install.sh contains pycuda installation.

I am having problem running the script, I am getting this error:

PyCUDA ERROR: The context stack was not empty upon module cleanup.

A context was still active when the context stack was being
cleaned up. At this point in our execution, CUDA may already
have been deinitialized, so there is no way we can finish
cleanly. The program will be aborted now.
Use Context.pop() to avoid this problem.

I think you didn’t create a trt model by referring to the install requirements

I did all the steps with military precision, on multiple attempts on freshly installed jetpack 4.51 and jetpack 4.5 with no success running the usb cam python script. It is simply not working, I wonder if anyone here had any success with it? Can you do it in a docker container?

I run install.sh and I still get the same error

Same thing, I have done the installation twice, following every step and it does not work

ผมใช้วิธีนี้ แล้วมันสามารถแก้ปัญหาได้ Install PyCUDA on Jetson Nano - Dropout Analytics - Medium

It works for me! Thank you, JardinRyu.

By running the program, I got an error stating “ModuleNotFoundError: No module named 'pycuda”
but I got through this referring to

sudo pip3 install --global-option=build_ext --global-option="-I/usr/local/cuda/include" --global-option="-L/usr/local/cuda/lib64" pycuda
