Train loss and Validation loss are very high!! about ssd_tensorflow_traffic_sign_detection HOT 7 OPEN

@Jasonsun1993
Problem solved， I changed the learning rate of training to 0.5 (original code use the default 0.01,which is very small considering training from scratch):
OPT = tf.train.AdadeltaOptimizer()
change to
OPT = tf.train.AdadeltaOptimizer(learning_rate=0.5)

I have the same problem. The trainning loss at beginning is over 800, and so as the validation loss. And after about 20000 round training, it drop to about 200.

I did some edit to some api, so it can train under tensorflow1.4.1 . Besides this, nothing changed.

@xinxueying After training, did you test the images in samples_images folder? Did it have good results?

@xinxueying Really? Did you train the whole data set?? How about the results?? Besides, can I have your Wechat number? I want to discuss about this code further.

Have you got the dataset? I can't open the link LISA Traffic Sign Dataset(http://cvrr.ucsd.edu/LISA/lisa-traffic-sign-dataset.html). If you got the dataset, could you please send it to me?

@xinxueying what is the val loss when u ended training?
