Training does not work about tensorflow-vgg

Hi @martin3000, it depends on how you train the network. Do you mind to let me have a look at your script that trains the network?

Of course...have a look. I forgot to normalize the image: img1 = img1 / 255.0.
I changed the cost function and now training works:

    cross_entropy  = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(labels=true_out, logits=vgg.prob))
    train = tf.train.GradientDescentOptimizer(0.5).minimize(cross_entropy)
