Numerical SOAP derivatives for periodic systems

Nilsgoe opened this issue · 6 comments

Hi,
as mentioned in issuer #95, for deriv , desc = soap.derivatives(mol, ... ) the option of calculating SOAP derivatives for periodic systems periodic = True is currently not available. I would be interested in this option and hoped it could be added in the future.

Hi,
Thank you for the suggestion. We will see what we can do, and try to get back to you in a few weeks.

We have made a plan to implement soap derivatives, both numerical and analytical, on periodic systems (with some constraints). We will make an effort to finish it by the end of this year.

Hi,
I want to train the nn potential to predict energy and force for materials. However, when periodic = True, and the derivatives are not realized. So, I hope the derivatives can be applied for materials in the future

Hey, would it be possible to use numerical derivatives for periodic systems if the lines 706 - 709 are deleted? I had tried it, and it worked, but I am not sure if I am not missing something

Could you try installing directly from branch v2.0.0? The numerical derivatives for periodic systems are implemented there, and will be made into a new release soon.

Now available in v2.0.0
