We opensource our **Aquila2** series, now including **Aquila2**, the base language models, namely **Aquila2-7B** and **Aquila2-34B**, as well as **AquilaChat2**, the chat models, namely **AquilaChat2-7B** and **AquilaChat2-34B**, as well as the long-text chat models, namely **AquilaChat2-7B-16k** and **AquilaChat2-34B-16k** |
|
|
|
The additional details of the Aquila model will be presented in the official technical report. Please stay tuned for updates on official channels. |
|
|
|
2023.10.25 🔥 Version 1.2 of Aquila2-34B, AquilaChat2-34B-16K and AquilaChat2-34B models have been updated on ModelHub and Hugging Face. |
|
Among them, the Aquila2-34B model has improved by 6.9% in comprehensive objective evaluation. |
|
The evaluation results of Aquila2-34B v1.2 on MMLU, TruthfulQA, CSL, TNEWS, OCNLI, BUSTM and other exam, understanding and reasoning datasets have respectively increased by 12%, 14%, 11%, 12%, 28%, 18%. |

## Quick Start Aquila2-34B（Chat model） |
|
|
|
### 1. Inference |
|
|
|
```python |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
from transformers import BitsAndBytesConfig |
|
|
|
device = torch.device("cuda") |
|
model_info = "BAAI/Aquila2-34B" |
|
tokenizer = AutoTokenizer.from_pretrained(model_info, trust_remote_code=True) |
|
quantization_config=BitsAndBytesConfig( |
|
load_in_4bit=True, |
|
bnb_4bit_use_double_quant=True, |
|
bnb_4bit_quant_type="nf4", |
|
bnb_4bit_compute_dtype=torch.bfloat16, |
|
) |
|
model = AutoModelForCausalLM.from_pretrained(model_info, trust_remote_code=True, |
|
# quantization_config=quantization_config, # Uncomment this line for 4bit quantization |
|
) |
|
model.eval() |
|
model.to(device) |
|
text = "请给出10个要到北京旅游的理由。" |
|
tokens = tokenizer.encode_plus(text)['input_ids'] |
|
tokens = torch.tensor(tokens)[None,].to(device) |
|
stop_tokens = ["###", "[UNK]", "</s>"] |
|
with torch.no_grad(): |
|
out = model.generate(tokens, do_sample=True, max_length=512, eos_token_id=100007, bad_words_ids=[[tokenizer.encode(token)[0] for token in stop_tokens]])[0] |
|
out = tokenizer.decode(out.cpu().numpy().tolist()) |
|
print(out) |
|
``` |
