[Phonopy-users] ValueError: invalid literal for int() with base 10: '=2'

[Jing G. <jin...@ma...>]

Hi,

I was trying to use Phonopy to build a 2*2*2 supercell then I can do phonon calculation in VASP. I already optimized my unit cell structure, then copy CONTCAR into POSCAR, then run: phonopy -d -dim = "2 2 2" -c POSCAR_unitcell. However, I got the error which is shown below. Since I did the similar thing last week using Phonopy,  I don't know what's wrong this time and how to fix this. Very appreciate if anyone can give me a hint. Thank you very much.
