Testing ACT Model in Isaac Lab Simulation

#3
by ganatrask - opened

I've been working on integrating a trained ACT (Action Chunking with Transformers) model with NVIDIA Isaac Lab to test a this dataset. I would like to initiate a discussion about performance evaluation strategies for behavior cloning models in simulation environments.

I trained an ACT model using LeRobot on the NVIDIA PhysicalAI dataset for the “panda-open-cabinet-right” task.

Currently, I am trying to use the available environment with the Franka robot in ISAAC Lab (https://isaac-sim.github.io/IsaacLab/main/source/overview/environments.html).

I have a few questions:

  1. Does anyone have experience with the integration of Isaac Lab and LeRobot?
  2. The environment is functioning correctly, and I can control the robot, but I’m struggling to get the trained model to work. I'm encountering errors related to differences in input/output dimensions and channel mismatches when loading the model.

Any insights or suggestions would be greatly appreciated!

Thanks !
