MKL linking error of the c++ minimal sample

username: Chenoille
cooked: <p>Hello,</p>
<p>I am trying to build the c++ minimal example provided <a href="https://pytorch.org/cppdocs/installing.html" rel="noopener nofollow ugc">here</a> with the MSVC compiler. I can configure it successfully with cmake. But when linking, it states it cannot find the mkl_intel_ilp64.lib. I have the intel oneAPI installed on my machine and I am afraid this causes the error since cmake finds it. What should I do to correct this behaviour?</p>
<p><strong>Error</strong> : LINK : fatal error LNK1104: impossible d’ouvrir le fichier ‘mkl_intel_ilp64.lib’</p>

<li>Latest Libtorch+cpu (1.12.1)</li>

I have the same problem. Did you find a solution to it?<br>
Thanks<br>

cooked: <p>Hello,<br>
The problem was that my cuda compatibility (3.5) was too low for the newest versions of Pytorch. I had to go back to Pytorch 1.6.<br>
If your cuda compatibility is adequate, you can then use <a href="https://github.com/peterjc123/pytorch_dll_load_smoketests" rel="noopener nofollow ugc">this website</a> to check if you have problems with loading dlls on Windows.<br>
I hope it helps.</p>
<p>Have a nice day,<br>
