示例1: gisnan

# 或者: from numpy.core import isnan [as 別名]
def gisnan(x):
"""like isnan, but always raise an error if type not supported instead of
returning a TypeError object.
Notes
-----
isnan and other ufunc sometimes return a NotImplementedType object instead
of raising any exception. This function is a wrapper to make sure an
exception is always raised.
This should be removed once this problem is solved at the Ufunc level."""
from numpy.core import isnan
st = isnan(x)
if isinstance(st, type(NotImplemented)):
raise TypeError("isnan not supported for this type")
return st
