Thanks for spotting this, is there any types that SupportsFloat supports but np.floating doesn't?

[LinHungShi]

from typing import SupportsFloat
import dataclasses
import numpy as np


@dataclasses.dataclass
class Test:
    value: float

    def __float__(self):
        return self.value


test = Test(1.0)

print(issubclass(Test, SupportsFloat)) # True

print(np.issubdtype(type(test), np.floating)) # Fals

[pseudo-rnd-thoughts]

Ok, but are you really using code that does this?

[LinHungShi]

I am expecting to have multiple rewards returned.

I thought that mo-gymnasium had its own environment checker but checking their don't
