dpgen simplify for transfer learning

[alikhamze]

Hello,

I am trying to use the simplify function of dpgen for transfer learning, as this document says is possible.

I set up my simplify.json following the examples here and here, with the change that for the new, transfer-learned model, I changed the type map to replace the old element with the new element.

When I run simplify, I get the following error: AssertionError: size of fp_pp_files should be the same as the size of type_map from line 2989 in run.py.
This is because simplify overrides the type map in the parameter file and adds the old species to the type map, and then crashes because I have not added the old species' POTCAR to the simplify input file.

How can I set up my parameter file for transfer learning? Do I need to add the old POTCAR to the parameter file? I think doing so would fix the error, but it's not clear to me that the transfer learning would proceed as I want it to if I do...

Thank you!

There are two type_map parameters in the file. Did you only change one?

@njzjz both have been updated to the desired type map.

@njzjz i've attached my input file, do you see any other possible errors? Thank you.

May I ask if the problem has been resolved? I have also encountered the same problem

It will be helpful if you could print those two values.
