The first library to bring seamless integration between topological data analysis and deep learning on top of PyTorch. The code for Persformer will be released open-source soon together with Giotto-deep. It aims to make the day-to-day of researchers easy, allowing them to focus on inventing new models and layers rather than dealing with the more standard deep-learning code. It comes with optimized implementations for multi-GPU/TPU computations and the ability to run benchmarks and hyperparameter optimization in a few lines of code.

You can find the documentation of this repository here: https://giotto-ai.github.io/giotto-deep/

In order to analyse the results of your models, you need to start tensorboard. On the terminal, move inside the /examples folder. There, run the following command:

tensorboard --logdir=runs

Afterwards go here and, after running the notebooks of interest, you will see all the visualization results that you stored in the writer = SummaryWriter().

The simplest way to install giotto-deep is using pip:

python -m pip install -U giotto-deep

If necessary, this command will also automatically install all the library dependencies. Note: we recommend upgrading pip to a recent version as the above may fail on very old versions.

The first step to install the developer version of the package is to git clone this repository:

git clone https://github.com/giotto-ai/giotto-deep.git

The change the current working directory to the Repository root folder, e.g. cd giotto-deep. It is best practice to create a virtual environment for the project, e.g. using virtualenv:

virtualenv -p python3.9 venv

Activate the virtual environment (e.g. source venv/bin/activate on Linux or venv\Scripts\activate on Windows).

First make sure you have upgraded to the last version of pip with

python -m pip install --upgrade pip

Make sure you have the latest version of pytorch installed. You can do this by running the following command (if you have a GPU):

pip install torch --extra-index-url https://download.pytorch.org/whl/cu113

Once you are in the root folder, install the package dynamically with:

pip install -e .

The giotto-deep project welcomes contributions of all kinds. Please see our contributing guidelines for more information.

We are using pre-commit hooks to ensure that the code is formatted correctly. To install the pre-commit hooks, run the following command from the root folder:

pre-commit install

The pre-commit hooks will run automatically before each commit. If you want to run the pre-commit hooks manually, run the following command from the root folder:

pre-commit run --all-files

To run both unit and integration tests on macOS or Linux, simply run the following command from the root folder:

bash local_test.bh

I order to run your analysis on TPU cores, you ca use the following lines:

!git clone https://username:[email protected]/giotto-ai/giotto-deep
!ls
!pip uninstall -y tensorflow
!pip install -e giotto-deep/
!pip install cloud-tpu-client==0.10 https://storage.googleapis.com/tpu-pytorch/wheels/torch_xla-1.9-cp37-cp37m-linux_x86_64.whl

Once you have run the lines above, please make sure to restart the runtime.

The code will automatically detect the TPU core and use it as default to run the experiments. GPUs are also automatically supported.
