Can I write a Custom Layer Using Python ?

I can’t find a sample that write a Custom Layer Using Python from the TensorRT developer documentation.But there is the Plugin interface from the python api https://docs.nvidia.com/deeplearning/sdk/tensorrt-api/python_api/infer/Plugin/IPluginV2Ext.html, Does that mean I can write a Custom Layer Using Python ?

Please reference https://docs.nvidia.com/deeplearning/sdk/tensorrt-developer-guide/index.html#add_custom_layer_python
