Hi ! Can you double check that you uploaded your cache directory in the right location ? If it’s in the right location you offline machine will use this cache instead of throwing an error.
By default the location is ~/.cache/huggingface/datasets
But if you have uploaded your cache directory to somewhere else, you can try to specify your new cache directory with
raw_dataset = datasets.load_dataset('glue', 'sst2', cache_dir="path/to/.cache/huggingface/datasets")
