Multiprocessing working in Python but not in iPython

Question

I am running the following code in iPython:

import multiprocessing

def my_function(x):
    \"\"\"The function you want to compute in parallel.\"\"\"
    x +         


        

Answer 1

From the documentation:

Note

Functionality within this package requires that the __main__ module be importable by the children. This is covered in Programming guidelines however it is worth pointing out here. This means that some examples, such as the multiprocessing.Pool examples will not work in the interactive interpreter
