Libraries

How to use microsoft/Phi-3-mini-4k-instruct with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="microsoft/Phi-3-mini-4k-instruct", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("microsoft/Phi-3-mini-4k-instruct", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("microsoft/Phi-3-mini-4k-instruct", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Phi-3 is not generating from input embeddings [BUG]RuntimeError: shape '[-1, 0]' is invalid for input of size 5

When I am trying to generate using embeddings the prepare_inputs_for_generation function requires the past_key_values to be None but it is an empty tensor (at line 1326)
code:

layer = model.get_input_embeddings()
input_ids = tokenizer(prompt, return_tensors='pt').to('cuda')
inp_embeds = layer(input_ids.input_ids)
outputs = model.generate(
                inputs_embeds=inp_embeds,
                max_new_tokens=20,
                use_cache = True,
                # do_sample=True,
            )

RuntimeError: shape '[-1, 0]' is invalid for input of size 5
In modeling_phi3.py line 1326:
given: if inputs_embeds is not None and past_key_values is None:
fix: if (inputs_embeds is not None and past_key_values is None) or (inputs_embeds is not None and len(past_key_values) == 0):

hey @Ryz3n758 you might find Impulse AI (https://www.impulselabs.ai/) useful. we make it super easy to fine-tune and deploy open source models. i know not relevant to your problem above but might be easier to use us to fine tune and deploy
