Windows

[luketg8]

This is a great wrapper for C# and has worked well in my Ubuntu 16.04 partition when using the tensorflow shared object.

However, I was wondering if you know if there is any way to use Bazel to compile a libtensorflow.dll so that this could work with Windows too? I saw that you said to change the name of the shared object generated to '.dll', however this seems to produce a 'BadImageFormatException' in VS2015 Windows.

Thanks in advance

PS. I am targeting x64 and .Net FrameWork 4.6.1 when building this project.

I have not build the native library on Windows, it is best to reach out on the tensorflow groups to find out how to do that.

I have only tested this stuff on MacOS.

Hi @luketg8,

Well, if you manage to get tensorflow/tensorsharp working on Windows, please update this thread. I've tried a few times over the past weekends to get it working but also never managed to get enough time to figure it out entirely.

I might give it a try again in this next weekend, though.

Regards,
Cesar

@luketg8 @cesarsouza , there are two ways to compile tensorflow. cMake and Bazel. For libtensorflow.dll , I guess it is only possible through Bazel.

@luketg8 , you stated that ./config Msys2 before Bazel, where did you face problem? During Bazel?

Hi @JimSEOW,

What happened was I did a complete Bazel install and could build the example projects from the Bazel git repo. After this, I went to my cloned TensorFlow directory, however I couldn't simply build the .dll or any example as the directory obviously has to be configured first. When I attempted to configure it asks for both the Python and the site-packages dirs. After giving these, it seems to restart the process and throw you back to the start. I know for a fact both of these directories were correct so it was confusing. I have resorted to using CMake for the time being. Also considering experimenting with the opencv dnn module (https://github.com/opencv/opencv_contrib/tree/master/modules/dnn) as they seem to have added support for tensorflow.

@luketg8 thanks for sharing. It is great for us to have a persistent guy like you. Have you feedback to whoever doing Bazel for Window? I guess they did it in a clean machine for well defined example, but not tested to compile tensorflow.

@JimSEOW thanks, it's been more out of me wanting to implement TensorFlow into the stuff I do at work, where we solely use Windows! I do however have a couple of ideas that I want to try when I get home tonight, I'll let you know how I get on. For now though, I tried the OpenCV DNN module and it worked for implementing the standard tensorflow_inception model, however it seems it will take some extra steps to implement something like the model trained through transfer learning (due to the /DecodeJPEG step) but I will again experiment and tweak and see if I can get something working!

@luketg8 Have you ever been able to run this on Windows?
My current issue is that when I run the examples, the TensorFlowSharp library throws an exception saying that the DLL 'libtensorflow' could not be found.

I'm not a python user so I don't have much clue about what bazel is or does.

If you were able to figure this out, could you please point us in the right direction?
Thanks!

@harkdev tensorflow/tensorflow#18 read this thread or #49 this for issue instructions on getting the right dll for Windows :)
