I am running an Ubuntu virtual machine with, Python 3.6.1, Anaconda 4.4.0 (64-bit). I am trying to run the code on this website. When I try to use
import cv2.aruco
I get:
>>> import cv2.aruco
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cv2.aruco'
Is this something I need to install or setup?
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
.
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.
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 :)
