I can't find isaac sim 2021.1.1 unity Downloads

I want to use Unity SDK with Isaac
I read Isaac Sim Docs and to download unity 3D i visited https://developer.nvidia.com/isaac/downloads
but i couldn’t find Unity for Isaac sim 2021.1.1
can i use SIM (Unity) 2020 version to Isaac sim 2021.1.1
if you answer my question thanks

Hi ,
We will be no longer support the Unity Sim, you can use the older version from the archive, which should work with 2021.1.1, but keep in mind going forward is going to be only Omniverse Isaac Sim.

Kindly,
Liila

i understand Liila super thanks for answering my question but i want to ask 2 more

when i googled about issac sim Docs there are 2 version of Docs one is “Omniverse: Isaac Sim — Omniverse Robotics documentation” the other is “Setup — ISAAC 2021.1 documentation

first one said they recommend graphic driver version 460.67 and later said 440.xx which docs is newer version? i’m really hesitate what version i will take… (i am using isaac-sim 2021.1.1)

and now i got trouble when trying reinforcement learning
i read docs and followed that i install dependency and when i type commnd like python.sh python_samples/jetbot/jetbot_train.py it worked but after 30?seconds the terminal show “omnikithelper starting” and close it self how could i solve this problem?

There was an error running python

for the first questions:

first one said they recommend graphic driver version 460.67 and later said 440.xx which docs is newer version? i’m really hesitate what version i will take… (i am using isaac-sim 2021.1.1)

please use the first one (the omniverse version) the second one is for the Isaac SDK. Yes, the latest version of Isaac Sim is 2021.1.1 and the required driver is 460.67

For the second question, I will ask one of the engineers to help you
