First, I tried to restore the model as people instructed, but I could not find any clues yet. Following is my code to save the model and model was successfully saved. import tensorflow as tf from sklearn.utils import shuffle EPOCHS = 10 BATCH_SIZE = 128 x = tf.placeholder(tf.float32, (None, 32, 32, 3),name='x') y = tf.placeholder(tf.int32, (None),name='y') one_hot_y = tf.one_hot(y, 43) rate = 0.001 logits = LeNet(x) cross_entropy = tf.nn.softmax_cross_entropy_with_logits(labels=one_hot_y, logits=logits) loss_operation = tf.reduce_mean(cross_entropy) optimizer = tf.train.AdamOptimizer(learning_rate = rate) training_operation = optimizer.minimize(loss_operation) correct_prediction = tf.equal(tf.argmax(logits, 1), tf.argmax(one_hot_y, 1)) accuracy_operation = tf.reduce_mean(tf.cast(correct_prediction, tf.float32)) saver = tf.train.Saver() def evaluate(TrainX, trainLabels): num_examples = len(TrainX) total_accuracy = 0 sess = tf.get_default_session() for offset in range(0, num_examples, BATCH_SIZE): batch_x, batch_y = TrainX[offsetffset+BATCH_SIZE], trainLabels[offsetffset+BATCH_SIZE] accuracy = sess.run(accuracy_operation, feed_dict={x: batch_x, y: batch_y}) total_accuracy += (accuracy * len(batch_x)) return total_accuracy / num_examples with tf.Session() as sess: sess.run(tf.global_variables_initializer()) num_examples = len(trainImages) print("Training...") print() for i in range(EPOCHS): TrainX, trainLabels = shuffle(TrainX, trainLabels) for offset in range(0, num_examples, BATCH_SIZE): end = offset + BATCH_SIZE batch_x, batch_y = TrainX[offset:end], trainLabels[offset:end] sess.run(training_operation, feed_dict={x: batch_x, y: batch_y}) validation_accuracy = evaluate(TrainX, trainLabels) print("EPOCH {} ...".format(i+1)) print("Validation Accuracy = {:.3f}".format(validation_accuracy)) print() saver.save(sess, './lenet') print("Model saved") Training... EPOCH 1 ... Validation Accuracy = 0.765 EPOCH 2 ... Validation Accuracy = 0.911 EPOCH 3 ... Validation Accuracy = 0.933 EPOCH 4 ... Validation Accuracy = 0.958 EPOCH 5 ... Validation Accuracy = 0.965 EPOCH 6 ... Validation Accuracy = 0.973 EPOCH 7 ... Validation Accuracy = 0.978 EPOCH 8 ... Validation Accuracy = 0.986 EPOCH 9 ... Validation Accuracy = 0.985 EPOCH 10 ... Validation Accuracy = 0.980 Model saved My question is how I can use this model when I put new test data supposing that I put 5 test data to see how accurate they are when passing through in the trained model. I'd like to see the accuracy of test data and labels which will correctly fit in the trained model. Thank you for your time and I am willing to give you more details if you have things you do not understand. Continue reading...
