How can we use tqdm in a parallel execution with joblib?

Question

I want to run a function in parallel, and wait until all parallel nodes are done, using joblib. Like in the example:

from math import sqrt
from joblib import Par         


        

Answer 1

I've created pqdm a parallel tqdm wrapper with concurrent futures to comfortably get this done, give it a try!

To install

pip install pqdm

and use

from pqdm.processes import pqdm
# If you want threads instead:
# from pqdm.threads import pqdm

args = [1, 2, 3, 4, 5]
# args = range(1,6) would also work

def square(a):
    return a*a

result = pqdm(args, square, n_jobs=2)
