module 'cv2' has no attribute 'sfm' #3746

Open cultist123 opened 4 months ago

cultist123 commented 4 months ago

I have installed all the necessary dependencies according to https://docs.opencv.org/4.x/db/db8/tutorial_sfm_installation.html and successfully compiled and installed them. However, when I run import cv2; help(cv2.sfm) in the terminal, it keeps showing module 'cv2' has no attribute 'sfm'. Similarly, when trying other modules like 'face', it also outputs something like module 'cv2' has no attribute 'face'. I suspect it's an issue with the site-package, so I changed the Python path to point to the site-package directory. I'm not sure if what I did is correct. Below are the outputs from my cmake and Python3.

import cv2 help(cv2.sfm) Traceback (most recent call last): File "", line 1, in AttributeError: module 'cv2' has no attribute 'sfm'

opencv-alalek commented 4 months ago

Your local build doesn't include Python binding. In your environment import cv2 uses something else (check through cv2.__file__ and getBuildInformation()).

Build / usage questions should go to Users OpenCV Q/A forum: https://forum.opencv.org/

Check OpenCV Extra Modules: Ensure that you have the opencv_contrib repository cloned and properly configured. The extra modules like sfm and face are part of the opencv_contrib modules.

Set Up CMake: When configuring OpenCV with CMake, ensure you include the path to the opencv_contrib modules. Here’s an example command to configure OpenCV with the extra modules:

cd /path/to/opencv/build cmake -DOPENCV_EXTRA_MODULES_PATH=/path/to/opencv_contrib/modules ..

Rebuild OpenCV: After configuring CMake, rebuild and install OpenCV:

make -j8 # adjust -j8 to the number of cores in your CPU

sudo make install Verify Installation: Ensure that the installation paths are correctly set up and that Python is using the correct OpenCV package. You can verify this by checking the installation directory:

python3 -c "import cv2; print(cv2.file)" This should point to your newly built OpenCV installation.

Python Path Configuration: Ensure that your Python environment is using the correct OpenCV site-package. Sometimes, multiple installations can cause conflicts. Update your PYTHONPATH to include the correct directory:

export PYTHONPATH=/usr/local/lib/python3.10/site-packages:$PYTHONPATH Check Installed Modules: You can list the installed modules in the OpenCV package to ensure that sfm and face are included:

python3 -c "import cv2; print(dir(cv2))"
