In my experience, the error could be caused by two things. The first reason is that you might not be giving the page enough time to load, which is why you're getting this error. I would recommend trying to add a time.sleep(5) or a similar delay before each inputs[choose].click().

The second reason could be that the button you want to click is in a second window or frame. In that case, you need to specify that this button is located in the second module. hope this works for u:)
