TypeError: Expected float, got numpy.float64 when using Float

[BrunoBelucci]

Hello,
It seems like that is an error when trying to use the Float function, more specifically due to the function:

def check_default(self, default_value: Optional[float]) -> float:
        if default_value is None:
            if self.log:
                default_value = np.exp((np.log(self.lower) + np.log(self.upper)) / 2.)
            else:
                default_value = (self.lower + self.upper) / 2.
        default_value = np.round(float(default_value), 10)

        if self.is_legal(default_value):
            return default_value
        else:
            raise ValueError("Illegal default value %s" % str(default_value))

inside class UniformFloatHyperparameter(FloatHyperparameter).
When calling np.round, a numpy.float64 is returned and the function is expecting a 'float'.
I am using configspace 0.7.2 and numpy 1.25

Downgrade configspace to version 0.7.1. It has helped me

Hiyo, thanks for the note on downgrading. Turns out it seems to be an issue with a newer version of Cython and simply downgrading Cython seems to cause other issues.

We've removed 0.7.2 from PyPI for now.

I downgraded configspace to version 0.7.1 (pip install configspace==0.7.1) to solve this problem.

This bug also appears when I use python3.11 and ConfigSpace 0.4.20, 0.4.21, 0.5.0, 0.6.0. Version 0.6.1 and 0.7.1 are fine.

The bug appeared for me in 0.7.1 (as far as mamba and pip are concerned, import ConfigSpace as cs; cs.__version__ shows 0.6.1), but I am also doing poetry shenanigans, so it could be a dependent library. Could you please elaborate, which cython version is causing the issue? I am currently on 3.0.10, but also tested with 3.0.1 to no avail.

I think I found my mistake. One of the afore mentioned shenanigans was using python 3.12.2, which has no current configspace implementation. After downgrading to 3.11.8, everything ran smoothly.

Hi,

This will be closed by #346 which removes Cython. Hopefully we can release next week.
