How to solve teh problem " Error in routine prtmob (1): The carrier density is 0"

I use the "dipole_sp" to calculate the transport of graphene, but i see the problem in epw2.out, i do not know how to solve it.

Hi guodonglin,

I encountered the same error. Could you explain how you resolved it?

Thanks,
