TensorFlow function to check whether a value is in given range?

问题

I know there is tf.greater(x,y) which will return true if x > y (element-wise). Is there a function that returns true if lower_bound < x < upper_bound (element-wise) for a tensor x?

回答1:

There's not a specific function for that, but you can use a combination of tf.greater, tf.less, and tf.logical_and to get the same result.

lower_tensor = tf.greater(x, lower)
upper_tensor = tf.less(x, upper)
in_range = tf.logical_and(lower_tensor, upper_tensor)
