Instructions, EDA and baseline for Food Recognition Challenge

When trying to run the model for inference I get the error:

Traceback (most recent call last):
  File "mmdetection/tools/test.py", line 284, in <module>
    main()

    checkpoint = torch.load(filename, map_location=map_location)

From trying to load the weights.
I get the same error trying to use any other of the weights, besides the set ‘epoch_22.pth’
