Looking at the disc usage analyzer, it says that the modules for OpenCV are taking up 9GBs of memory? fatal error: can’t write PCH file: No space left on device How is that possible? I’m following these steps to reinstall opencv after wrestling with some issues for way too long … At the make -j4 …

Well, I don’t understand why it doesn’t work, but paste this URL: https://raw.githubusercontent.com/AastaNV/JEP/master/script/install_opencv4.5.0_Jetson.sh into your favorite web browser and you should see a bash script. Copy the full content and save to file install_opencv4.5.0_Jetson.sh, make it…

let me try that. thank you. will I need to remove the failed make files first to free up space?

Yes, cleanup the build directory so that you get some disk room again, and just use the install_opencv4.5.0_Jetson.sh from above for a new build.

hmmm … tried just doing a ./install_opencv4.5.0_Jetson.sh … and am getting an 'unexpected token ‘newline’ ’ error. I’ll step through the commands shortly and report back. EDIT: the script’s uninstall commands aren’t working. i’m assuming a purge command is fine?

Yes, the python install may not be correct. The following may not be a clean way to do that, but it works for me: # Note that enabling non_free opencv may lead to issues with python # Adjust python2 lib.. cd /usr/lib/python2.7/dist-packages/cv2/python-2.7 sudo mv -f cv2.so cv2.so.previous sudo ln…

well this is interesting … I don’t have a ‘cv2’ folder in the dist-packages folder for either version of python … Should I just create that folder and place the *.so files there? also, when moving the *.so files, how does the OS know where to find it? basically, the paths to the files are: /hom…

Hi, Please try to re-flash TX2 and run the script. In a clean system it should work by simply executing the script. Additional steps are not required. Would suggest try a clean system.

which script? can you please point me to the most up to date walkthrough that includes installing Remote Desktop and VNC (and the dependencies) as well as OpenCV? That would be helpful.
