how do you handle graphics cards's compute capabilities? Or is it handled by the directx library?

if anyone here has experience with NuGet, please help: https://stackoverflow.com/questions/57536112/how-to-setup-a-nuget-package-to-copy-content-files-to-output-build-directory

@Nucs

Yeah, I'll dm you

Sergio Pedri

@Sergio0694

@Nucs Thanks!
As for the GPU capabilities, I query the available devices that support DX12.1, and use the first one by default.
The Gpu class also exposes all the available GPUs, so you can specifically target one in your system (or more)

Eg. if you wanted to use your secondary GPU, for instance

@henon

@Sergio0694 : I only flew over it, how about embedding the resources you need in the assembly? is that not an option?

Haiping Chen

@Oceania2018

@Sergio0694 Are you going to use computesharp to improve your neural network project?

Sergio Pedri

@Sergio0694

@henon Yeah that's my backup plan, if I can't get this to work in a while I might just move the template in a class, with the text as a constant string, and use that for now, and eventually move back to the file in the future if I can figure it out

@Oceania2018 Not right now as I'm pretty busy with university, but yeah I've thought about it.
That should give it a pretty nice performance boost , especially if I make it GPU-only so that I can keep the memory just on the GPU most of the time, and avoid havign to copy it back and forth on the CPU

Sergio Pedri

@Sergio0694

Alright, so thanks to @henon the template issue has now been fixed. Now I just need to wait for the DotNetDxc package to be updated with the new .dll files, and I'll be able to publish ComputeSharp to NuGet 👍

@Oceania2018 @moloneymb Thanks! I agree with Matthew btw, someone could learn from my code but it's something I'm just hacking together while trying to follow this python book. There are some cases where the book is not perfect, maybe the second edition has fixes? Would love feedback btw if you have free time to submit a PR :)! I'm going to keep working on the code.

I made you guys a video of a game/machine learning project that I have been working on for about a year in my free time: https://youtu.be/5kCkAW5gHEc I'm hoping to port it to TensorFlow.NET from TensorFlowSharp. Let me know what you think!

Matthew Moloney

@moloneymb

@BrendanMulcahy Looks good. I've thought about building similar games around Deep Learning. I was considering doing it in C++/OpenGL/OpenCV/Webasm.

Brendan Mulcahy

@BrendanMulcahy

I'm not much of a C++ programmer. I have tinkering around with a lot of languages but I can mainly only "do work" in C# and python

If there is anyway I can help you guys out more directly let me know. I tend to work/learn best when I'm on a mission of sorts so I can probably give the most helpful feedback if Im working on this game and using Tensorflow.NET

But I can try to lend help in other ways when I get stuck/bored and need something to switch onto for a bit

BTW, I've never really work on an open-source project, so I dont 100% know the etiquette so I might need some help with that as well (I'm open to critical feedback btw so don't feel like you need to hold anything back)

@henon

@BrendanMulcahy you are welcome to join our team if you like. don't worry, we are a friendly group of developers who are passionate about ML and you'll quickly get the hang of it. even if you only take on only a small task it would help and be very much appreciated

Brendan Mulcahy

@BrendanMulcahy

@henon Im free for most of today, anything I can tackle in about a day of work?

Meinrad Recheis

@henon

I guess the best way to build up knowledge about TF.NET which you need for most tasks is to port your game to it

Brendan Mulcahy

@BrendanMulcahy

I'm going to keep working through the book "Hands-On Machine Learning...". I'm working on a neural network right now (btw, my game uses Keras actually on top of Miguel's tensorflowsharp, so I can checkout Keras.NET too)

Meinrad Recheis

@henon

by the way, check out the examples we have

Brendan Mulcahy

@BrendanMulcahy

Yeah I check them out whenever I run into trouble :)

Meinrad Recheis

@henon

if you happen to build one that would complement our examples you might want to add it

Brendan Mulcahy

@BrendanMulcahy

BTW, the examples in the readthedocs are all super outdated

Last I checked earlier this week. I could try fixing the read the docs

Is that managed in github somehow

Meinrad Recheis

@henon

I guess it is, @Oceania2018 would know

Haiping Chen

@Oceania2018

@BrendanMulcahy Just fork repo, all the docs is in the docs folder.

Brendan Mulcahy

@BrendanMulcahy

Cool, thanks!

Haiping Chen

@Oceania2018

I’m doing the TensorFlow 2.0 in my local. But no eager mode for the first stage.

Brendan Mulcahy

@BrendanMulcahy

Do you guys prefer doing using() or the with<>(...)? I find the using more C#

Haiping Chen

@Oceania2018

We all use using for v0.11.

with<> is replaced with tf_with just for internal use.

You can use all the APIs started with tf.xxx.

Brendan Mulcahy

@BrendanMulcahy

Ok, does this work correctly then:
using (var ns = tf.name_scope(name)) { ... }

Haiping Chen

@Oceania2018

Yes, works.

Brendan Mulcahy

@BrendanMulcahy

Is there any substitute for tf.nn.in_top_k(...) ?

Eli Belash

@Nucs

gen_ops.in_top_k(...)

Brendan Mulcahy

@BrendanMulcahy

Awesome, thanks!

I didnt see it when I searched in github

Eli Belash

@Nucs

I used resharper's Ctrl+N (tick include library)

Brendan Mulcahy

@BrendanMulcahy

Good idea, although I think its bound to CTRL+T by default (search everywhere)

Meinrad Recheis

@henon

Is there any substitute for tf.nn.in_top_k(...) ?

you just found something that is missing in the tf.nn. namespace.

Brendan Mulcahy

@BrendanMulcahy

Want me to submit a PR?

Meinrad Recheis

@henon

yes please

Brendan Mulcahy

@BrendanMulcahy

SciSharp/TensorFlow.NET#353

Looks like there are flaky unit tests or something

Meinrad Recheis

@henon

what do you mean by 'flaky' ?

not enough, I would guess
