I sove it. The reason is that the tenrosr.so in trt8 is build whith gcc8.3.1. my plugin so is build with gcc4.8.5, the symbol is different with the symbol in officals. I upgrage my gcc to new version.

The symbol in trt 7.2 is _ZN8pybind116class_IN14nvcaffeparser116IPluginFactoryV2EIEE13init_instanceEPNS_6detail8instanceEPKv.local.1413
The symbo in trt 8.2. is
_ZN8pybind116class_IN14nvcaffeparser116IPluginFactoryV2EJEE13init_instanceEPNS_6detail8instanceEPKv
