Python opencv Aruco "No module named 'cv2.aruco'"
If cv2.aruco
is not found, first make sure that opencv-python
is not installed.
for that you can use:
pip uninstall opencv-python
Then install:
pip install opencv-contrib-python
We are uninstalling opencv-python because installing two packages of opencv will contradict each other and will not let the other one install.
If cv2.aruco
is not found, try installing opencv-contrib-python
, such as by running the following (for the default Python installation):
pip install opencv-contrib-python
Or for a specific Python installation (in this case Python 3)
python3 -m pip install opencv-contrib-python
Then try re-running the script trying to access cv2.aruco
.
In my case both opencv-python
and opencv-contrib-python
were installed when I was getting the above error.
So I uninstalled opencv-python using
pip uninstall opencv-python
Run the program and same error. Then I uninstalled opencv-contrib-python
pip uninstall opencv-contrib-python
After that I reinstalled opencv-contrib-python using
pip install opencv-contrib-python
And run the program, no error now. So I upvoted both the above answers :)
