# NPU (华为昇腾)

## 使用方法

首先，请参考 {external+mmcv:doc}`教程 <get_started/build>` 安装带有 NPU 支持的 MMCV。

使用如下命令，可以利用 8 个 NPU 在机器上训练模型（以 ResNet 为例）：

```shell
bash tools/dist_train.sh configs/cspnet/resnet50_8xb32_in1k.py 8 --device npu
```

或者，使用如下命令，在一个 NPU 上训练模型（以 ResNet 为例）：

```shell
python tools/train.py configs/cspnet/resnet50_8xb32_in1k.py --device npu
```
