thank your for your article! Indeed I have exactly the problem your are describing.
I have already tested PySpark, which I have described it in this article: https://towardsdatascience.com/how-to-speed-up-your-python-code-through-pyspark-e3296e39da6
But now, I'd like to try CatBoost. Do you know any available resource about it, such a ready notebook or tutorial?
Thank you again for your article,
