# Description

Ever since we upgraded the torch version from 2.0.1 (in Isaac Sim
2023.1.1) to 2.2 (in Isaac Sim 4.0), we have seen some of the tests
(such as `test_articulation.py`) fail due to improper deinitialization
of the created class.

This MR fixes this issue by creating a dummy tensor inside the
`SimulationContext` in Isaac Lab. While this is a hack, it is effective
and helps alleviate the problem. It is hard to figure out the root cause
without really understanding what changed on the torch side.

Fixes #639
