FAQ

How does Driverless AI detect the ID column?

The ID column logic is that the column is named ‘id’, ‘Id’, ‘ID’ or ‘iD’ exactly. (It does not check the number of unique values.) For now, if you want to ensure that your ID column is downloaded with the predictions, then you would want to name it one of those names.

How can you download the predictions onto the machine where Driverless AI is running?

When you select “Score on Another Dataset” the predictions will be automatically downloaded to the machine where Driverless AI is running. It will be saved in the following locations:

  • Training Data Predictions: tmp/experiment_name/train_preds.csv
  • Testing Data Predictions: tmp/experiment_name/test_preds.csv
  • New Data Predictions: tmp/experiment_name/automatically_generated_name. Note that the automatically generated name will match the name of the file downloaded to your local computer.

If I drop several columns from Train data set, will Driveless AI understand that it needs to drop the same columns from Test data set?

If you drop columns from the dataset, Driverless AI will do the same on the test dataset.

How can I change my username and password?

The username and password is tied to the experiments you have created. For example, if I log in with the username/password: megan/megan and start an experiment, then I would need to log back in with the same username and password to see those experiments. The username and password, however, does not limit your access to Driverless AI. If you want to use a new user name and password, you can log in again with a new username and password, but keep in mind that you won’t see your old experiments.

How can I upgrade to a newer version of Driverless AI?

H2O provides the following set of commands that can you can run on the machine that’s running Driverless AI. Note that these commands only work on Linux environments. These commands are not available for Mac and Windows installations.

h2oai stop     (Stop all instances)
h2oai start    (Start an instance)
h2oai restart  (Restart instance)
h2oai clean    (Removes old containers)
h2oai purge    (Removes old containers and purges tmp and log)
h2oai upgrade  (Upgrades image to Developer latest *unstable*)
h2oai update   (Upgrades image to latest Release)
h2oai ssh      (Attaches to running docker)
h2oai log      (Tails the running server log)
h2oai jupyter  (Fetch the Jupyter URL with token)

To upgrade to the latest version, stop Driverless AI, then run the h2oai update command.
