Is it possible to reuse calculated weights and sensitivity matrix to restart the inversion with new parameters (alphas, norms, bounds etc)?
Now I noticed that if SimPEG finds the created zarr-file, it will be reloaded. Is this correct?
Hi @Alexey,
Yes, you are correct. As long as you keep the data and mesh the same, then the linear forward operator will have the same shape, SimPEG will automatically re-load the zarr file and skip the sensitivity part. This is true for both potential fields (Grav/Mag), even the non-linear MVI.
If you to change the data and/or the mesh, and they happen to have the exact same dimensions (it can happen), you need to make sure to manually delete the zarr on disk.
Happy inversion.
