Hmm, that is odd.  I have not been playing much with trying to register the ops myself because it sounded like they would have been registered just by doing “#include <torchvision/vision.h>”, which I have included in the .cpp file.  The way I had read to do that was to dump out a yaml file from python with your network’s ops specified in it, and then, when building pytorch, specifying that pre-made yaml file with “-DSELECTED_OP_LIST”, something like “-DSELECTED_OP_LIST:STRING=myNetOps.yaml”.  But again, I didn’t mess with that much since I read it wasn’t necessary unless you were trying to restrict things for space reasons or something…
I’m holding out hope that @tom will have some great insight on this.
