torch.rb not installing torch gem on Fedora 38/ruby 3.3-preview #44

Closed jcasu closed 1 year ago

jcasu commented 1 year ago

also happening with Ubuntu 23.04/ruby 3.2.2

anyway: unpacked libtorch-cxx11-abi-shared-with-deps-2.0.1+cpu.zip under ~/local installed fresh ruby 3.3 did gem update did gem install numo-narray git cloned torch-rb did bundle config

followed the instructions you gave me, torch gem was not installed.

fwiw, things work on Mac. unlike Mac, tho, using homebrew on Linux doesn't help.

[john@fedora d.torch-rb]$ ls ~/local bin include lib libtorch share [john@fedora d.torch-rb]$ which ruby ~/local/bin/ruby [john@fedora torch.rb]$ bundle install Using rake 13.0.6 Using bundler 2.5.0.dev Using ffi 1.15.5 Using minitest 5.19.0 Using numo-narray 0.9.2.1 Using rake-compiler 1.2.3 Using rice 4.1.0 Using ruby-vips 2.1.4 Using torch-rb 0.13.2 from source at . Using torchvision 0.3.0 Bundle complete! 6 Gemfile dependencies, 10 gems now installed. Use bundle info [gemname] to see where a bundled gem is installed.

printf "hello world!\n"

require "torch" require "numo/narray"

shape = [2, 3] rand_tensor = Torch.rand(shape) ones_tensor = Torch.ones(shape) zeros_tensor = Torch.zeros(shape)

Hi @jcasu, it looks like you're cloning the repo instead of installing the gem. Try following the installation instructions in the readme, and please use Stack Overflow for additional help.

I did the bundle config/bundle install exactly like you said previously:

bundle config build.torch-rb --with-torch-dir=/home/john/local/libtorch bundle install

From the issue I posted, you can see clearly that the torchvision gem was installed by the bundle install, but the torch-rb gem on which it depends was not.

Please don't point me to the page again, because those instructions are obviously unclear to me. What steps am I missing?

thanks, -john

Hi, @jcasu. Looks like you are trying to install torch.rb from local path. Following the bundler docs , the bundler won't compile the extension: Unlike :git, bundler does not compile C extensions for gems specified as paths.

jcasu commented 1 year ago

The instructions on the site are insufficient for someone like me who is unfamiliar with gem/bundler...

Anyway I got this working:

git clone ... cd torch-rb

edit ext/torch/extconf.rb to include the directory which contains the downloaded & unpacked libtorch distro

gem build gem install --local torch-rb...gem

looks like you're making big assumptions wrt how & where the libtorch package gets unpacked.

my simple test program works, and the torchvision gem that the bundle install command installed works, too.

thanks
