Error importing ExplorerHat

Hello - I’m trying to get my explorer hat working with my rasberryPi4. I Used the imager to install RaspberryPi OS (32Bit)

I’ve purchased this product if that helps:
Explorer HAT Pro - Prototyping Board for Raspberry Pi Projects – Pimoroni

I’m following the setup instructions here, and have followed all the steps:
Getting Started with Explorer HAT (

When I get to the step that says:

At this prompt you can type anything you’d normally put into a Python script. To use Explorer HAT we first need to import it, so type:

>>> import explorerhat

I get the following error message:

AttributeError: ‘AsyncWorker’ object has no attribute ‘isAlive’

I’m not sure how to proceed at this point. Does anyone know what I’ve missed, or how to fix?

Thank you

I think I’d give the example from here a try.
explorer-hat/examples at master · pimoroni/explorer-hat (

I get the same message - I think the is the same test that I was running before. Here is the output from the console:

>>> %Run
Explorer HAT Pro detected...

Ok, have a look see here, might help you sort it out.
