Install a full PyG environment using only a single pip command

[Anjum48]

😵 Describe the installation problem

The current installation process requires installing PyTorch first then running a second pip install for all the PyG components. This is because torch is required in the setup of the PyG components:

• Cannot install torch-geometric via requirement.txt #861
• How can I install torch_geometric in remote server without manually do it. #1440

There are cases where only a single pip command using requirements.txt can be used to set up the full env, for example the following frameworks for queuing jobs:

• https://clear.ml/docs/latest/docs/apps/clearml_task
• https://docs.wandb.ai/guides/launch/create-launch-job#requirements-file

Is there a way of setting up a full Python environment for PyG using a single pip command?

Environment

• PyTorch version:
• OS:
