Download Model
The base-model microsoft/Phi-3-mini-4k-instruct currently relies on
the latest dev-version transformers and torch.
Also, it needs trust_remote_code=True as an argument of the from_pretrained function.
pip install git+https://github.com/huggingface/transformers accelerate
pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu
Additionally, LoRA adapter requires the peft package.
pip install peft
Now, let's start to download the adapter.
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "Mike0307/Phi-3-mini-4k-instruct-chinese-lora"
model = AutoModelForCausalLM.from_pretrained(
model_id,
device_map="mps", # mps is for MacOS users
torch_dtype=torch.float32, # try float16 if needed
trust_remote_code=True,
attn_implementation="eager", # without flash_attn
)
tokenizer = AutoTokenizer.from_pretrained(model_id)
Inference Example
# M2 pro takes about 3 seconds in this example.
input_text = "<|user|>將這五種動物分成兩組。\n老虎、鯊魚、大象、鯨魚、袋鼠 <|end|>\n<|assistant|>"
inputs = tokenizer(
input_text,
return_tensors="pt"
).to(torch.device("mps")) # mps is for MacOS users
outputs = model.generate(
**inputs,
temperature = 0.0,
max_length = 500,
do_sample = False
)
generated_text = tokenizer.decode(
outputs[0],
skip_special_tokens=True
)
print(generated_text)
Streaming Example
from transformers import TextStreamer
streamer = TextStreamer(tokenizer)
input_text = "<|user|>將這五種動物分成兩組。\n老虎、鯊魚、大象、鯨魚、袋鼠 <|end|>\n<|assistant|>"
inputs = tokenizer(
input_text,
return_tensors="pt"
).to(torch.device("mps")) # Change mps if not MacOS
outputs = model.generate(
**inputs,
temperature = 0.0,
do_sample = False,
streamer=streamer,
max_length=500,
)
generated_text = tokenizer.decode(
outputs[0],
skip_special_tokens=True
)
Example of RAG with Langchain
This reference shows how to customize langchain llm with this phi-3 lora model.
