initialize()

classmethod initialize(pipeline_config, model_config=None)

source

Initializes a DeepseekV3_2Config instance from pipeline configuration.

This method creates a config instance with all fields that can be determined from the pipeline configuration, without needing the state_dict. Fields that depend on the state_dict (like norm_dtype, quant_config, etc.) should be set directly after calling this method.

Parameters:

• pipeline_config (PipelineConfig) – The MAX Engine pipeline configuration.
• model_config (MAXModelConfig | None)

Returns:

An initialized DeepseekV3_2Config instance.

Return type:

Self

source

Bases: DeepseekV3Model
