# GomalizingFlow.jl: A Julia package for Flow-based sampling algorithm
# Abstract
GomalizingFlow.jl is a package to generate configurations using the flow based sampling algorithm in Julia programming language.
This software serves two main purposes: to acceralate research works of lattice QCD with machine learning with easy prototyping, and to provide an independent implimentation to an existing code in Python/PyTorch.
GomalizingFlow.jl implements,
the flow based sampling algorithm, namely, RealNVP and Metropolis-Hastings test for two dimension and three dimensional scalar field, which can be switched by a parameter file.
HMC for that theory also implemented for comparison.
This code works not only on CPU but also on NVIDIA GPU.
# Usage (TL; DR)
```console
$ git clone https://github.com/AtelierArith/GomalizingFlow.jl && cd GomalizingFlow.jl
$ # Install Docker and GNU Make command:
$ make
$ docker compose run --rm shell julia begin_training.jl cfgs/example2d.toml
```
# Usage (detailed description)
If you're familiar with how to use Julia especially deep learning with GPU, you can setup an environment by yourself via:
```julia
julia> using Pkg; Pkg.instantiate()
julia> using GomalizingFlow
julia> hp = GomalizingFlow.load_hyperparams("cfgs/example2d.toml"; device_id=0, pretrained=nothing, result="result")
julia> GomalizingFlow.train(hp)
```
Otherwise, we recommend to create one using Docker container (see the following instructions from Step1 to Step4).
## Step1: Setup environment (using Docker)
[Install Docker, more precisely NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html#docker) and GNU Make.
Below shows author's development environment (Linux/Ubuntu 22.04).
```console
$ cat /etc/lsb-release

DISTRIB_RELEASE=22.04
DISTRIB_CODENAME=jammy
DISTRIB_DESCRIPTION="Ubuntu 22.04.2 LTS"

$ cat /etc/docker/daemon.json
{
"default-runtime": "nvidia",
"runtimes": {
"nvidia": {
"args": [],
"path": "nvidia-container-runtime"
}
}
}
```
## Step2: Build a Docker image
Just do:
```console
$ make
```
It will create a Docker image named `gomalizingflowjl`.
### Tips
If `nvidia-smi` shows `CUDA Version: 11.7`, you may want to run instead:
```console
CUDA_VERSION=11.7.0 make
```
## Step3: Start training (using Docker)
### Syntax
In general, you can train a model via:
```console
$ docker compose run --rm shell julia begin_training.jl
```
For example:
```console
$ docker compose run --rm shell julia begin_training.jl cfgs/example2d.toml # You can run in a realistic time without using GPU accelerator.
```
It will generate some artifacts in `results/example2d/`:
```console
$ ls result/example2d/
Manifest.toml evaluations.csv src
Project.toml history.bson trained_model.bson
config.toml history_best_ess.bson trained_model_best_ess.bson
```
You'll see a trained model (`trained_model.bson`), a training log (`evaluations.csv`) or configurations generated by flow based sampling algorithm (`history.bson`).
### Tips
For those who are interested in training for 3D field theory. Just run:
```console
$ docker compose run --rm shell julia begin_training.jl cfgs/example3d.toml
```
You may need run `julia -e 'using Pkg; Pkg.instantiate()'` before running `begin_training.jl`
```
$ docker compose run --rm shell bash -c "julia -e 'using Pkg; Pkg.instantiate()' && julia begin_training.jl cfgs/example3d.toml"
```
For 3D field theory parameter, you may want to use GPU for training. Make sure `nvidia-smi` command can be found from the container of `gomalizingflowjl`
```console
$ docker compose run --rm shell bash -c "nvidia-smi"
```
Some environments will produce the result below:
```console
bash: line 1: nvidia-smi: command not found
```
In this case, try `docker compose run --rm shell-gpu bash -c "nvidia-smi"` instead.
Note that `shell-gpu` refers the service name which can be found at `docker-compose.yml`.
```yml
shell-gpu:
image: gomalizingflowjl
runtime: nvidia
container_name: gomalizingflowjl-shell-gpu
volumes:
- ./:/work
working_dir: /work
command: julia --project=/work
```
## Step3-1: Watch `evaluations.csv` during training
During training, you can watch the value of ess for each epoch.
- Run training script as usual:
```console
$ docker compose run --rm shell julia begin_training.jl
```
- Open another terminal, and run the following:
```console
$ docker compose run --rm shell julia watch.jl
```
It will display a plot in your terminal something like:
```console
$ docker compose run --rm shell julia watch.jl cfgs/example2d.toml

## Step4: Analyse results
After training in Step3, you can load a trained model you specify and calculate zero-momentum
two point functions.
```julia
using CUDA, Flux, ParameterSchedulers # require to call restore function
using GomalizingFlow, Plots, ProgressMeter
backend = unicodeplots() # select backend
# You can also call `gr()`
# backend = gr()
r = "result/example2d"
# r = "result/example3d"
trained_model, history = GomalizingFlow.restore(r);
hp = GomalizingFlow.load_hyperparams(joinpath(r, "config.toml"))
lattice_shape = hp.pp.lattice_shape
cfgs = Flux.MLUtils.batch(history[:x][2000:end]);
T = eltype(cfgs)
y_values = T[]
@showprogress for t in 0:hp.pp.L
y = GomalizingFlow.mfGc(cfgs, t)
push!(y_values, y)
end
plot(0:hp.pp.L, y_values, label="AffineCouplingLayer")
```
The result should be:
```julia
julia> plot(0:hp.pp.L, y_values, label="AffineCouplingLayer")
