Do you mean the QP-optimization Cartesian controller or the MoMa IK utility (based on the same controller actually)? It's difficult to tell from your stack trace what it is you're doing, but the exception is thrown during instantiation of the mjcf model, so the controller is unlikely to be the cause. By the way both modules are still running fine for me.
Yep! The QP optimization for the IK is exactly what I’m trying to use.
We now use dm_control 1.0.8
Hello, there is currently an issue when using the IK modules with dm_control==1.0.1 (error below). This is resolved by using dm_control 1.0.5. Could you please update the dependencies?
