When I try to initialize the TCP viewer or Carter Navigation Stack operations ( bazel run packages/navsim/apps:navsim_viewer_tcp) and ( bazel run //apps/carter/navsim:navsim_navigate – --more packages/navsim/maps/warehouse.json,packages/navsim/robots/carter.json) respectively, I get the error:

I have installed TensorFlow and CUDA 10.0 as well.

I need help to view the training data when training Isaac with respective metrics as soon as possible for a research assignment. I would appreciate help… thanks!

Any update on this issue?
I have exactly the same error.

NB: if I do

locate libml_module

I’m able to find multiple libml_module.so in my system, e.g.

/home/user1/.cache/bazel/_bazel_user1/720d1ce4d0169d46a807b418dc594c19/execroot/com_nvidia_isaac/bazel-out/k8-opt/bin/packages/ml/libml_module.so

but none of them is found in the expected path described in the error message:

2019-11-26 12:12:17.892 ERROR   engine/alice/backend/modules.cpp@307: ml: /home/user1/.cache/bazel/_bazel_user1/720d1ce4d0169d46a807b418dc594c19/execroot/com_nvidia_isaac/bazel-out/k8-opt/bin/apps/carter/navsim/navsim_navigate.runfiles/com_nvidia_isaac//external/com_nvidia_isaac/packages/ml/libml_module.so: cannot open shared object file: No such file or directory

Isaac SDK would try to load the same module from several paths before giving the error message. For libml_module.so, very likely it is failing to load the module for some missing dependency shared libraries such as cuda, cudnn and tensorrt. Please check if cuda 10.0 is symlinked in /usr/local/cuda and included in LD_LIBRARY_PATH env.

I have the very similar issue, and still could not find any solution for this …

@gkobas
Please install cuda 10.0 locally and add /usr/local/cuda-10.0/lib64 to LD_LIBRARY_PATH env

Thank you so much , now it works :)

I used the following commands for those who seeks a solution :

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.0/lib64
echo ‘export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.0/lib64’ >> ~/.bashrc

then I could be able to run
bazel run //apps/navsim:navsim_navigate
