AssertionError: Fail to convert pytorch model

[anthony-intel]

this is using the example code only

from transformers import AutoTokenizer, TextStreamer
from intel_extension_for_transformers.transformers import AutoModelForCausalLM
model_name = "Intel/neural-chat-7b-v3-1"     # Hugging Face model_id or local model
prompt = "Once upon a time, there existed a little girl,"

tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
inputs = tokenizer(prompt, return_tensors="pt").input_ids
streamer = TextStreamer(tokenizer)

model = AutoModelForCausalLM.from_pretrained(model_name, load_in_4bit=True)
outputs = model.generate(inputs, streamer=streamer, max_new_tokens=300)
print(outputs)

yields

Hi, this issue seems to have the same reason as #193. pip install neural_speed won't install all packages from requirements.txt and we are trying to fix it now. You can use pip install -r requirements.txt for a quick fix. Thanks.

@zhentaoyu thanks - looking forward to the fix
