python3
Solution 1:
Try
pip3 install opencv-python
to get the cv2
. I'm not sure when opencv-python
became available. I'd been building opencv by hand, but when I looked a few weeks ago, there it was. I'm using cv2
with Python3 in a VM that's running ubuntu/trusty64
.
Solution 2:
Try
sudo python3.5 -m pip install opencv-python
It worked for me
Solution 3:
Your conda openCV is installed for use by your home python2.7. Your opencv installed via pip3 is for use in your face_det virtual environment. It doesn't look like you're in that virtual environment when you opened python3 in the first code block. Try
source activate face_det
python3
import cv2
Solution 4:
I think you're on Linux judging by pc:~$
Try installing from the following link:
http://docs.opencv.org/3.0-beta/doc/tutorials/introduction/linux_install/linux_install.html
It worked for me, hope the same for you!
Solution 5:
I had a similar problem and the same error. In my case, I was using PyCharm. The problem was that the project's interpreter was pointing to a different installation of Python.
In my system, I had four versions of python (eg. python3 installed in a python36
folder, another python in an anaconda3
folder and others). In my PyCharm project, when I examined my settings (under File->Settings->Project:xxxx ->Project interpreter), I found that they were pointing to the interpreter in the anaconda3
folder.
However, my default pip
installed the opencv-python
module under the python36
folder. Therefore, I just had to change the project interpreter to point to the python installed in python36
folder and it worked.
If you would like to keep using Anaconda3 then you have to browse to the anaconda3
folder and run pip install opencv-python
in that folder.
