[darknet] build failure

[Goru1890]

Host Environment

• OS: Windows
• Compiler: VisualStudio2019BuildTools

To Reproduce
Steps to reproduce the behavior:
./vcpkg install darknet[opencv3-cuda,cudnn]:x64-windows

Fails because of this same error AlexeyAB/darknet#7533

Maybe the version of darknet in vcpkg should be updated.

Hi @Goru1890

Thanks for posting this issue.

I cannot reproduce this on my machine with Visual Studio 2017 and CUDA 11.2.

Thanks for the reply, I tried it at well with VS2017 and that worked for me, but not with VS2019.
But if I wanna try to install Qt with VS2017 it doesn't worked, it only works with VS2019.

It's a little bit annoying to uninstall and install different VS version anytime you want to install something different.

[NancyLi1013]

Yes, I will also try to confirm the result with VS2019. Thanks for your update.

@Goru1890 @NancyLi1013 @Goru1890 @cenit
Is this bug fixed in VCPKG?

[cenit]

nope, it depends on #15942 which in turn depends on AlexeyAB/darknet#7279 (which is finally ready now).
We can try to speed up things now a little bit more

[NancyLi1013]

@cenit

There is still some other work that needs to be done to fix this issue after PR #15942 merged. Is this right?

[cenit]

nope, it should be ok now

[NancyLi1013]

Thanks for your confirmation @cenit.

@AlexeyAB and @Goru1890

Could you please update vcpkg to the latest version to rebuild this?

[Goru1890]

@NancyLi1013 sorry for the late respond.

After a successful installation of darknet[opencv3-cuda,cudnn]:x64-windows, darknet is not able to use the GPU.

I think there were some architecture incompatibilities with darknet and the new rtx 3000 series, I have a 3060.

[cenit]

you need the CUDA feature to enable cuda!

darknet[cuda,cudnn,opencv3-cuda]

[cenit]

but cudnn should enable it automatically, if not that's a bug in the portfile. Let me check it later :)

[Goru1890]

you need the CUDA feature to enable cuda!

darknet[cuda,cudnn,opencv3-cuda]

config-x64-windows-dbg-err.log
I got this error

config-x64-windows-dbg-out.log

It seems like it is not found cudnn, but I followed these steps https://docs.nvidia.com/deeplearning/cudnn/install-guide/index.html.

EDIT:

But the darknet[cuda,opencv3-cuda] worked for me, darknet can now train with GPU, but I guess not with cudnn.

The above error has been fixed in PR #18005. You can update vcpkg to try this again. Please let me know if this is still a problem for you.

[cenit]

he didn't have that error but another one, which should have already been fixed days ago by #17644

is it possible that he's still using an old vcpkg version?

please @Goru1890 do a git pull

[Goru1890]

please @Goru1890 do a git pull

I always do a git pull before trying to install something with vcpkg.

[cenit]

I always do a git pull before trying to install something with vcpkg.

and also a vcpkg update && vcpkg upgrade ?

[Goru1890]

and also a vcpkg update && vcpkg upgrade ?

I didn't try that, I will try it.

[Goru1890]

[cenit]

and if you try a darknet[cudnn, ...] installation you still have the same failure?

[Goru1890]

Yes

[cenit]

can you please remove and reinstall cudnn

.\vcpkg remove cudnn
.\vcpkg install cudnn

and post full console logs about this process, and then verify if darknet still produces same error?

[cenit]

also please show output of this command

dir C:\vcpkg\installed\x64-windows\share\cudnn

[Goru1890]

.\vcpkg remove cudnn
.\vcpkg install cudnn

I removed darknet, cudnn, and opencv3

And then I runned vcpkg install darknet[cudnn,cuda,opencv3-cuda]:x64-windows again

Now it works perfectly, thanks for your help.

[cenit]

please close issue :)

[NancyLi1013]

Thanks for your help @cenit.

I'm closing this issue for now since this issue has been solved.
