Dear guodonglin:
Could you show me the full outputs of nscf.out and epw.out with the inputs of nscf.in and epw.in?
Sincerely,

Dear guodonglin:
You are using the old version of EPW v.4.0.0 and it is difficult for me to keep track of the origin of your issue.
Could you try to use the recent version of EPW (v5.4) and confirm that you still encounter the issue?
Sincerely,
