Here you can learn about the structure and applications of Pytorch3D from examples which are in the form of ipython notebooks.
At the top of each example you can find a button named "Run in Google Colab" which will open the notebook in Google Colaboratory where you can run the code directly in the browser with access to GPU support - it looks like this:
You can modify the code and experiment with varying different settings. Remember to install pytorch, torchvision, fvcore and pytorch3d in the first cell of the colab notebook by running:
!pip install torch torchvision !pip install 'git+https://github.com/facebookresearch/[email protected]'
There is also a button to download the notebook and source code to run it locally.
