Problem with CUDA and OpenCV

Post by xeryax » Sat Mar 21, 2020 7:43 pm

So, i am having some trouble with trying to use CUDA/HWacceleration for events...
I've downloaded the latest CUDA, staged the .deb packages in the opencv foler, and run opencv.sh numerous times

I think detection is still running on my CPU, as it is dog slow, and while it isnt the best test in the world, i keep running nvidia-smi to see if any processes are using the GPU, and nothing ever does when events fire...

when i run nvidia-smi on the container before running opencv.sh, i get the following output (note cuda version:

Code: Select all

When i run it after i run the opencv.sh i get the same thing EXCEPT that "CUDA Version: N/A"

What step of the instructions am i clearly missing? I ask it that way because im almost 100% positive i had this working before, but cant get it there now.

also, a few side notes on the container, i can put these elsewhere if you want...

would be awesome if you got rid of these options in apache2/sites-enabled/default-ssl.conf, it causes a prompt for cert every time i open a new browser.
SSLVerifyClient optional_no_ca
SSLVerifyDepth 10

and several folders in /config default to needing chmod +x on them -- no biggie unless you are like me and doing samba sharing for docker management.

Thanks for this container, you've done a lot of good work, and I am very grateful.
