I encountered this warning during autoneb calculation with command: mpirun -n 2 gpaw python autoneb_run.py. I found this warning will always occur when n_images > 1 in every relaxation calculation if one don't use multi nodes. I thought this might be a little bit not user-friendly... Perhaps it would be more effective to display the warning once at the start of the autoneb execution. Thanks.
