Modulus Symbolic (Modulus Sym) provides an abstraction layer for using PDE-based symbolic loss functions. Additional information can be found in the Modulus documentation. Users of Modulus versions older than 23.05 can refer to the migration guide for updating to the latest version.
The recommended method for installing the latest version of Modulus Symbolic is using PyPi:
pip install nvidia-modulus.symThe recommended Modulus docker image can be pulled from the NVIDIA Container Registry:
docker pull nvcr.io/nvidia/modulus/modulus:23.05For a local build of the Modulus Symbolic Python package from source use:
git clone git@github.com:NVIDIA/modulus-sym.git && cd modulus-sym
pip install --upgrade pip
pip install .To build release image, you will need to do the below preliminary steps:
Clone this repo, and download the Optix SDK from https://developer.nvidia.com/designworks/optix/downloads/legacy.
git clone https://github.com/NVIDIA/modulus-sym.git
cd modulus-sym/ && mkdir depsCurrently Modulus supports v7.0. Place the Optix file in the deps directory and make it executable. Also clone the pysdf library in the deps folder (NVIDIA Internal)
chmod +x deps/NVIDIA-OptiX-SDK-7.0.0-linux64.sh
git clone <internal pysdf repo>Then to build the image, insert next tag and run below:
docker build -t modulus-sym:deploy -f Dockerfile --target deploy .Alternatively, if you want to skip pysdf installation, you can run the following:
docker build -t modulus-sym:deploy -f Dockerfile --target no-pysdf .For guidance on making a contribution to Modulus, see the contributing guidelines.
