+# RankingGPT-qwen-7b
+
+RankingGPT is a text ranker based on large language models with significant in-domain and out-domain effectiveness.
+We provide RankingGPT in different sizes and types, including bloom-560m, bloom-1b1, bloom-3b, bloom-7b, llama2-7b, baichuan2-7b and qwen-7b.
+
+More details please refer to our [paper](https://arxiv.org/abs/2311.16720) and [github](https://github.com/Alibaba-NLP/RankingGPT).
+
+
+## Usage
+
+Code example
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+tokenizer = AutoTokenizer.from_pretrained('zyznull/RankingGPT-qwen-7b',trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained('zyznull/RankingGPT-qwen-7b',trust_remote_code=True).eval()
+
+query='when should a baby walk'
+document='Most babies start to walk around 13 months, but your baby may start walking as early as 9 or 10 months or as late as 15 or 16 months.'
+
+context=f'Document: {document} Query:'
+example=context+query
+
+context_enc = tokenizer.encode(context, add_special_tokens=False)
+continuation_enc = tokenizer.encode(query, add_special_tokens=False)
+model_input = torch.tensor(context_enc+continuation_enc[:-1])
+continuation_len = len(continuation_enc)
+input_len, = model_input.shape
+
+
+with torch.no_grad():
+    logprobs = torch.nn.functional.log_softmax(model(model_input.unsqueeze(dim=0))[0], dim=-1)[0]
+
+logprobs = logprobs[input_len-continuation_len:]
+logprobs = torch.gather(logprobs, 1, torch.tensor(continuation_enc).unsqueeze(-1)).squeeze(-1)
+score = torch.sum(logprobs)/logprobs.shape[0]
+
+print(f"Document: {document[:20] + '...'} Score: {score}")
+```
