# The output has unnormalized scores. To get probabilities, you can run a sigmoid on it.
probs = torch.sigmoid(output[0]) # Tensor of shape 6000, with confidence scores over Danbooru's top 6000 tags

inds = probs.argsort(descending=True)

Here is what the above code is Doing:
1. We’re using the model to get the output for the image.
2. We’re using the sigmoid function to get the confidence scores for each tag.
3. We’re setting a threshold value and using it to get the tags with confidence scores above the threshold.
4. We’re sorting the tags in descending order of confidence scores.
