Hi Vito, This is a neat tool you've got here, I came across this error when I tried to use --max-dwn-cites

Environment: Google Colab

Input:

!python -m PyPaperBot --query="Machine learning" --scholar-pages=1  --min-year=2018 --max-dwn-cites=10 --dwn-dir="\content\papers" --scihub-mirror="https://sci-hub.do"

Output:

PyPaperBot is a Python tool for downloading scientific papers using Google Scholar, Crossref and SciHub.

Also when I tried to use --max-dwn-year

Input:

What's the reason for this🐺

Hi @Tolu1,

First of all thank you for your interest in PyPaperBot!
It's a silly naming error, I fix it in the day and release a new version.
I keep you updated.

[ferru97]

@Tolu1 now it should work, try it by downloading the new version v1.2.2

Hi @ferru97 thanks for your quick response, it appears your fix has broken something, I have created a new issue for that here #46
