The temporary workaround is to preload the shared object 
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libnvToolsExt.so.1
Then it works normally. Maybe we missed this shared object during linking.

   * [CUDA] Correctly link against libnvtoolsext.so.1 (Closes: #1098962)
   * Generate *.shlibs to override the default dependency template.
     This makes packages built against libtorchX.Y to use the following
     dependency template:
       libtorchX.Y | libtorch-cuda-X.Y | libtorch-rocm-X.Y
   * Add .pydist files to override dependency template of python3-torch*.
     This makes packages built against python3-torch to use the following
     dependency template:
       python3-torch | python3-torch-cuda | python3-torch-rocm
   * Remove automatically generated files on clean.
