I got a RPI zero W and the black/white phat.
Installed latest Raspbian Stretch Lite on to sd card with etcher.io/
Then followed the getting-started-with-inky-phat instructions.
But when trying to run the examples I get errors point to parts of the example code. see below.
Thanks for any help.
Here is the complete dump after calling: curl https://get.pimoroni.com/inky | bash
Here is the error when trying to call clean.py which is similar to trying to run any example.
