title: How can we use tqdm in a parallel execution with joblib?
body: <p>I want to run a function in parallel, and wait until all parallel nodes are done, using joblib. Like in the example:</p>
  
  <pre><code>from math import sqrt
  from joblib import Parallel, delayed
  Parallel(n_jobs=2)(delayed(sqrt)(i ** 2) for i in range(10))
  </code></pre>
  
  <p>But, I want that the execution will be seen in a single progressbar like with <strong>tqdm</strong>, showing how many jobs has been completed. </p>
  
  <p>How would you do that?</p>
