tf.placeholder_with_default caused to error

Short question. Why caused this line to error? : 

x = tf.placeholder_with_default([0.0 for _ in range(784)], [None, 784], name='images')

How can I fix it? Thanks in advance.

This error occurs: 

ValueError: Shapes must be equal rank, but are 1 and 2 for 'images' (op: 'PlaceholderWithDefault') with input shapes: [784].

The problem is you make shape [None, 784] for the placeholder, but default value has shape [784]. So just add one more square bracket around default value, like:

x = tf.placeholder_with_default([[0.0 for _ in range(784)]], [None, 784], name='images')

So you have shape of [1,784]
