Neil, I have not actually tried compiling on Windows.  Good luck!

Hello John

I am not able to build the dependencies viz paths, cwrap and torch7 core package.
But I see MSVC support in CMake. Could you suggest the steps to build torch7 ?

I haven't looked into it myself.  @soumith, who added windows support to cmake?  Was it @andresy?

[Neil]

The License documentation (torch.ch) also claims windows support for core packages.

In the source code I keep finding #ifdef WIN32 all around, but I haven't been able to find updated doc on how to build it for the Windows OS.

Here (http://torch.cogbits.com/doc/install/index.html), under the CMake there are some references to Windows...

[Alfredo Canziani]

Here (https://github.com/torch/torch7-distro/pull/1) there are other information.

@Jonathan, did you manage to compile Torch7 and the nn package for Windows? If yes, could you please post a short tutorial/explanation?

[smth chntla]

Leon Bouttou and his students use Windows. 
The core luajit+rocks, torch7 and nn packages should be compilable via CMake+VisualStudio.

However I HAVE NOT TESTED THIS, and NO ONE is going to support anyone who tries this, because none of us use windows.

[Alfredo Canziani]

Thank you, Soumith.

Unfortunately I have the necessity of running some deep-learning on a Windows box, and I wouldn't know how to deal with it otherwise.

Perhaps using a virtual machine and streaming video data in one direction and predictions in the other or use shared memory... But all this stuff looks quite complicated.

If you have any suggestion, I would love hearing your opinion about it!

[Alfredo Canziani]

Eureka! I have Torch up and running on Windows and Cuda is working like a charm! :D

[Neil]

Hello Alfredo

Could you tell me the steps to get this done on windows ?

[Anton Varfolomeev]

Great!

Can you give others some hints?

[Arjun]

Hey

            I am a newbie in torch 7 .And i am naive in linux. Could you please suggest the steps you took to install torch and get it to work with cuda.It is really important for me at the moment.

And also is there an editor for torch ?

Thanks

Forgot to mention that i was interested in knowing the installation process for windows.

[Jonathan Tompson]

Arjun, I use the torch version of zero-brane studio by @soumith

https://github.com/soumith/zbs-torch

If you're used to Visual Studio or some other full-featured editor, then you'll be disappointed...  But it get's the job done and even has visual debugging functionality.

Thank you Jonathan.That definitely looks good.

Yup definitely.Thanks to @soumith.He has made our lives much easier.

OK, I got my inbox full of emails from all around the world. I'll post here one of the answers.

The easy way

Install 1 and 2 and enjoy.

The hard way

Building is simple in principle: take the github source (from here), run cmake (cmake-GUI for Windows) to generate project files, then compile (with Visual Studio Express 2013). But you need to fiddle with the cmake parameters to make sure all the additional libraries are recognized (blas, cuda, jpeg, etc...). This is tricky.

I am attaching my CMakeCache.txt so that you see what’s in it.

You might also need one of these, which are very hard to produce.

You also need a binary for qt-4.8, 64 bits, compiled with the same compiler. This is long to build and too large to email.

Note that https://github.com/leonbottou/torch7-custom is a fork of https://github.com/torch/torch7-distro, which was frozen when they modularized. This means code is not updated and needs merging.

[Qizhe Xie]

Hi Alfredo,

Could you please give more details about the easy way? I used torch on Linux but I am new to visual studio.

Thanks!

尊敬的Xie先生，

There is available an installer for an old version of Torch.

I highly recommend to use the Unix (Linux or Mac) version for any meaningful application.

如果您需要任何其他帮助，请联系我。

[Qizhe Xie]

I also think it's better to use Linux version because that version is deprecated. We are also investigating keras based on Theano.

谢谢！

Ihave installed Torch on windows, However I am not able to link the Cudnn package with Torch. Can you help me on that

[Simon Cheng]

Yo, the easy way 2nd link doesn't work anymore, can you repost?

[Simon Cheng]

Nvm, I found it on your server: https://leon.bottou.org/morefiles/torch/Torch7-custom-lb-7.1.1-win64.exe

[Viktoria T]

Hi Pushkar,

were you able to install the Cudnn package on windows? I would be thankful to see if and how this is achievable...

@Alfredo Canziani

I have installed Torch on Windows the "easy way".

When I start Torch, it fails with the following messages:

Try the IDE: torch -ide
Type help() for more info
Torch 7.0  Copyright (C) 2001-2011 Idiap, NEC Labs, NYU

I have looked in the specified folder,

and libtorch.dll is definitely there,

so I don't understand what is going on.

Any ideas?

[Alfredo Canziani]

Why not using PyTorch instead?

@Alfredo Canziani

Many thanks for bringing PyTorch to my attention.

I shall give it a try.
