[python #JYK-434092]: Error running radiosonde plotting script from tutorial

Greetings,

Apologies for the delayed response.

This error should be fixed with Cartopy >= 0.19, so make sure you're running 
the latest cartopy.

Cheers,

Ryan

> `np.float` was a deprecated alias for the builtin `float`. To avoid this

> `np.float64` here.
> The aliases was originally deprecated in NumPy 1.20; for more details and
