problem: entanglement spectrum, pyalps, optim_mps

Dear All, I'm trying to use `pyalps-optim_mps` to figure out the entanglement spectrum of the AFM Heisenberg Chain. But I'm stuck. I tried setting `model['entanglement_spectra'] = '32'` in the `model_params`, but there's just no reaction at all. Can anyone tell me what I'm doing wrong and how to fix it?
