Which version of QuantumATK are you using? And what exactly do you get when running this script?

 I am using QuantumATK2019.12.

The error I am getting is

You have to replace

print "Temperature (default):", temperature

with

print('Temperature (default):', temperature)

The same should be done for any print in the script.

Problem remains,
Output is not spin polarized. Not getting the thermal conductance also. Getting following output. .py file attached. please rectify.
