Azure AutoML maximum columns supported

SoonJoo@Genting 241

Hi,

Is there any documentation on the maximum columns supported by the AML both on the Portal and SDK?

I tried to input a training sets with more than 60k columns and the process failed on the portal but still running on my notebooks.

Wonder is there any limits on the number of columns that we can put it?

Thanks!

@SoonJoo@Genting The limits for a workspace are mentioned in service limits page. But, there is no documented limit on the no. of columns. I think with the portal there could be a limit considering the display or UI support. With the notebook i.e SDK your process might still be running, the only limitation that is documented is the timeout of the experiment with respect to the dataset size with the train AutoMLConfig.

experiment_timeout_hours
Maximum amount of time in hours that all iterations combined can take before the experiment terminates. Can be a decimal value like 0.25 representing 15 minutes. If not specified, the default experiment timeout is 6 days. To specify a timeout less than or equal to 1 hour, make sure your dataset's size is not greater than 10,000,000 (rows times column) or an error results.
