That line is going to break because this line

adaptation = pm.Deterministic("adaptation",
                              mu_adap[exp_idx] +
                              (adaptation_offset * sigma_adap[exp_idx])
)

creates 1 value of adaptation per participant. Asking for adaptation[participant_idx,exp_idx] still assumes you have 2 values per participant.
