I will tell what I have done:
First, I download onnx-tensorrt from "https://github.com/onnx/onnx-tensorrt";
to my /home dir, but in this project, the onnx-tensorrt/third_party/onnx/
directory is empty, I download the onnx from
"https://github.com/onnx/onnx/tree/553df22c67bee5f0fe6599cff60f1afc6748c635"; to
the onnx-tensorrt/third_party/onnx/ dir.
Then I follow the onnx-tensorrt official tutorial, do the compile:
cd onnx-tensorrt
mkdir build && cd build
cmake .. -DTENSORRT_ROOT=<path_to_trt> && make -j
// Ensure that you update your LD_LIBRARY_PATH to pick up the location of
the newly built library:
export LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH
It can compile correctly , but I found nothing like named libonnx.so**. And
when I compile the mxnet with -DTENSORRT=1, It reported error again.
You said I must define some arguments , how many arguments should I have to
define?
Now I have the mxnet-src file in my home directory like :
/home/$USER_NAME/mxnet-src
and onnx-tensortrt in my home dir: /home/$USER_NAME/onnx-tensorrt
and onnx in the onnx-tensorrt directory
:/home/$USER_NAME/onnx-tensorrt/third_party/onnx/
How should I define the eviron arguments? You said I must follow the .sh
file in the docker file, but I'm not sure how many arguments I shoud to
define. Some args like ONNX_NAMESPACE, LIBRARY_PATH, LD_LIBRARY_PATH,
CPLUS_INCLUDE_PATH, CXXFLAGS, should I have to define it manually? And the
popd, pushd, should I have to do that like the .sh file did?
I'm not very good at do compiling and define args, so thanks for your
answering!!
