Looks like you have a circular import, and Python doesn't like them. Sorry,
I don't have a quick hack solution to this, all I can propose is to look at
import chain, understand, which import breaks it all, and get rid of it.
For example, you can move some imports into functions, so they're not
called at the module initialization time.
