warning persisting input arguments

[amueller]

I got

UserWarning: Persisting input arguments took 0.66s to run.
If this happens often in your code, it can cause performance problems 
(results will be correct in all cases). 
The reason for this is probably some large input arguments for a wrapped
 function (e.g. large strings).
THIS IS A JOBLIB ISSUE. If you can, kindly provide the joblib's team with an
 example so that they can fix the problem.

The example is a pandas dataframe containing the telco customer churn data: https://www.kaggle.com/blastchar/telco-customer-churn

I also got:

lookandsay.py:116: UserWarning: Persisting input arguments took 4.87s to run.

  print(f"{time.time() - t} sec\n"

My example is a SLOW adventofcode solution: https://github.com/HenryFBP/adventofcode/tree/master/2015/10

I am looking for a way to suppress this warning. It seems that in the project I am working on the warning occurs when I run many threads simultaneously and concurrency delays a thread persisting the input arguments. Note that the input argument are relatively small.

Any way how to silent this warning?
