Hi  ShaoFei Wang,

It looks like you do not have an interatomic force constant file (file name
should be ifc.q2r) saved in the 'save' directory where you have dyn and
dvscf files.

For the EPW related problems, I would recommend posting on
https://forum.epw-code.org/ and an expert will definitely help you out.

Best,
