Assert the condition x > 0 holds element-wise.
tf.debugging.assert_positive( x, message=None, summarize=None, name=None ) This Op checks that x[i] > 0 holds for every element of x. If x is empty, this is trivially satisfied.
If x is not positive everywhere, message, as well as the first summarize entries of x are printed, and InvalidArgumentError is raised.
Args | |
|---|---|
x | Numeric Tensor. |
message | A string to prefix to the default message. |
summarize | Print this many entries of each tensor. |
name | A name for this operation (optional). Defaults to "assert_positive". |
Returns | |
|---|---|
Op raising InvalidArgumentError unless x is all positive. This can be used with tf.control_dependencies inside of tf.functions to block followup computation until the check has executed. |
Raises | |
|---|---|
InvalidArgumentError | if the check can be performed immediately and x[i] > 0 is False. The check can be performed immediately during eager execution or if x is statically known. |
