FAQ and Troubleshooting

Frequently asked questions and answers.

Q: How to debug pipeline execution without actually running it?

A: Using --describe flag for the command line would run the task/pipeline without executing it.

For example:

dbnd run predict_wine_quality --verbose --describe

You can combine it with --verbose to see more logs and --disable-web-tracker to run without reporting to the webserver.

If you submit a task to Kubernetes, add --local-driver to make sure that you run the driver on the local machine and it is shown in the describe output.

Q: How can I debug my task parameters and signature calculation?

A: Using --verbose flag for the command line would print extra information on task parameters.
Use -v -v (verbose=2) to get the full info about the task object to build.

For example:

dbnd run predict_wine_quality --verbose --verbose

You can combine it with --verbose to see more logs and --disable-web-tracker to run without reporting to the webserver.

Q: How can I run my task without sending information to Web UI?

A: You can do that using --disable-web-tracker flag.
