I get the following error:

I see. The issue is then that the example uses an earlier version of Flux. I'm not interested in just running the example but in learning about Flux. Do you know how I can fix this error? What's the syntax I should use now for maxpool?

Thank you!

@dhairyagandhi96 I'd wait for https://github.com/FluxML/model-zoo/pull/150 to be merged.
