mlflow-export-import - Open Source Tests

Overview

Open source MLflow Export Import tests use two MLflow tracking servers:

  • Source tracking for exporting MLflow objects.
  • Destination tracking server for importing the exported MLflow objects.

Setup

See the Setup section.

Test Configuration

Test environment variables.

Name Required Description
MLFLOW_TRACKING_URI_SRC yes URI of source tracking server
MLFLOW_TRACKING_URI_DST yes URI of destination tracking server
MLFLOW_EXPORT_IMPORT_OUTPUT_DIR no If set, will use this as the export output directory instead of tempfile.TemporaryDirectory()

Run tests

Use the run_tests.sh script to run the tests and and specify the source and destination tracking server port number. Output will be in the run_tests.log file.

The script does the following:

  • Launches a source MLflow tracking server and destination MLflow tracking server in the background.
  • Runs tests against these servers with pytest.
  • Tears down the two MLflow tracking servers.

Example
