\n# DeepINN

DeepINN is a deep-learning framework for solving forward and inverse problem involving PDEs using physics-informed neural networks (PINNs).

• The geometry module has been borrowed from TorchPhysics.
• TODO list.

Contribution

Create a venv in the root of the repo. Here the assumption is that the python is symlink to python3.

python -m venv .venv

Activate the environment.

source .venv/bin/activate

Confirm that the Python path is updated.

which python

The STDOUT should point to the .venv directory. Now, upgrade the pip.

python -m pip install --upgrade pip

Install the required packages.

pip install -r requirements.txt

If you want to build the docs using the same environment, then install the relevant dependencies.

pip install -r docs/requirements.txt

Testing

The testing is very simple. Just run the test.py file in the current Python virtual environment.

python test.py

Docker image

Pull the image with suitable tagname. The image is available here.

docker pull prakhars962/deepinn:tagname

CPU Only

The image opens a jupyter server by default.

docker run -p 8888:8888 prakhars962/deepinn:pre-release

You can override the jupyter server entrypoint using the following command.

docker run -it --entrypoint /bin/bash prakhars962/deepinn:pre-release

GPU passthrough

First install nvidia-docker using this guide.

Now run the container with nvidia-docker.

nvidia-docker run -it --entrypoint /bin/bash prakhars962/deepinn:pre-release

This command will bind the pwd to /workspace/tutorials and open a jupyter-lab with GPU support.

nvidia-docker run -v $(pwd):/workspace/tutorials -p 8888:8888  prakhars962/deepinn:pre-release

Alternatively, one can run interactive session.

nvidia-docker run -v $(pwd):/workspace/tutorials -it --entrypoint /bin/bash  prakhars962/deepinn:pre-release

Tagless copy

Each time you pull the updated image, docker will create a tagless copy of the old one.

The only solution is to delete them one by one using the IMAGE_ID.

docker image rm -f IMAGE_ID
