When I'm trying to download dataset,

I got warning /opt/conda/lib/python3.7/site-packages/pmaw/Request.py:263: UserWarning: 2000 items were not found in Pushshift
warnings.warn(f"{self.limit} items were not found in Pushshift")

and cannot download any images :(

Downloading comments of 0 submission files

How can I solve this problem?
