Node.js N-API wrapper for libtorch
License: Other
Not gonna lie, this repo is hella underrated. PyTorch is an excellent machine learning framework, c++ is hella fast, and the community for production it is hella small. You can bind pytorch (c++ libtorch) with golang, rust, nodejs so I'm quite impressed with ur readme.md explanation.

how can I solve and download libtorchjs??
Hi @vvmnnnkv
So as discussed before, the lib only supports float tensors and it can only converts back to JS as Uint8 array atm. It could be great to expose more types/functions and make it more generic.
In C++ I've managed to fix the issue by changing the input tensor type to 'kLong':
torch::jit::IValue input = torch::from_blob(data, shape, torch::TensorOptions().dtype(torch::kLong))
Thank you in advance and let me know if I can help in any way !
Hello! I am using your library and it is awesome. But there are new PT versions, this way lib cannot run some modern models.
Can you please make it run at least 1.8 ver?
I have tried to do it myself, but I have no idea why compilation failing all time (spend 3 days and 0 result)
Hi there,
As discussed before, there are some compatibility issue when loading a newer version of pytorch model, so it could be great if you recompile the module binaries with the latest version of libtorch.
Thank you in advance!
I made a fork that supports MacOS locally https://github.com/jlarmstrongiv/libtorchjs
To demo the fork, be sure to:
pip install torch torchvision torchaudio
https://download.pytorch.org/libtorch/cpu/libtorch-macos-1.8.1.zip
libtorch
folder as a sibling to lib
)npm --build-from-source install
Check out the changes in the binding.gyp
and add darwin
to the os
array in the package.json
. The fork is more of an example than a PR, since Iโm not quite sure how your build process works.
Would love to add support in the official package though ๐ keep up the great work!
