Complex Structure Modelling invalid syntax

[aputron]

Hello!

I want to try and model a complex structure, and have tried running the given example. However, I get the following error.

Traceback (most recent call last):
  File "network/predict_complex.py", line 8, in <module>
    from RoseTTAFoldModel  import RoseTTAFoldModule_e2e

                              ^
SyntaxError: invalid syntax

I haven't been able to get into the source code very deep, but am I missing something?

Thank you for your time! -AG
