Tensorflow: No Gradients Provided For Any Variable

I am new to tensorflow and I am building a network but failing to compute/apply the gradients for it. I get the error: ValueError: No gradients provided for any variable: ((None, t

Solution 1:

I always have the tf.nn.softmax_cross_entropy_with_logits() used so that I have the logits as first argument and the labels as second. Can you try this?
