Tensorflow: How to feed a placeholder variable with a tensor?

Question

I have a placeholder variable that expects a batch of input images:

input_placeholder = tf.placeholder(tf.float32, [None] + image_shape, name=\'input_images         


        

Answer 1

This works for me in latest version...maybe you have older version of TF?

a = tf.Variable(1)
sess.run(2*a, feed_dict={a:5}) # prints 10
