How to get the file “uspto_expansion.onnx”,"uspto_templates.csv.gz" and "zinc_stock.hdf5"

After I read the docs, I still don't know How to run the code successfully
```app = AiZynthApp("/path/to/configfile.yaml")```.
especially, I don't know how to  get the “uspto_expansion.onnx”,"uspto_templates.csv.gz" and "zinc_stock.hdf5", which was written in the configuration file. Could you give me a demo file ,so that I can run all the function(or demo) about aizynthfinder's demo. thanks u!!!
