IndexError: tensors used as indices must be long, byte or bool tensors

[alexriedel1]

Describe the bug
When training PatchCore, I'm getting the following error:
IndexError: tensors used as indices must be long, byte or bool tensors
caused by the line

anomalib/anomalib/models/components/dimensionality_reduction/random_projection.py

Line 85 in c33d25a

components[i, c_idx] = data.double()

To Reproduce
Steps to reproduce the behavior:
Run the PatchCore algorithm on CPU (maybe on GPU too)

The problem can be solved by casting to c_idx to c_idx.long()

Could you please take a look into this issue? I've encountered this as well. I tried also PADIM, it worked but PatchCore failed with the above-mentioned error. Also please re-check other architecture.

Have you guys seen this issue when you train patchcore on GPU

I did a PR . I haven't tried to reproduce the issue on GPU
