tf.contrib.framework.get_placeholders

Get placeholders of a graph.

tf.contrib.framework.get_placeholders(
    graph
)

For example:

a = tf.compat.v1.placeholder(dtype=tf.float32, shape=[2, 2], name='a')
a = tf.compat.v1.placeholder(dtype=tf.int32, shape=[3, 2], name='b')

tf.contrib.framework.get_placeholders(tf.compat.v1.get_default_graph())
# Returns:
#  [<tf.Tensor 'a:0' shape=(2, 2) dtype=float32>,
#   <tf.Tensor 'b:0' shape=(3, 2) dtype=int32>]

Args
graph	A tf.Graph.

Returns
A list contains all placeholders of given graph.

Raises
TypeError	If graph is not a tensorflow graph.
