cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseCheckpointConverter_UnpackedHF_PackedCS#
- class cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseCheckpointConverter_UnpackedHF_PackedCS[source]#
Bases:
cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseCheckpointConverter_HF_CSConverter between a set of unpacked HF checkpoints and a single packed CS checkpoint.
Some CS models consist of separate components which we want to initialize from existing HF checkpoints. For example, initializing the image encoder and text decoder of a multimodal model. This converter class provides an abstraction for using existing HF <-> CS checkpoint converters.
In particular, we specify a list of BaseCheckpointConverter_HF_CS classes through converters() corresponding to each model component. Similarly, we specify another list of directory names through component_names() corresponding to the name of the subdirectory containing the model checkpoint.
During conversion, this converter applies the i-th component converter to the component checkpoint found in the i-th subdirectory name.

Copies value that exists at old_state_dict's old_key to new_state_dict's new_key.

Attempts to convert the old key by matching against the list of conversion rules. The first rule to match is used for conversion (i.e. even if multiple rules would match, the latter ones are never used). Returns True if a conversion occurred.
- get_mup_converter()#
Allows models to override the default muP converters with their own.
- pre_model_convert(old_state_dict, new_state_dict, configs, converter_indices, drop_unmatched_keys)#
Hook executes right before model conversion.
- static replaceKey(old_key, new_key, old_state_dict, new_state_dict, from_index, action_fn_args=None)#
Copies value that exists at old_state_dict’s old_key to new_state_dict’s new_key.
