In the middle of training as your instruction, I had some errors below.

File "/opt/anaconda3/envs/venv/lib/python3.7/site-packages/torch/utils/data/sampler.py", line 104, in init
"value, but got num_samples={}".format(self.num_samples))
ValueError: num_samples should be a positive integer value, but got num_samples=0

The issue is that the dataset path was not set correctly in the program. Make sure that you pass the correct argument for where you downloaded the dataset.
