Multiple cutoffs
dft4py opened this issue · comments
Describe the bug
Only a single cutoff for twobody and threebody is used when multiple cutoffs are requested with whatever I try.
To Reproduce
I define multiple kernels in the Parameter helper and use twobody0, twobody1 etc to set multiple hyperparameters and cutoffs as found on the https://flare.readthedocs.io/en/latest/flare/utils/mask_helper.html page.
>>> pm = ParameterHelper(species=['C', 'H', 'O'],
... kernels={'twobody':[['*', '*'], ['O','O']],
... 'threebody':[['*', '*', '*'],
... ['O','O', 'O']]},
... parameters={'twobody0':[1, 0.5, 1], 'twobody1':[2, 0.2, 2],
... 'threebody0':[1, 0.5], 'threebody1':[2, 0.2],
... 'cutoff_threebody':1},
... constraints={'twobody0':[False, True]})
>>> hm = pm.as_dict()
>>> kernels = hm['kernels']
>>> cutoffs = hm['cutoffs']
Expected behavior
I expected this to make multiple cutoffs for twobody and threebody
I can confirm that I saw the same as you. working on this now.
in fact, the code should be right. The twobody_cutoff_list
contains multiple cutoffs. Please use the mask as suggested in the tutorial: https://flare.readthedocs.io/en/latest/flare/kernels/mc_sephyps.html
Is it possible for you to supply an example of this? I am still unable to get this to work. Say I have the following structure. How do I go about assigning one cutoff / hyperparameter set to C-C interactions and a different cutoff / hyperparameter to all other interactions? I cannot find a good example page to work from.
