The following values were not passed to accelerate launch and had defaults used instead: --num_processes was set to a value of 1 --num_machines was set to a value of 1 --mixed_precision was set to a value of 'no' --num_cpu_threads_per_process was set to 1 to improve out-of-box performance To avoid this warning pass in values for each of the problematic parameters or run accelerate config.

Same.

I fixed mine.

But your problem is this image:

PIL.UnidentifiedImageError: cannot identify image file '/content/data/sks/IMG_3819.HEIC'

That extension is the problem .HEIC delete it or convert to PNG.

This is related to #52. Please continue the discussion in that thread.
