tf.assert_positive(x, data=None, summarize=None, message=None, name=None)
Assert the condition x > 0
holds element-wise.
Example of adding a dependency to an operation:
with tf.control_dependencies([tf.assert_positive(x)]): output = tf.reduce_sum(x)
Example of adding dependency to the tensor being checked:
x = tf.with_dependencies([tf.assert_positive(x)], x)
Positive means, for every element x[i]
of x
, we have x[i] > 0
. If x
is empty this is trivially satisfied.
Args:
-
x
: NumericTensor
. -
data
: The tensors to print out if the condition is False. Defaults to error message and first few entries ofx
. -
summarize
: Print this many entries of each tensor. -
message
: A string to prefix to the default message. -
name
: A name for this operation (optional). Defaults to "assert_positive".
Returns:
Op raising InvalidArgumentError
unless x
is all positive.
