How can I fix this problem? ( My pytorch version is 1.1.0, cuda is 9.0) Looking forward to your reply.

[zhangyunming]

i have also the problem , how ?

[1023198294]

Same problem, not solved yet

[shuangshuangguo]

I faced the same problem on windows system, and I solved it through setting environment variables.
Please see more details in https://thebadzhang.github.io/Blog/17/04/CL_CL_VS17.html.

Please help us resolve it ASAP

[SUNNYDAY-4176]

Have you solve this problem?

[JotaCe7]

Hi. For this to work you have to make sure that cl command can be called from your prompt. This and this shows solutions for windows 10. But the easiest workaround I found is just add cl.exe dir path to the environmental variables. Default path is "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Tools\MSVC\14.22.27905\bin...". choose the right one accordingly to your architecture.

[mohammadrezanaderi4]

For few of us who cannot read Chinese :

1. Add two paths to the Path item in the environment variable (remember to add a semicolon):
   E:\VS2017\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64;
   E:\VS2017\Common7\IDE
   The first line is the directory of the compiler, choose it according to the computer, but at least HostX86\x86 is available for all platforms, and the 64-bit system is filled in as in the example

2. Create a new LIB variable in the environment variable and add three paths (remember to add a semicolon):
   C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.10.25017\lib\x64;
   C:\Program Files (x86)\Windows Kits\10\Lib\10.0.14393.0\ucrt\x86;
   C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x86;
   The first path is the lib path, if HostX64\x64 is filled in the path variable, then x64 lib is used
   I don’t know if the second path is filled in, but if I fill in the latest version, no problem is found so far.

3. Create a new INCLUDE variable in the environment variable and add two paths (remember to add a semicolon):
   E:\VS2017\VC\Tools\MSVC\14.10.25017\include;
   C:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0\ucrt;
   The second path corresponds to the second path above

4. Click the batch program vcvarall.bat in the path E:\VS2017\VC\Auxiliary\Build. Then open the command line, enter cl, if no error is reported, the configuration is successful...

[bmquynhlinh]

@mohammadrezanaderi4 thank you! problem solved!

[FilipeF12]

@mohammadrezanaderi4 thanks for your solution

but did not fully work for me on windows 10. after I removed the semicolon* and ran the bat as follows:

vcvarsall.bat x86_amd64

then I could run 'cl' in a new command prompt successfully.

*semicolon problem for windows 10 mentioned here:

I have encountered this problem(on Windows) in other python project. In my case, I solved it by

1. change OS like ubuntu. WSL works in my situation.
   or
2. run python code in "x64 Native Tools Command Prompt for VS 2019" which comes from Visual Studio 2019.
   or
3. Add "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx86\x86" into "Path" of your environment variables.
