关于算法:FATE联邦学习debug-No-module-named-‘federatedml‘

间接 pip install federatedml 是无奈找失去这个库的。
这个的起因是环境变量的事件，因为在部署文档中，自身提醒咱们要更新一些环境变量，如果不 export 那些变量，上面的 fate_test 其实也是无奈测试胜利的。

关上bin/init_env.sh，其内容如下

export PATH=$PATH:$JAVA_HOME/bin

能够看到这个库自身在下载的 FATE 包里

那接下来其实能够给 conda 的 python 解释器增加环境变量，如何做？
先查看下以后的 python 解释器的门路echo $PATH，echo $PYTHONPATH$，因为我应用的是 conda 虚拟环境，我就应用 conda 自带的虚拟环境的环境变量工具增加上 init_env 那两个门路就行了

init_env 文件想 export PYTHONPATH

export PYTHONPATH=/root/Downloads/standalone_fate_install_1.10.0_release/fate/python:/root/Downloads/standalone_fate_install_1.10.0_release/fateflow/python

那用 conda 的话就间接

conda-env config  vars set PYTHONPATH=/root/Downloads/standalone_fate_install_1.10.0_release/fate/python:/root/Downloads/standalone_fate_install_1.10.0_release/fateflow/python

输出后，提醒 To make your changes take effect please reactivate your environment
这样就能够了。

如果你不必 conda，你也能够间接跟文件里的那样间接输出 “
export PYTHONPATH=/root/Downloads/standalone_fate_install_1.10.0_release/fate/python:/root/Downloads/standalone_fate_install_1.10.0_release/fateflow/python“，应该也行，然而你的代码编辑器大概率还会报错，然而运行是能够运行的。

如果还想代码编辑器不报错，能够 在 vscode 的 python 插件里的 extra path setting 里退出 federatedml 的目录。能够参考自己的答复：https://segmentfault.com/q/1010000043514241/a-1020000043868000
