TypeError: float() argument must be a string or a number, not 'Point'

Hello, I used this a few months ago, but now it always has errors, how can I do to solve this problem?
I hope to receive your reply, thanks!

It appears you are convert an object to float.
I think you should inspect the dataframe.
