Flambeau

Flambeau provides Nim bindings to libtorch C++ API and torchvision.

The library is not ready for general use at the moment.

Installation

The library installation including:

• auto-downloading and deploying of libtorch
• optional auto-compiling of torchvision into a shared library (if requested)

External dependencies

Initialize submodule : git submodule update --init --recursive

On Ubuntu : sudo apt-get install ffmpeg libpng-dev libjpeg-dev libzip-dev

On OpenSuse : sudo zypper install libpng16-devel libjpeg62-devel libzip-devel ffmpeg

Installation from git clone

git clone https://github.com/SciNim/flambeau

cd flambeau

nimble install or nimble develop

Note that install and develop will download and build libtorch so it may take a while.

Torchvision can now be built if desired:

nimble build_torchvision

Limitations

Compared to Numpy and Arraymancer, Flambeau inherits the following PyTorch limitations:

• No string tensors.
• No support for negative step in tensor slice (a[::-1])
  • https://github.com/pytorch/pytorch/issues/229
  • https://github.com/pytorch/pytorch/issues/604
