LLaMA-MoE-v1-3.5B (2/8)
[💻 Code] | [📜 Technical Report]
👋 Very nice to meet you here~
❤️ This repo contains the model LLaMA-MoE-v1-3.5B (2/8), which activates 2 out of 8 experts (3.5B parameters).
This model is NOT fine-tuned by instruction pairs, so it may not be good enough to act like a chatbot.
📢 LLaMA-MoE is a series of Mixture-of-Expert (MoE) models based on LLaMA-2. You can find the code for training this model at this repo.
💎 This series of models are obtained by partitioning original LLaMA FFNs into experts and further continual pre-training. The total model size is only 6.7B parameters, which is very convenient for deployment and research usage. More details could be found at our technical report.
🚀 QuickStart
# python>=3.10
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_dir = "llama-moe/LLaMA-MoE-v1-3_5B-2_8"
tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_dir, torch_dtype=torch.bfloat16, trust_remote_code=True)
model.eval()
model.to("cuda:0")
input_text = "Suzhou is famous of"
inputs = tokenizer(input_text, return_tensors="pt")
inputs = inputs.to("cuda:0")
pred = model.generate(**inputs, max_length=50, temperature=0.0)
print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))
# Suzhou is famous of its beautiful gardens. The most famous one is the Humble Administrator's Garden. It is a classical Chinese garden with a history of more than 600 years. The garden is divided into three
