Isaac SDK sample run error(

I dowloaded isaac sdk 2020.2 and tried to bazel run the sample in 'bazel run //apps/navsim:navsim_navigate
', but there was an error.

it throws the problem:

Analyzing: target //apps/navsim:navsim_navigate (0 packages loaded, 0 targets configured)

Here is my workstation spec and version:
GPU : RTX2080ti
CUDA : 10.2
Nvidia graphic card driver :440
bazel : 3.1.0

IsaacSim Unity3D game mode also run well with ‘./sample.x86_64 --scene small_warehouse -logFile -’.

How can I fix this problem?

The log seems to indicate that Bazel was fetching Cuda 10.2 libraries to build and was interrupted somehow (network connectivity, disk space exhausted, errant keystroke?). Is this consistently happening on retries?

You may want to check that you’ve run the install_dependencies.sh script first.

Next, you could try clearing Bazel’s cache bazel clean --expunge and building again.

I downloaded cuda deb file(ver 10.2) and waited about 3min, and it worked.

However, I’ve faced another error like this :

Segmentation fault (core dumped)

I already installed the dependency with ‘engine/build/scripts/install_dependencies.sh’

How can I fix this error ?

I solved this problem with this code:

-laptop:~/isaac/sdk$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.2/lib64
-laptop:~/isaac/sdk$ echo ‘export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.2/lib64’ >> ~/.bashrc

Tnx !
