Hi Henry,

My guess is that you haven’t done the installation completely, because it seems it can’t find the project file.
Please check if the project file has been built and exist in the folder.

Hi ltorabi

Thanks so much,

I have completed the installation and play with UE4Editor. It take long time to download all project file in setup step.

Hi Henry,

So does your Isaac Sim now runs, or you still have some problems?

Hi Liila

I follow install guide, but i can’t run: bazel run apps/kaya_sim:joystick

Hi Henry,

Your Kaya apps should be in your SDK folder not in Isaac Sim.
Please check the instructions here:

https://docs.nvidia.com/isaac/isaac_sim/quickstart.html#kaya

In order to access the Kaya sim apps, download Kaya Sim App for Isaac SDK and extract it into the SDK folder:

tar -xvf kayasim.tar.xz -C <ISAAC_SDK_ROOT_PATH

There is no bazel on the Sim side, that is why it can not run the bazel. All the apps (Carter, Kaya, Yolo, …) should run from the SDK folder/side.

I hope this helps.
Please let me know if you still have problem running it.

Hi Liila

When I run bazel for the Kaya example, I see a black screen for the camera on Isaac Sight and bazel gives me this warning:

engine/alice/components/TcpSubscriber.cpp@156: Failed to connect to remote: Connection refused. Will try again in 0.500000 seconds.

When I Play the simulation in the Unreal Editor, I just see an empty space. The same thing happens for the Carter example.

I was wondering if you could help me.

Thank you
Behzad

Try to do as written here [url]Quick Start [Carter] in IsaacSim document don't work. - Omniverse Isaac Sim - NVIDIA Developer Forums

This is for Carter. For Kaya you need to edit other files

Hi Behzad,

Do you still have the same problem, after synching with the previous commit in the git repo?

Thanks,
Liila

Hi,
could i ask that, where did you download the kaya_sim file?
I can not find the download webpage right now?
Thanks a lot .

Hi Zhanlei,

In the recent release (2019.2) the Kaya_sim application files are part of the SDK.
Please make sure you are using the 2019.2 release.

Hope this helps,
Liila
