Introduction to a Basic Machine Learning Workflow for Predicting Materials Properties 

Benjamin thanks for the introduction. I think it is the most interesting field in our major.

Hi Benjamin, Thank you so much for the tutorial. This is really helpful. However, I encountered an issue when attempting to implement the code. I received the following error message: TypeError: agg function failed [how->mean, dtype->object] while running this code: mastml_df_clean = mastml_df_filtered.groupby("chemicalFormula Clean", as_index=False).mean() Could you please provide some advice on this matter? Thank you.
