Please note: The queries yield an error stating that the duration field has NULL values, and had to be adjusted to exclude them

It is not explained in detail, and there are problems in the queries, I had the error "Label column 'duration' has NULL values'" and does not allow to train the model.

Great! But now the duration column in the source table contains NULL and needs to add "WHERE duration IS NOT NULL"

There was an error thrown when calling the SQL query given to train the model (task 2, 3 and 4): Label column 'duration' has NULL values I figured out that it was caused by null values in the duration column. So I added "WHERE duration IS NOT NULL" at the end of each SQL query creating a model, and it worked. This is kind of important since there is no troubleshooting indication for this problem in the instructions, and the checks cannot be validated if I don't train the models.

'where duration is not null' is needed in the creation of the models because: REASONS
