## ๐ก Model description
|
| 15 |
-
This repo contains a large language model (OceanGPT) for ocean science tasks trained with [KnowLM](https://github.com/zjunlp/KnowLM).
|
| 16 |
-
It should be noted that the OceanGPT is constantly being updated, so the current model is not the final version.
|
| 17 |
-
|
| 18 |
-
OceanGPT-7B-v0.2 is based on Qwen2-7B and trained on a bilingual dataset in Chinese and English.
|
| 19 |
-
## ๐ Intended uses
|
| 20 |
-
You can download the model to generate responses or contact the [email](bizhen_zju@zju.edu.cn) for the online test demo.
|
| 21 |
-
|
| 22 |
-
## ๐ ๏ธ How to use OceanGPT
|
| 23 |
-
We wil provide several examples soon and you can modify the input according to your needs.
|
| 24 |
-
|
| 25 |
-
```python
|
| 26 |
-
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 27 |
-
import torch
|
| 28 |
-
device = "cuda" # the device to load the model onto
|
| 29 |
-
|
| 30 |
-
model = AutoModelForCausalLM.from_pretrained(
|
| 31 |
-
"zjunlp/OceanGPT-7B-v0.2",
|
| 32 |
-
torch_dtype=torch.bfloat16,
|
| 33 |
-
device_map="auto"
|
| 34 |
-
)
|
| 35 |
-
tokenizer = AutoTokenizer.from_pretrained("zjunlp/OceanGPT-7B-v0.2")
|
| 36 |
-
|
| 37 |
-
prompt = "Which is the largest ocean in the world?"
|
| 38 |
-
messages = [
|
| 39 |
-
{"role": "system", "content": "You are a helpful assistant."},
|
| 40 |
-
{"role": "user", "content": prompt}
|
| 41 |
-
]
|
| 42 |
-
text = tokenizer.apply_chat_template(
|
| 43 |
-
messages,
|
| 44 |
-
tokenize=False,
|
| 45 |
-
add_generation_prompt=True
|
| 46 |
-
)
|
| 47 |
-
model_inputs = tokenizer([text], return_tensors="pt").to(device)
|
| 48 |
-
|
| 49 |
-
generated_ids = model.generate(
|
| 50 |
-
model_inputs.input_ids,
|
| 51 |
-
max_new_tokens=512
|
| 52 |
-
)
|
| 53 |
-
generated_ids = [
|
| 54 |
-
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
|
| 55 |
-
]
|
| 56 |
-
|
| 57 |
-
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
|
| 58 |
-
```

## ๐ ๏ธ How to evaluate your model in OceanBench
|
| 61 |
-
|
| 62 |
-
We wil provide several examples soon and you can modify the input according to your needs.
|
| 63 |
-
|
| 64 |
-
*Note: We are conducting the final checks on OceanBench and will be uploading it to Hugging Face soon.
|
| 65 |
-
|
| 66 |
-
```python
|
| 67 |
-
>>> from datasets import load_dataset
|
| 68 |
-
|
| 69 |
-
>>> dataset = load_dataset("zjunlp/OceanBench")
|
| 70 |
-
```
