+# Ascend NPU 加速
+
+## 简介
+
+本文档介绍如何在 Ascend NPU 上使用 MinerU。本文档内容已在`华为Atlas 800T A2`服务器上测试通过。
+```
+CPU：鲲鹏 920 aarch64 2.6GHz
+NPU：Ascend 910B 64GB
+OS：openEuler 22.03 (LTS-SP3)
+```
+由于适配 Ascend NPU 的环境较为复杂，建议使用 Docker 容器运行 MinerU。
+
+
+## 构建镜像
+请保持网络状况良好，并执行以下代码构建镜像。    
+```bash
+wget https://gitee.com/myhloli/MinerU/raw/master/docker/ascend_npu/Dockerfile -O Dockerfile
+docker build -t mineru_npu:latest .
+```
+如果构建过程中未发生报错则说明镜像构建成功。
+
+
+## 运行容器
+
+```bash
+docker run --rm -it -u root --privileged=true \
+    --ipc=host \
+    --network=host \
+    --device=/dev/davinci0 \
+    --device=/dev/davinci1 \

+## 已知问题
+
+- paddlepaddle使用内嵌onnx模型，仅支持中英文ocr，不支持其他语言
+- layout模型使用layoutlmv3时会发生间歇性崩溃，建议使用默认配置的doclayout_yolo模型
+- 表格解析仅适配了rapid_table模型，其他模型可能会无法使用
