    was demoing an RL env where models have to recover a black-box hamiltonian (often non-physical) from expectation values.

    was demoing an RL env where models have to recover a black-box hamiltonian (often non-physical) from expectation values. a researcher at a frontier lab asked an interesting question, if they’re just using a python sandbox to fit data points why are the failure rates so high?
