🚀安装使用

安装 PaddlePaddle

请在 PaddlePaddle 官网按照您的运行环境,安装 develop 版的 PaddlePaddle。

安装完毕之后,运行以下命令,验证 Paddle 是否安装成功。

python -c "import paddle; paddle.utils.run_check()"

如果出现 PaddlePaddle is installed successfully! Let's start deep learning with PaddlePaddle now. 信息,说明您已成功安装,可以继续安装 PaddleScience。

安装 PaddleScience

  1. 基础功能安装

    从以下三种安装方式中,任选一种均可安装。

    • git 源码安装[推荐]

      执行以下命令,从 github 上 clone PaddleScience 源代码,并以 editable 的方式安装 PaddleScience。

      git clone -b develop https://github.com/PaddlePaddle/PaddleScience.git
      # 若 github clone 速度比较慢,可以使用 gitee clone
      # git clone -b develop https://gitee.com/paddlepaddle/PaddleScience.git
      
      cd PaddleScience
      
      # install paddlesci with editable mode
      pip install -e . -i https://pypi.tuna.tsinghua.edu.cn/simple
    • pip 安装

      执行以下命令以 pip 的方式安装最新版本的 PaddleScience。

      pip install -U paddlesci
    • 设置 PYTHONPATH

      如果在您的环境中,上述两种方式都无法正常安装,则可以选择本方式,在终端内将环境变量 PYTHONPATH 临时设置为 PaddleScience绝对路径,如下所示。

      cd PaddleScience
      export PYTHONPATH=$PYTHONPATH:$PWD # for linux
      set PYTHONPATH=%cd% # for windows
      pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple # manually install requirements

      注:上述方式的优点是步骤简单无需安装,缺点是当环境变量生效的终端被关闭后,需要重新执行上述命令设置 PYTHONPATH 才能再次使用 PaddleScience,较为繁琐。

  2. 验证安装

    python -c "import ppsci; ppsci.utils.run_check()"
  3. 开始使用

    import ppsci
    
    # write your code here...

如需基于复杂几何文件(*.stl, *.mesh, *.obj)文件进行训练、测试等流程,请参考完整安装流程:安装与使用
