so do i use "pip install -r requirements.txt" before or after i do the pip freeze?? and do i have to do them both? or why not?

[shirsendudhar]

In Pycharm, do I have to always download the same libraries before doing different projects, or one a library is installed I can again use it without downloading it again?

May I ask some questions? What if we only have a python file from other people's code but there is no requirements.txt, how do I install all packages required for specific python file all at once?

when I do pip freeze > requriments.txt it also gave some of the unused package name which I didn't used in my program and also when I tried to deploy my program in Heroku cloud, even heroku was not able to install all the requriment which was there in requriments.txt file. Please help me on creating proper requriments.txt

I used pip freeze > requriments.txt in pycharm
