Submission error: " [bt] (6) /usr"

Insurance pricing game
18

Ok, so I did more experimenting. It looks like I was able to successfully send my submission by doing 3 things:

  1. Completely reset the colab notebook using restart runtime under the runtime menu.
  2. Using the trick above to install version 1.2.0.1 of XGBoost
  3. Use save() and load() instead of xgb.save() and xgb.load()

Hope it can help
