# LLaMA-MoE-v1-3.5B (2/8) |
|
|
|
[[💻 Code]](https://github.com/pjlab-sys4nlp/llama-moe) | [[📜 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](https://huggingface.co./meta-llama/Llama-2-7b-hf). |
|
You can find the code for training this model at [this repo](https://github.com/pjlab-sys4nlp/llama-moe). |
|
|
|
💎 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](https://arxiv.org/). |
|
|
|
## 🚀 QuickStart |
|
|
|
```python |
|
# 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 |
