Hi I got the same error as you! But I managed to resolve it by changing the following in the get_data(size, batch_size) function code block, in lines 8, 9 and 11 of that code block: change all the “data/train” and “data/val” and “data/test” to “data/content/data/train” and “data/content/data/val” and “data/content/data/test” respectively.
