+## Code implementation of Qwen2 based embeddings
+
+This model code is for Qwen2 based embedding models.
+
+We enable the bidirectional attention by default.
+
+### Usage
+
+1. Download the `configuration.py` and `modeling.py` to your saved `gte-Qwen2` model directory.
+2. Replace the `modeling_qwen.` with `modeling.` in `auto_map` field of `config.json`.
+
+
+### Recommendation: Enable Unpadding and Acceleration with `xformers`
+
+This code supports the acceleration of attention computations using `xformers`,
+which can automatically choose the optimal implementation based on the type of device, such as `flash_attn`.
+Therefore, we can also achieve significant acceleration on old devices like the V100.
+
+
+Firstly, install `xformers` (with `pytorch` pre-installed):
+```
+if pytorch is installed using conda:
+    conda install xformers -c xformers
+elif pytorch is installed using pip:
+    # cuda 11.8 version
+    pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu118
+    # cuda 12.1 version
+    pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu121
+```
+For more information, refer to [Installing xformers](https://github.com/facebookresearch/xformers?tab=readme-ov-file#installing-xformers).
+
+Then, when loading the model, set `unpad_inputs` and `use_memory_efficient_attention` to `true`,
+and set `torch_dtype` to `torch.float16` (or `torch.bfloat16`) to achieve the acceleration.
+
+```python
+import torch
+from transformers import AutoModel, AutoTokenizer
+
+path = 'Alibaba-NLP/gte-Qwen2-1.5B-instruct'
+device = torch.device('cuda')
+tokenzier = AutoTokenizer.from_pretrained(path, trust_remote_code=True)
+model = AutoModel.from_pretrained(
+    path,
+    trust_remote_code=True,
+    unpad_inputs=True,
+    use_memory_efficient_attention=True,
+    torch_dtype=torch.float16
+).to(device)
+
+inputs = tokenzier(['test input'], truncation=True, max_length=8192, padding=True, return_tensors='pt')
+
+with torch.inference_mode():
+    outputs = model(**inputs.to(device))
+
+```
+
+Alternatively, you can directly modify the `unpad_inputs` and `use_memory_efficient_attention` settings to `true` in the model's `config.json`,
+eliminating the need to set them in the code.

+## Qwen2 模型代码实现
+
+此模型代码适用于基于`Qwen2` 的文本表示模型。
+
+默认启用双向注意力机制。
+
+
+### 使用方法
+
+1. 下载此仓库中的 `configuration.py` 和 `modeling.py` 到你本地保存的 `gte-Qwen2` 模型目录
+2. 将 `config.json` 的 `auto_map` 下所有的 `modeling_qwen.` 替换为 `modeling.`
+
+### 推荐：启用 Unpadding 和 xformers 加速
+
+此代码支持使用 `xformers` 加速 attention 计算，可以根据设备类型自动选择优化实现，比如 `flash_attn`。
+通过 `xformers`，在不能支持 `flash_attn` 的旧设备比如`V100`上也可以获得极大的加速。
+
+首先，安装 `xformers`（需要预先安装`pytorch`）：
+```
+if pytorch 使用 conda 安装 :
+    conda install xformers -c xformers
+
+elif pytorch 使用 pip 安装 :
+    # cuda 11.8 version
+    pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu118
+    # cuda 12.1 version
+    pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu121
+```
+更多信息可参考 [installing-xformers](https://github.com/facebookresearch/xformers?tab=readme-ov-file#installing-xformers)。
+
+然后，加载模型时设置 `unpad_inputs` 和 `use_memory_efficient_attention` 为 `true`，并设置 `torch_dtype` 为 `torch.float16` (or `torch.bfloat16`)，即可获得加速。
+
+```python
+import torch
+from transformers import AutoModel, AutoTokenizer
+
+path = 'Alibaba-NLP/gte-Qwen2-1.5B-instruct'
+device = torch.device('cuda')
+tokenzier = AutoTokenizer.from_pretrained(path)
+model = AutoModel.from_pretrained(
+    path,
+    trust_remote_code=True,
+    unpad_inputs=True,
+    use_memory_efficient_attention=True,
+    torch_dtype=torch.float16
+).to(device)
+
+inputs = tokenzier(['test input'], truncation=True, max_length=8192, padding=True, return_tensors='pt')
+
+with torch.inference_mode():
+    outputs = model(**inputs.to(device))
+
+```
+也可以直接修改模型的 `config.json` 中 `unpad_inputs` 和 `use_memory_efficient_attention` 为 `true`，省去代码中的设置。
