Try it Out

For M1 macs running MacOS, there's a prebuilt binary available on the releases page. Currently, that's the only platform we have built and tested the app on. Porting to other platforms is a bit of work and we only have MacBooks for testing. If you can make the app run on Linux or Windows machines, we will happily accept your PR.

Requirements

Rust and Cargo

You can install Rust using rustup. I don't know what the MSRV is but I used v1.79.0 while building the app.

$ rustc --version
rustc 1.79.0 (129f3b996 2024-06-10)

$ cargo --version
cargo 1.79.0 (ffa9cf99a 2024-06-03)

Node and NPM

$ brew install node@20

$ node --version 
v20.14.0

$ npm --version
10.7.0

PyTorch

You can either use libtorch or provide the path to a PYTORCH installation. I found it easier to use libtorch directly.

$ wget https://download.pytorch.org/libtorch/cpu/libtorch-macos-arm64-2.2.0.zip
$ unzip libtorch-macos-arm64-2.2.0.zip

Misc Dependencies

$ brew install libomp

Building the app

• Clone the repo

$ git clone https://github.com/hedonhermdev/tune-prism && cd tune-prism

• Install npm dependencies

$ npm install

• Download the models You can use the get_models.sh script to download the models

$ ./get_models.sh

• Copy libtorch to the repo.

$ cp PATH_TO_LIBTORCH ./libtorch
$ export LIBTORCH=$(realpath ./libtorch) 

After this you're all set to start building the app.

$ npm run tauri build
$ npm run tauri dev # for development
