load libtorch2trt_dynamic.so error

[Chen-cyw]

I export the libtorch2trt_dynamic.so by "sudo python setup.py develop --plugins" and configure the trt and cuda path, but when I use the .so , it always get the error
"OSError: libtorch2trt_dynamic.so: undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameEv"
did you try and finish the whole build&load process
the "libtorch2trt_dynamic.so" I export, its size just 500kb. Then I get the "libtorch2trt.so" by the same way in the project(torch2trt) ,its size is 7.2Mb,which can load correctly

I config the setup.py like this:
def initialize_plugins_options(cmd_obj):
cmd_obj.plugins = True
cmd_obj.cuda_dir = '/home/cyw/cuda-10.2'
cmd_obj.torch_dir = None
cmd_obj.trt_inc_dir = '/home/cyw/TensorRT-7.2.1.6/targets/x86_64-linux-gnu/include'
cmd_obj.trt_lib_dir = '/home/cyw/TensorRT-7.2.1.6/targets/x86_64-linux-gnu/lib'
any other things I need to do?

Please follow these steps.
you do NOT need to change anything inside setup.py, The plugin used in this repo is amirstan_plugin.

thanks!
I want to use the converted model by mmdetection-to-tensorrt in pure tensorrt env(later in tensorrt server), Is that I just need to load the "libamirstan_plugin.so" in tensortrt ? the torch2trt_dynamic is only for convert ,not for runtime?

Yes, read this for detail.
