It will be better to use to obtain a short period of PITCHf/x data by calling get_pitchfx directly unless you have supreme computation on your laptop, or you will spend nearly a whole day to scrape a season even as short as season 2020.
I will probably update two feautures in the future if I'm still interested in PITCHf/x.
- Multithreading (Boost the speed)
- Floating Proxy IP pools (Handle blocked-ip by excessive requesting)
You have an alternative to use google cloud platform and to rent a GPU if you want to get the data quickly.
