transform_grayscale not implementet for class(x)

[Slimnshady]

Hey there,

I was wondering if I'm doing anything wrong, or if the transform_grayscale functionality is actually not implemented for any class?

Backtrace: ▆

1. ├─torchvision::transform_grayscale(img = img, num_output_channels = 3)
2. └─torchvision:::transform_grayscale.default(img = img, num_output_channels = 3)
3. └─torchvision:::not_implemented_for_class(img)

4. └─torchvision:::not_implemented_error(paste0("not implemented for ", class(x)))
   

Run rlang::last_trace(drop = FALSE) to see 1 hidden frame.

Hi, can you please provide a reproducible example? Thanks!
