If I change python to c++ can I train a neural network? faster?

Question

Python

There is a ready-made self-written neural network in python 3. The problem is that in the neural network I use a loop to recalculate epochs. There is an 8-core processor, and python executes the entire cycle on one processor core (The problem of multithreading in python). Is it possible to parallelize calculations across cores in C++? To speed up epoch calculations.

Answer 1

What is the problem with multithreading in Python?
there are modules threading, subprocess, multiprocessing
multithreading in python

Answer 2

do it on the video card.
there are libraries that can use the capabilities of the GPU.
programming language is not important.
if you want to personally program everything and it is on the central processor - yes, C ++ will be significantly faster than Python.
