Python Client for MLflow

Python client for MLflow REST API.

Features:

• Minimal dependencies
• Unlike MLflow Tracking client all REST API methods and params are exposed to user.
• MLflow URL is passed via constructor argument instead of env variable, so multiple client instances could be created in the same Python interpreter.
• Basic and Bearer auth are supported (via constructor args too).
• All class fields are validated with pydantic.
• All methods and classes are documented.

Limitations:

• There is no integration with ML frameworks and libraries. You should use official MLflow client instead.
• There is no integration with S3 or other artifact storage type. You should access it directly with boto3 or other client.
• Supported MLflow versions: from 1.17.0 to 1.23.0. It is possible to use client with older MLflow versions (e.g. 1.10.0), but this is not guaranteed.
• Only Python 3.7+ is supported. Python 3.6 and lower already reached end of life.
