cooked: <p>The error message “C2059: syntax error: ‘bad suffix on number’” usually occurs when there is a problem with the syntax of a number or a literal in your code.</p>
<p>In the context of building PyTorch from source, this error is most likely caused by an incorrect version of the Visual Studio compiler. PyTorch requires the use of the Visual Studio 2019 compiler, and if you are using an older version, you may encounter this error.</p>
<p>To fix this error, you can try the following steps:</p>
<p>Check that you have the correct version of the Visual Studio compiler installed. You can download and install Visual Studio 2019 Community edition from the official Microsoft website.</p>
<p>Make sure that the correct version of the compiler is being used in the build process. You can set the compiler version by running the following command in the command prompt before building PyTorch:</p>
<p>arduino<br>
Copy code<br>
set “CMAKE_CXX_COMPILER=C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64\cl.exe”<br>
Note that the exact path to the compiler may vary depending on your installation.</p>
<p>If you are using a different build system, such as CMake, make sure that it is configured to use the correct version of the Visual Studio compiler.<br>
If these steps do not resolve the issue, you may need to provide more details about the specific error message and your build environment to diagnose the problem further.</p>
<p>Regards,<br>
Rachel Gomez</p>
