hello everyone.
Is building Pytorch on windows using visual studio 2019 supported?
OK, This is what I have done to build pytorch on windows. Using Visual Studio 2019 enterprise (16.7.2) :
git clone --branch v1.6.0 https://github.com/pytorch/pytorch.git pytorch-1.6.0
cd pytorch-1.6.0
git submodule update --init --recursive
set CUDAHOSTCXX=
set DISTUTILS_USE_SDK=1
for /f "usebackq tokens=*" %i in (`"%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" -version [15^,16^) -products * -latest -property installationPath`) do call "%i\VC\Auxiliary\Build\vcvarsall.bat" x64 -vcvars_ver=14.27
python setup.py build --cmake-only
cmake-gui
and this is what I did afterward:
I managed to open the visual studio and nearly build everything. but out of 46 targets, 11 failed with these errors.
I dont have any cuda installed and I’m using the cpu version.
Here are the errros I get:

What am I missing here?
please note that this is the default, and I have not yet changed to MT yet. its all MD by default.
any help is greatly apprecaited.
@peterjc123
This is related to this : https://github.com/oneapi-src/oneDNN/issues/812
Also it seems the change is a one liner .i.e just change auto zero_val = (data_t)0; to const data_t zero_val = 0; in src/cpu/gemm_convolution_utils.cpp and thats all.

Hi,
We updated our version of oneDNN recently and this fix should have been pulled in. Do you still see this problem with the current master branch?
Hi,
Yes I have seen the workaround and it indeed fixes the issue. I have only used this with 1.6.0 not sure if there is any issues with the master branch though I believe the master should be fine too if the fix is already merged.
@albanD I built the latest master and all is fine as far as the building process goes. just wanted to update you on this once again

BTW, we usually use python tools\build_libtorch.py when building LibTorch. If you need /MT, please set BUILD_SHARED_LIBS to OFF and then start the build.

Thanks a lot really appreciate it. I surely will give that a try and if something turns up I’ll report back.
I could build the libs both MT and MD using the normal cmake way(setup.py build --cmake-only). but
I’m getting lots of linker errors when I run that script like this :
cd tools
set BUILD_SHARED_LIBS=OFF

could you kindly point that out?
How did you build for /MT?
How you activated the VC shell more than once?

Thanks a lot really appreciate your time and kind help.
How did you build for
/MT?
Concerning how I built the \MT . Since I could successfully create a cmake project and then a visual studio project using what I mentioned in post #2 , I went on to each single project, right clicked on each of them, went to properties, C/C++ -> Code Generation -> Runtime Library and flipped the option from MD to MT! and it successfully built the libs. although the Python_sth failed, but the main libs that I were after were successfully built.
The weird thing though was that, there were no .dlls despite the fact that I only changed the library runtime option and everything else was intact. I only got .lib files plus .exp files. I used them to successfully link my application , however for execution it needed the dll part (c10.dll for example) which shamelessly I used the prebuilt ones from Pytorch which I believe are built as MD!
I didn’t face any issues though, the app seemed to be running just fine. the lib version (static build) was fine though.
So I wanted to know is this normal or did I just messed something up ? (I have a gut feeling I did!)
How you activated the VC shell more than once?
I’m not sure, I didn’t do anything special, maybe my repeated tries resulted in that?
Anyway, your proposed change seems to be working and its being compiled now. I’ll report back how it goes.
Update:
Its finished successfully and created 247 targets!
Something to note though why is torch_cpu.lib 2.05 GB!? this is huge! :
wouldn’t this be an issue? specially in ram consumption? This is not related to libtorch anymore, but I’d really appreciate an explanation on this if possible. I know statically linking allows for only the needed parts to be loaded into ram, but this huge amount kind of scares me that lots of stuff is going to end up there (possibly as duplicates?) when I built using my first attempt, my torch_cpu.lib was around 10/20 MBs if I’m not mistaken. how come this is 2GB! is it because this is built statically and I built it dynamically? (in that case, why did I not have any .dll files accompaning the lib files like usual?)
I guess the way you try to build for /MT only enables some of the part into /MT. Because some of the flags relies on BUILD_SHARED_LIBS.
Yes, in my memory it is just that big. That’s definitely an issue. But we don’t have time to optimize it. Generally speaking, static libs will be larger than the dynamic libs because all dependencies will be added to the static lib when linking (since /WHOLEARCHIVE is used).

Thanks a lot really apprecaite your kind help on this. I’m really grateful.
Excuse me, but I noticed lots of
info C5002: Omp simd loop not vectorized due to reason ‘1200’
during compilation process. is this normal? or is it another bug from visual studio 2019? Do you see this in your builds as well?
I also noticed after statically linking with the newly built libs, upon exeuting the executable, it requires c10.dll and torch_cpu.dll :
what am I missing here? it shouldnt be needing the dlls !
Nope, it is not a bug. It is just VS adds support for the #pragma omp simd clauses in 2019. But they have strict requirements so they cannot be automatically vectorized. In VS2017, they are not even recognized.
It shouldn’t be. Could you please show me how you linked against those libs?
Thanks a lot. do you need to see how my test application is linked to these libs? i.e. how the VS project properties is configured?
Yes, please. [20 characters]

Note:
Just to clear any possible confusion here, I first showed the lib directory I built statically (using the approach mentioned above) and then copied it to the libtorch-release-latest folder which I have in my dependency folder and is showing in the Linker’s Additional Library Directories options. so I’m using the libs that I built earlier not something else.
Previously that it built fine but needed the dll at runtime, I was using the libs I made earlier from the cmake project (explained here) now that I used the new static libs, I’m getting these linker errors!.
Maybe you’ll need some additional macros. __declspec(dllimport) shouldn’t be appearing in the log since you are using static build.
BTW, did you recreate the project after the build? Some flags have changed when you switch from dynamic build to static build. (e.g. C10_BUILD_SHARED_LIBS)
Do you mean the libtorch build directory? or are you referring to my own project that uses libtorch? if its the first one, no I dont think so. I just ran the commands. but if you refer to the latter, I rebuilt everything every time so all modules (libs, etc) get built again and I dont use any prebuilt/possibly with wrong config libs.
