[BUG] Pythia (GPT-NeoX based) models degrade in generation quality using DeepSpeed Inference

[tokestermw]

Describe the bug Hi, the GPT-NeoX based Pythia model's generation quality is degraded once optimized with DeepSpeed.

Edit (2023/03/07): related to https://github.com/microsoft/DeepSpeed/issues/2777.

To Reproduce

from transformers import pipeline
import deepspeed
import torch

prompt = "As the final model release of GPT-2’s staged release, we’re releasing the largest version (1.5B parameters) of GPT-2 along with code and model weights to facilitate detection of outputs of GPT-2 models. While there have been larger language models released since August, we’ve continued with our original staged release plan in order to provide the community with a test case of a full staged release process. We hope that this test case will be useful to developers of future powerful models, and we’re actively continuing the conversation with the AI community on responsible publication."

gpt2_pipe = pipeline('text-generation', 'gpt2', device=0)
gpt2_pipe(prompt, max_new_tokens=50, return_full_text=False, do_sample=False)

# [{'generated_text': '\n\nWe are also pleased to announce that the GPT-2 model release is now available for download on the GPT-2 website.\n\nThe GPT-2 model release is available for download on the GPT-2 website.'}]

gpt2_pipe.model = deepspeed.init_inference(gpt2_pipe.model, replace_with_kernel_inject =True, replace_method='auto', dtype=torch.half, enable_cuda_graph=False)
gpt2_pipe(prompt, max_new_tokens=50, return_full_text=False, do_sample=False)

# [{'generated_text': '\n\nWe are also pleased to announce that the GPT-2 model release is now available for download on the GPT-2 website.\n\nThe GPT-2 model release is available for download on the GPT-2 website.'}]

pythia_pipe =  pipeline('text-generation', 'EleutherAI/pythia-125m-deduped', device=0)
pythia_pipe(prompt, max_new_tokens=50, return_full_text=False, do_sample=False)

# [{'generated_text': '\n\nWe’re also working on a new model release for GPT-2, which will be released in the next few weeks. We’re working on a new model release for GPT-2, which will be released in the next'}]

pythia_pipe.model = deepspeed.init_inference(pythia_pipe.model, replace_with_kernel_inject =True, replace_method='auto', dtype=torch.half, enable_cuda_graph=False)
pythia_pipe(prompt, max_new_tokens=50, return_full_text=False, do_sample=False)

# [{'generated_text': '\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nof the GTS of the G. The GTS of the G. The G. The G. The G. The G. The G. The G. The'}]

Expected behavior Get the same generation results w/ and w/o DeepSpeed for Pythia models.

Hi @satpalsr , I've updated to DeepSpeed 0.8.2, but I'm getting the same results:

Looks like version 0.9.4 works :) Closing.

Guessing llama support fixed the gpt-neox type models: https://github.com/microsoft/DeepSpeed/pull/3425
