## 环境准备
- [PaddlePaddle安装](https://www.paddlepaddle.org.cn/install/quick)
* 版本要求:PaddlePaddle>=2.1.0
- PaddleRS安装
PaddleRS代码会跟随开发进度不断更新,可以安装develop分支的代码使用最新的功能,安装方式如下:
```
git clone https://github.com/PaddleCV-SIG/PaddleRS
cd PaddleRS
git checkout develop
pip install -r requirements.txt
python setup.py install
```
## 开始训练
* 在安装PaddleRS后,使用如下命令开始训练,代码会自动下载训练数据, 并均使用单张GPU卡进行训练。
```commandline
export CUDA_VISIBLE_DEVICES=0
python tutorials/train/semantic_segmentation/deeplabv3p_resnet50_multi_channel.py
```
* 若需使用多张GPU卡进行训练,例如使用2张卡时执行:
```commandline
python -m paddle.distributed.launch --gpus 0,1 tutorials/train/semantic_segmentation/deeplabv3p_resnet50_multi_channel.py
```
使用多卡时,参考[训练参数调整](../../docs/parameters.md)调整学习率和批量大小。
## VisualDL可视化训练指标
在模型训练过程,在`train`函数中,将`use_vdl`设为True,则训练过程会自动将训练日志以VisualDL的格式打点在`save_dir`(用户自己指定的路径)下的`vdl_log`目录,用户可以使用如下命令启动VisualDL服务,查看可视化指标
```commandline
visualdl --logdir output/deeplabv3p_resnet50_multi_channel/vdl_log --port 8001
```
