tlc Python Package

The tlc Python package serves as the primary integration point between your machine learning code and the 3LC ecosystem. Integration into an existing codebase is straightforward and can be accomplished by inserting a minimal number of lines into your existing training script.

tlc vs. 3LC

The installable package on PyPi is called 3lc. The installed Python package itself is called tlc due to the limitations of Python package naming conventions. In all other contexts, including the command line interface, 3LC or 3lc is used.

This following sections provide a detailed overview of the package’s capabilities and how to integrate it with your current codebase. See also the Python API documentation for a full breakdown of all the modules, classes and functions in 3LC.
