Details

The gemma_pytorch architecture is designed as a modular Machine Learning Model Library, primarily focused on efficient inference.

CLI Interface

Provides the command-line entry point for users to interact with the gemma_pytorch library, enabling them to initiate inference, specify model parameters, and manage input/output.

Related Classes/Methods:

• gemma_pytorch.run_inference.main (1:1)
• gemma_pytorch.run_inference.parse_args (1:1)

Model Configuration

Manages and provides all configurable parameters and hyperparameters necessary to define and initialize the Gemma model, such as hidden dimensions, number of layers, and vocabulary size.

Related Classes/Methods:
