The total_amount column has nulls so the dataset is bullshit and not useful for this lab

I think there was some issue with the data in bq - taxi one. many values were null which required to adjust the first query

The model creation return the following error: "Failed to calculate mean since the entries in corresponding column 'total_amount' are all NULLs." You need to exclude 'total_amount' from input training data instead of excluding 'tip_amount'.
