Hello, I am looking for a solution to be able to instantiate an object that will exploit another heart of cpu all by manipulating it from another process.
Currently the only solution I found is to use pickle.
But :
1) But I find this solution low performing
2) I can not for example create a tkinter window in my object
This is my code, Would you have more optimal solutions to offer me ?
