single-label rawframes annotation txt file

[robostoneDK]

Hi!

I have a question regarding the formatting of the annotation file.
Does the label number start with 0 or 1?

Say my label_map.txt looks like this
Playing
Studying

Should my label.txt file look like this (first approach)?
path/video1_frames 45 0
path/video2_frames 97 1
path/video3_frames 33 0
....

or like this(second approach?
path/video1_frames 45 1
path/video2_frames 97 2
path/video3_frames 33 1
....

When training the Timesfomer action recognrion, the first approach allows me to train, but my mean_acc ends up being 0.5
The second approach won't even let me train, as I get this error message:

/pytorch/aten/src/ATen/native/cuda/Loss.cu:247: nll_loss_forward_reduce_cuda_kernel_2d: block: [0,0,0], thread: [0,0,0] Assertion t >= 0 && t < n_classes failed.
