Omniverse Isaac Sim

Hi,
I am trying to install Isaac Sim 2021.2.1 using the Omniverse launcher. After Downloading and during the install the launcher returns the error “Error occurred during installation of Isaac Sim: stderr maxBuffer length exceeded”. The important section of the logs states:

[2022-05-20 20:28:44.685] [debug] Reset current installer.

Hi, did you solve this?

Hi @eliabntt94

I didn’t, I had to wait for the next release and that solved the error for me.

I solved by installing the suggested nvidia drivers. I was on 525.80 went back to ?.60? (I’m not at my workstation)

What you can do to debug it is commenting the last couple of lines of omni.isaac.sim.post.install.sh (omni.isaac.sim.warmup.sh especially) during installation. That is the last step, so if that script run successfully, you will have everything installed.
At that point you can manually run those commands (omni.isaac.sim.warmup.sh) and see precisely what fails.

In my case it was messing with cuda, started printing error messages, that filled python buffer, that triggered the error.
