Hi I'm trying to use score mode on the main.py with a video1.mp4 example I placed in a videos directory inside the project directory but i get at the end this error:
./videos/: Is a directory
Traceback (most recent call last):
File "main.py", line 57, in
result = classify_video('tmp', input_file, class_names, model, opt)
File "/home/nuno/PycharmProjects/video-classification-3d-cnn-pytorch/classify.py", line 31, in classify_video
video_outputs = torch.cat(video_outputs)
RuntimeError: expected a non-empty list of Tensors
here is the full terminal log:
python3 main.py --input ./input --video_root ./videos --output ./output.json --model ./resnet-34-kinetics.pth --mode feature
