The OPT model has inconsistent checkpoint layer names:
125m, 1.3b, 2.7b, 66b:
model.decoder.*
andlm_head.weights
6.7b, 13b, 30b:
decoder.*
and nolm_head.weights
350m:
decoder.*
andproject_*
This PR extends support to all OPT models except 350m. We will have a future PR to handle the unique features of this model.
As part of this PR, wildcards can now be used in the model container
PARAM_MAPPINGS
, such as*decoder.embed_tokens.weights
