Problem in test.py

[Simpatech-app]

I ran the sh make.sh and then CC=g++ python build.py. It seems that It is building fine, however after running the test.py I have got error. Please note that in the _ext/deform_conv I have only an init.py and _deform_conv.
I really appreciate your help.

sh make.sh
CC=g++ python build.py
