tf.compat.v1.raw_ops.CheckNumerics
tf.raw_ops.CheckNumerics(
tensor, message, name=None
)
When run, reports an InvalidArgument error if tensor has any values
that are not a number (NaN) or infinity (Inf). Otherwise, returns the input
tensor.
Example usage:
a = tf.Variable(1.0)
tf.debugging.check_numerics(a, message='')
b = tf.Variable(np.nan)
try:
tf.debugging.check_numerics(b, message='Checking b')
except Exception as e:
assert "Checking b : Tensor had NaN values" in e.message
c = tf.Variable(np.inf)
try:
tf.debugging.check_numerics(c, message='Checking c')
except Exception as e:
assert "Checking c : Tensor had Inf values" in e.message

message
|
A string. Prefix of the error message.
|
name
|
A name for the operation (optional).
