cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseCheckpointConverter#

class cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseCheckpointConverter[source]#

Bases: cerebras.modelzoo.tools.checkpoint_converters.base_converter.BaseDictionaryConverter, abc.ABC

Converts between checkpoint state_dict formats.

Methods

`convert`
`convert_all_keys`
`convert_helper`	Converts all keys in a checkpoint from converter_indices.direction format to the other format.
`convert_key`	Attempts to convert the old key by matching against the list of conversion rules.
`extract_model_dict`	Hook to extract model state dicts out of the input/output checkpoint.
`file_formats`
`formats`
`get_config_converter_class`
`get_converter_indices`
`init_output_checkpoint`	(Pre)Initializes the output checkpoint at a supplied path.
`load`
`post_checkpoint_convert`	Hook executes after checkpoint conversion.
`post_model_convert`	Hook executes right after model conversion.
`pre_checkpoint_convert`	Hook executes before checkpoint conversion.
`pre_model_convert`	Hook executes right before model conversion.
`replaceKey`	Copies value that exists at old_state_dict's old_key to new_state_dict's new_key.
`save`
`supports_conversion`

abstract classmethod init_output_checkpoint(file_without_ext, converter_indices, **kwargs)[source]#

(Pre)Initializes the output checkpoint at a supplied path. This is used in streaming conversion when the checkpoint is written to file as conversion is performed rather than accumulating the full checkpoint in memory and saving to file at the very end.

convert_helper(input_checkpoint, configs, converter_indices, output_checkpoint={}, drop_unmatched_keys=False, no_progress_bar=True, debug=False)[source]#

Converts all keys in a checkpoint from converter_indices.direction format to the other format. Conversion will fail if at least one of the keys did not match on any conversion rules and drop_unmatched_keys is not enabled. Returns the newly converted checkpoint.

pre_model_convert(old_state_dict, new_state_dict, configs, converter_indices, drop_unmatched_keys)[source]#

Hook executes right before model conversion.

post_model_convert(old_state_dict, new_state_dict, configs, converter_indices, drop_unmatched_keys, key_prefix='')[source]#

Hook executes right after model conversion.

pre_checkpoint_convert(input_checkpoint, output_checkpoint, configs, converter_indices)[source]#

Hook executes before checkpoint conversion.

extract_model_dict(input_checkpoint, output_checkpoint, configs, converter_indices)[source]#

Hook to extract model state dicts out of the input/output checkpoint.

post_checkpoint_convert(input_checkpoint, output_checkpoint, configs, converter_indices)[source]#

Hook executes after checkpoint conversion.

convert_key(old_key, old_state_dict, new_state_dict, from_index, match_start=0, prefix='', action_fn_args=None, debug=False)#

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.

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.
