Description

Describe the bug
Following #2547 I tried to run the model gpt-neoxt-chat-base-20b, which is a neox-20B derivative I think and I think it should work.
Inference works if the model is loaded the normal way by HF model.from_pretrained function.

To Reproduce
deepspeed --num_gpus 4 inference-test.py --name togethercomputer/GPT-NeoXT-Chat-Base-20B --batch_size 1 --ds_inference --use_kernel --use_meta_tensor --checkpoint_path '/secondary/thies/gpt-neoxt-chat-base-20b/'

Traceback:

Research direction

Reproduce the command with the gpt-neoxt-chat-base-20b checkpoint, then trace the failure through deepspeed/inference/engine.py, module_inject/load_checkpoint.py, module_inject/replace_module.py, and module_inject/containers/gptneox.py. Compare the checkpoint and target tensor sizes at the reported copy operation; done means checkpoint loading completes and inference runs without the size-mismatch error.
