Is the python part of ML agent supposed to be reinstalled everytime?

Hello. I’ve currently started learning about ml agents. I’ve successfully got everything running. The thing is whenever I turn off the project and reopen it, then insert the command mlagent-learn, it says the method cannot be found. So I have to download pytorch and ml from the command prompt again. Is this supposed to work like this or not?

I found the solution. You need to have the project opened at the sametime.
