fix: issue1688 is not None to avoid the error

[quant12345]

Close #1688

When using a conditional operator on an array, an attempt is made to interpret the array as a logical value. is not None allows you to skip the logical context check.

Reproducing the error:

import numpy as np


weights = np.array([1, 2, 3])
if weights:
    pass

Closing this as the logic has changed and the issue is no longer relevant.
