Does the dnn module of opencv GPU is support on jetson platform? which version of opencv?
DNN module in OpenCV cannot be compiled with latest cuDNN v8.0 package due to API change.
You can build v4.3.0 from source with the following script on the JetPack4.4 DP (notice: latest GA version doesn’t work).
The JetPack 4.4 - L4T R32.4.3 production release Is GA?
Please use the JetPack that inlcudes L4T R32.4.2 for OpenCV DNN.
