示例1: gisfinite
# 需要導入模塊: from numpy import core [as 別名]
# 或者: from numpy.core import errstate [as 別名]
def gisfinite(x):
"""like isfinite, but always raise an error if type not supported instead of
returning a TypeError object.
Notes
-----
isfinite 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 isfinite, errstate
with errstate(invalid='ignore'):
st = isfinite(x)
if isinstance(st, type(NotImplemented)):
raise TypeError("isfinite not supported for this type")
return st 示例2: gisinf
# 需要導入模塊: from numpy import core [as 別名]
# 或者: from numpy.core import errstate [as 別名]
