Since numpy 1.20 the aliases np.int and np.float are deprecated (see https://numpy.org/devdocs/release/1.20.0-notes.html#using-the-aliases-of-builtin-types-like-np-int-is-deprecated). The buildin types should be used instead. Since numpy 1.24 an AttributeError exception is thrown when np.int or np.float is used.
