The 🔥 Deep Learning Framework

Installation

import Pkg
Pkg.add("Lux")

Getting Started

using Lux, Random, Optimisers, Zygote
# using LuxCUDA, LuxAMDGPU # Optional packages for GPU support

# Seeding
rng = Random.default_rng()
Random.seed!(rng, 0)

# Construct the layer
model = Chain(BatchNorm(128), Dense(128, 256, tanh), BatchNorm(256),
              Chain(Dense(256, 1, tanh), Dense(1, 10)))

# Get the device determined by Lux
device = gpu_device()

# Parameter and State Variables
ps, st = Lux.setup(rng, model) .|> device

# Dummy Input
x = rand(rng, Float32, 128, 2) |> device

# Run the model
y, st = Lux.apply(model, x, ps, st)

# Gradients
gs = gradient(p -> sum(Lux.apply(model, x, p, st)[1]), ps)[1]

# Optimization
st_opt = Optimisers.setup(Optimisers.Adam(0.0001), ps)
st_opt, ps = Optimisers.update(st_opt, ps, gs)
