Yes, now i understand my problem, when the cmake load python, she take python 2.7 and not python 3.6.9 😦 – Found PythonInterp: /usr/bin/python (found version “2.7.17”) – Found PythonLibs: /usr/lib/aarch64-linux-gnu/libpython2.7.so (found version “2.7.17”) i changed CMakelist.txt, of Onnx , find_package(PythonInterp ${PY_VERSION} REQUIRED) - > find_package(PythonInterp 3.6.9 REQUIRED) find_package(PythonLibs ${PY_VERSION}) -> find_package(PythonLibs 3.6.9)

Now Onnx compiles fine, but with onnx-tensorrt I have an error, I think I have to change something because when I compile I have this and other errors identical: [ 47%] Building CXX object CMakeFiles/nvonnxparser.dir/builtin_op_importers.cpp.o In file included from /home/databird/Developpement/library/test/onnx-tensorrt/ImporterContext.hpp:8:0, from /home/databird/Developpement/library/test/onnx-tensorrt/ModelImporter.hpp:7, from /home/databird/Developpement/library/test/onnx-tensorrt/NvOnnxParser.cpp:6: /home/databird/Developpement/library/test/onnx-tensorrt/onnx2trt_utils.hpp: In function ‘nvinfer1::IConstantLayer* onnx2trt::addConstantScalar(onnx2trt::IImporterContext*, ScalarType, onnx2trt::ShapedWeights::DataType, nvinfer1::Dims)’: /home/databird/Developpement/library/test/onnx-tensorrt/onnx2trt_utils.hpp:105:21: error: ‘class nvinfer1::INetworkDefinition’ has no member named ‘setWeightsName’; did you mean ‘setName’? ctx->network()->setWeightsName(scalarWeights, scalarWeights.getName());

Maybe my tensorrt version (7.1.3.0). I cloned this depot https://github.com/onnx/onnx-tensorrt/tree/7.1 But it’s a other subject i think we can close this topic. Thanks for your help and your patience. Have a nice day and continue your wonderful work ! 😃

Encountered same issue while trying to build TensorRT-OSS. This issue could be resolved by a simple modification of the CMakeList.txt located here:

${TensorRT-OSS}//parsers/onnx/third_party/onnx/CMakeLists.txt

Note line 114, there is a comment like this:

# find_package Python has replaced PythonInterp and PythonLibs since cmake 3.12
# Use the following command in the future; now this is only compatible with the latest pybind11

Do what the comment said, uncomment line 116 and comment line 117 & 118:

# find_package Python has replaced PythonInterp and PythonLibs since cmake 3.12
# Use the following command in the future; now this is only compatible with the latest pybind11
find_package(Python ${PY_VERSION} COMPONENTS Interpreter Development REQUIRED)
# find_package(PythonInterp ${PY_VERSION} REQUIRED)
# find_package(PythonLibs ${PY_VERSION})

Then python3 will be picked rather than python2.
