could not load library "libdoeye_caml" on windows

[bionicinnovations]

Torch.jl wont precompile on my Windows machine, I also updated CUDA to version 11.0:

julia> versioninfo()
Julia Version 1.4.2
Commit 44fa15b150* (2020-05-23 18:35 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: Intel(R) Core(TM) i9-8950HK CPU @ 2.90GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-8.0.1 (ORCJIT, skylake)
Environment:
  JULIA_EDITOR = "C:\Users\jason\AppData\Local\atom\app-1.49.0\atom.exe"  -a
  JULIA_NUM_THREADS = 6

I get the following error:

When I search my hard drive for "libdoeye_caml", I only find this one instance:

C:\Users\jason.julia\packages\Torch\o9HpT\src\wrap\libdoeye_caml_generated.jl:

How can I get this to work? What have I done wrong?

[truedichotomy]

I have the same issue on macOS.

[otobrzo]

I have the same on Ubuntu 20.04

[jondeuce]

Same issue on Ubuntu 18.04.4

[DhairyaLGandhi]

The torch version currently needs cuda 10.1 for torch 1.14 so maybe that is why.

PyTorch 1.15 can support newer cuda versions, so will need to update that

[freddycct]

@DhairyaLGandhi You mean Torch 1.4 and PyTorch 1.5? The latest Libtorch is 1.6.0 btw.

Yes that's right

I get similar error on Ubuntu 20.04.

[DhairyaLGandhi]

You need cuda installed in the system for that, which seems to be missing @sidml

[jondeuce]

How difficult is it to upgrade libtorch to v1.6? I would be happy to make a PR myself if someone could point me in the right direction.

[DhairyaLGandhi]

Shouldn't be too hard. We need to change the urls to the binaries with the correct cuda and cudnn here https://github.com/JuliaPackaging/Yggdrasil/blob/master/T/Torch/build_tarballs.jl

After that, hopefully, the wrappers would build easily.

[DhairyaLGandhi]

It's already present in the readme :)

[NiklasGustafsson]

This 13-month old blog post : https://fluxml.ai/blog/2020/06/29/acclerating-flux-torch.html mentions that Torch.jl assumes Linux. Is that still the case? I'm seeing this problem when I try Torch.jl on Windows.

[ToucheSir]

Yes. Windows support seems to be blocked on JuliaPackaging/Yggdrasil#1529, so CMake expertise would be welcome.
