Which board/image are you using, and what code/example are you trying to follow?

It looks like you are using something that is out of date.

In latest PYNQ version, pynq.iop module was replaced and functionality is in pynq.lib now.

For v2.5 PYNQ image, you can find an example of using Pmod OLED here:
