what does "label" of atomic_dipole.raw refer to?

[singlebook]

Is it the dipole of each atom calculated by AIMD? DP tutorial did not make it clear.

[YWolfeee]

atomic_dipole can be any 3-dimensional vector defined in atom, and the dipole calculated by AIMD is one of that. By contrast, global_dipole is the corresponding vector defined in the system.

For example, in examples/water_tensor/dipole (devel branch), atomic_dipole is a matrix with shape nframes * (n * 3), where n is the number of atom O.
