Important notice:

This package now provides the non-cuda version (as known as the 'cpu only' build).

If you want caffe2 with cuda support, use package caffe2-cuda. This new package naming schema will better reflect the package contents. This conforms to tensorflow package naming from the official repositories.

@roachsinai The caffe2 package is for cpu-only (non-cuda) computations. So, what you're calling caffe2-cpu is actually caffe2. There is a pinned comment at the top of this page explaining this.

@dbermond thanks for your reply.

So there is caffe2 and caffe2-cude but no caffe2-cpu?

@roachsinai This is a split package that builds both caffe2 (non-cuda, cpu-only) and caffe2-cuda. That's why you see two cmake calls on the build() function.

Hi, there. As already has caffe2-cude version, why in the PKGBUILD of caffe2 still include thing like cmake -B build-cuda -S pytorch?

@petronny This is now fixed.

Please add missing dependencies.

@sleeping No need to delete caffe2 for now because python-pytorch and caffe2 are different packages. caffe2 can be used by people that want only it, without pytorch.

And pytorch does not provide the caffe2 binary executables.

caffe was merged with PyTorch

this package should probably cease to exist?

@petronny Yes, libibverbs was merged into rdma-core. Package updated.

libibverbs no longer exists in AUR now ... Should we use rdma-core?

@petronny Thank you for pointing this. Pytorch checksum updated.

Wrong hashsum for pytorch-0.4.0.tar.gz Please update it to f91c059710f802c91bed8207f2d461851b1bc2d44f7cd6e9aaa548392db9412f

PyTorch released its first stable version containing Caffe2.

Package updated to caffe2 0.8.2 from pytorch stable 0.4.0. Note that this package does not contain pytorch, but caffe2 only.

PyTorch released its first stable version containing Caffe2.

Package updated to caffe2 0.8.2 from pytorch stable 0.4.0. Note that this package does not contain pytorch, but caffe2 only.

Note: gcc5 is needed for building. Fortunately, gcc5 was moved from AUR to the [community] official repository. No need to compile gcc5 from AUR for the time being.

I have backported a patch to enable building with the newest version of 'gcc' from the official repositories (currently gcc7). Package is now building fine with gcc7.

I have added patches for building with cuda 9.1. Package is finally building fine again.

Important notes:

• gcc5 from the AUR is currently needed for building. It does not build with cuda 9.1 + gcc6 (this is a known upstream issue). Be warned that gcc5 from the AUR takes a lot of time to compile.

• The Caffe2 source code moved to PyTorch repository, but currently there is no stable version containing Caffe2 there. It is yet to be released by upstream.

• The current available stable version of Caffe2 does not have python3 support. Python3 support currently is available on the git master branch only. If you want python3 support right now, please use caffe2-git or caffe2-cpu-git packages.

@daquexian Yes, I know, but currently there is no stable release that supports python3 yet. The python3 support is present in git master only.

Unfortunately, caffe2-git (and also caffe2) currently does not compile because upstream has a nvcc issue with cuda 9.1. Details here: https://github.com/caffe2/caffe2/issues/1459 (and also here: https://github.com/caffe2/caffe2/issues/1636).

If you want python3 support for caffe2 right now, the only option is to use the package caffe2-cpu-git.

@dbermond, Caffe2 has supported Python3, https://github.com/caffe2/caffe2/issues/1720

@ricefan123 Thank you for reporting this. Now fixed.

thirdparty-protobuf-3.1.0.tar.gz check sum failed. Please fix it. Thank you.

@ricefan123 This is a known upstream issue. Currently, caffe2 does not build with CUDA 9, not even the git master version. Developers are aware.

Details here: https://github.com/caffe2/caffe2/issues/1459

Unfortunately, package is broken and we should wait for an upstream fix. If you really want to use caffe2, you'll need to downgrade CUDA to version 8.0. Otherwise, use caffe (previous generation).

Compilation error occurs again.

@bertptrs You're right! Fixed. Thank you for reporting this!

It appears that the checksum for thirdparty-protobuf-3.1.0.tar.gz is wrong. I detect it as 1176b093a05f2f4f8264d9d33f886255418af5c1007811328185f385ba6f9a7c.

cuda 8.0.61-3 fixes the glibc 2.26 issue. This package is now building fine again.

It seems that CUDA/NVCC 8.0.61 is not compatible with glibc 2.26. As a result, currently this package cannot be compiled with gpu support as it should be. Use caffe2-cpu instead (cpu-only, without gpu support) until there is a repository or upstream fix. Please leave a reply if you find a workaround.

@petronny Hi. Thank you for reporting this. I could reproduce the issue and identified the cause as being the gloo compilation, and not nccl directly. Compiling without gloo support (-DUSE_GLOO:BOOL='OFF') solves the issue. Updating the gloo commit to latest git master also solves the issue, since upstream gloo removed nccl from its third party dependencies. But another issue has just appeared: both caffe2 and gloo fails to compile with the newly released glibc 2.26. Since this glibc 2.26 issue is an unsolved upstream bug, I will update the package only after it's being solved, since it will not compile anyway for now.

I get -- Found OpenMP_C: -fopenmp (found version "4.0") -- Found OpenMP_CXX: -fopenmp (found version "4.0") -- Adding -fopenmp -- CUDA detected: 8.0 -- Automatic GPU detection failed.

@wangqr Thank you for reporting this. I can reproduce the issue. It seems that the caffe2 python dependencies have slightly changed from when I firstly checked it. I will be updating this package and the other caffe2 packages on the AUR to fix this issue.

After installed this package I tried to import it, but get the following error: Python 2.7.13 (default, Jul 21 2017, 03:24:34) [GCC 7.1.1 20170630] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from caffe2.python import workspace, model_helper Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/caffe2/python/workspace.py", line 14, i n <module> from past.builtins import basestring ImportError: No module named past.builtins >>> Installing python2-future resolves the issue.

caffe2 0.8.1 adds support for the newly released cudnn 7.0.

@petronny I have already "done something": https://aur.archlinux.org/cgit/aur.git/commit/?h=caffe2&id=894fb0890375500b0629e13ff2ad457244eaf68f That's the workaround that I could manage to do while a proper patch cannot be applied. This will require downgrade of cudnn to 6.0.21. In the meanwhile you can use caffe2-cpu, which does not have cudnn dependency.

Hi, the cudnn in [community] has been updated to 7.0.1 Please do something. The package won't be built now.

@dbermond Thank YOU! Worked just fine. :)

@pdrocaldeira Thank you for reporting it. This should be fixed as of version 0.7.0-13. All other caffe2 packages were fixed too.

Can't install. Trying -git also. Getting this error: g++-5: error: unrecognized command line option ‘-fno-plt’

@dydokamil "Currently, Caffe2 is supporting 2.7 only and python3 support is coming." https://github.com/caffe2/caffe2/issues/315 If you need python3 right now please use caffe (previous generation).

No python3? :(
