[QE-users] Need a script that can convert primitive cell file file using conventional cell cif file

[Hung Pham]

It looks me like there is some problem with the Python interpreter in your
environment, not the code itself.
You can try to add this following line at the beginning of your python
script and rerun it:
#!/usr/bin/env python
I found a similar problem here

:
by the way, are you running it on a Window?
