N2D2 Cross Compilation
moelyaagoubi opened this issue · 2 comments
After the cross-compilation from host (Ubuntu machine 18.04 x64_64) to target (NVIDIA DRIVE AGX aarch64), I was able to generate the N2D2.so file compatible with aarch64.
However when I tried to do an import with Python3 (on the target), I got segmentation fault (core dumped).
Hello,
I do not understand what you are trying to import in Python3? The N2D2.so is a C++ library.
If you want to import the Python binding, you should import the pyn2d2 module normally generated in the lib/ folder if you are using the CMake, like pyn2d2.cpython-37m-x86_64-linux-gnu.so.
However, the Python binding is currently not well documented, but stay tuned: we will release in the coming month a full Python API for N2D2!
This requiest have been fixed by mail.
The N2D2 TensorRT export is compatible with the cross-compilation NVidia environment for Drive AGX but
required some modification to the Exported Makefile.
Typically CUDA_PATH Makefile parameter should linked to the aarch64 cross-compilation CUDA environment.
