从C＃代码激活conda环境（或手动打开cmd与从c＃打开cmd有什么区别？） [英] Activating conda environment from c# code (or what is the differences between manually opening cmd and opening it from c#?)

问题描述

我想使用conda环境（dlwin36）在Windows上运行gpu加速的python脚本。

I want to run a gpu accelerated python script on windows using conda environment (dlwin36).

我正在尝试激活dlwin36并执行脚本：

I’m trying to activate dlwin36 and execute a script:

1）激活dlwin36

1) activate dlwin36

2）设置KERAS_BACKEND = tensorflow

2) set KERAS_BACKEND=tensorflow

3）python myscript.py

3) python myscript.py

如果我在计算机上手动打开cmd并输入： activate dlwin36
，则可以正常工作。

If I manually open cmd on my machine and write:"activate dlwin36" it works.

但是当我尝试从c＃打开cmd时，我得到：

But when I try opening a cmd from c# I get:

激活未被识别为内部或外部命令，

"activate is not recognized as an internal or external command, operable program or batch file."

命令链接：

var start = new ProcessStartInfo();
start.FileName = "cmd.exe";
start.Arguments = "/c activate dlwin36&&set KERAS_BACKEND=tensorflow&&python myscript.py";
Process.Start(start).WaitForExit();

（我已经测试了UseShellExecute，LoadUserProfile和WorkingDirectory的几种变体）

(I’ve tested several variations of UseShellExecute, LoadUserProfile and WorkingDirectory)

重定向标准输入：

var commandsList = new List<string>();
commandsList.Add("activate dlwin36");
commandsList.Add("set KERAS_BACKEND=tensorflow");
commandsList.Add("python myscript.py");

var start = new ProcessStartInfo();
start.FileName = "cmd.exe";
start.UseShellExecute = false;
start.RedirectStandardInput = true;
var proc = Process.Start(start);
commandsList.ForEach(command => proc.StandardInput.WriteLine(command));

（我已经测试了LoadUserProfile和WorkingDirectory的几种变体）

(I’ve tested several variations of LoadUserProfile and WorkingDirectory)

在两种情况下，我都遇到相同的错误。

In both cases, I got the same error.

似乎手动打开cmd与从c＃打开cmd之间存在差异。 p>

It seems that there is a difference between manually opening cmd and opening it from c#.

推荐答案

如果将来可以帮助任何人。我发现您必须从C：\驱动器运行激活。

If this is gonna help anyone in the future. I found that you must run the activation from C:\ drive.
