This package provides a library of functions useful for neural networks, such as softmax, sigmoid, batched multiplication, convolutions and pooling. Many of these are used by [Flux.jl](https://github.com/FluxML/Flux.jl), which loads this package, but they may be used independently.

For use with automatic differentiation, this package defines gradients using [ChainRules.jl](https://github.com/JuliaDiff/ChainRules.jl). These will be seen by various packages including [Zygote.jl](https://github.com/FluxML/Zygote.jl).

GPU support is provided as package extensions (see the `ext/` folder). In order to load the extensions, use the imports
```julia
using NNlib, CUDA, cuDNN
```
for CUDA support, or
```julia
using NNlib, AMDGPU
```
for AMDGPU support.
