Describe

This PR enhances the amgnet_cylinder example by adding model export and Python inference functionalities, aligning it with deployment standards for practical applications.

The main changes include:

1. examples/amgnet/amgnet_cylinder.py:

   • Implemented an export() function to save the trained model in a static graph format for inference.
   • Implemented an inference() function to load the exported model and perform predictions.
   • Updated the main() function to orchestrate the new export and infer modes based on the configuration file.

2. examples/amgnet/deploy/python_infer/amgn_predictor.py:

   • Introduced a new custom predictor class, AMGNPredictor.
   • This is necessary to handle the specific pgl.Graph input data type required by the AMGNet model, which is not supported by standard predictors.

3. examples/amgnet/conf/amgnet_cylinder.yaml:

   • Added a new INFER section to centralize all configurations for the model export and inference processes.

4. Documentation (docs/zh/examples/amgnet.md):

   • Consolidated the amgnet_cylinder documentation into the main amgnet.md file.
   • Deleted the standalone examples/amgnet/amgnet_cylinder.md file.
   • Added a new, detailed section with instructions and command examples for running model export and inference.
