Could not find NVML during CMake on a Jetson Orin (iGPU)

Environment

• Ubuntu 20.04
• Jetson AGX Orin32 Gb
• Cuda 11.4

Problem

While making cmake to build N2D2 :

CMake Deprecation Warning at CMakeLists.txt:20 (cmake_minimum_required):

  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell

I think the problem comes from the integrated GPU (iGPU) used in the Jetson. There's no nvidia-smi command nor nvml library.

Is there a way to bypass this error ? For example by replacing nvml by jetson-stats to use equivalent monitoring tools for GPU, CPU, Mem, swap, Disk usage, Power, clocks, etc

Hi @Veccoy,

I think your problem comes from pybind11. N2D2 needs this module to compile its Python API and it seems it cannot find the CMakeLists.txt of this submodule.

Can you run this command

git submodule update --remote

and restart the compilation of N2D2 in your environment ?

Hi! Thank you for your answer @vtemplier

After git submodule update --remote the error is the same. I've copied PyBind11 github repo into the folder ./third_party/pybind11 and it's working
