what is extended runtime in TensorRT

Hello guys I’m reading tensorrt’s developer’s guide in https://docs.nvidia.com/deeplearning/sdk/tensorrt-developer-guide/index.html#extending. in chapter 4: Extending TensorRT With Custom Layers, I found some custom plugin class requires extended runtime, does anybody know what it is? thank you very muchhh.


It’s just a TensorRT runtime. There is no “extended runtime” naming anymore.
It seems that the current docs are a little misleading.

You can use any of the plugin APIs (IPluginV2IOExt, or IPluginV2DynamicExt), just that IPluginV2DynamicExt is used in case for dynamic shapes.
