IndexError due to 'ext2int.py' of 'runpf.py'

[HafizRiaz]

Dear Author, i am trying to run a repository that utilizes the PYPOWER's opf.py file to run power flow but when it calls the 'ext2int.py' to convert to continuous indexing starting from 0,it gives following error. IndexError: index 23 is out of bounds for axis 0 with size 23. if ou could help me resolve this issue, i would be thankful to you and it will assist to my phd research. Thanks for consideration.

Pypower is based Matpower of Matlab, which means it has a fatal flaw -- all indices begin from 1 rather than 0. So you have to mannually adjust it to meet Python's demand
