   Making modifications to existing models or creating new architectures is simple, thanks to its easy-to-use message passing API, and a variety of operators and utility functions.
 - **Large-scale real-world GNN models**:
   We focus on the need of GNN applications in challenging real-world scenarios, and support learning on diverse types of graphs, including but not limited to: scalable GNNs for graphs with millions of nodes; dynamic GNNs for node predictions over time; heterogeneous GNNs with multiple node types and edge types.
-- **GraphGym integration**: GraphGym lets users easily reproduce GNN experiments, is able to launch and analyze thousands of different GNN configurations, and is customizable by registering new modules to a GNN learning pipeline.

-### Manage experiments with GraphGym
-
-GraphGym allows you to manage and launch GNN experiments, using a highly modularized pipeline (see [here](https://pytorch-geometric.readthedocs.io/en/latest/advanced/graphgym.html) for the accompanying tutorial).
-
-```
-git clone https://github.com/pyg-team/pytorch_geometric.git
-cd pytorch_geometric/graphgym
-bash run_single.sh  # run a single GNN experiment (node/edge/graph-level)
-bash run_batch.sh   # run a batch of GNN experiments, using differnt GNN designs/datasets/tasks
-```
