+    You can download the converted pb model from https://www.dropbox.com/s/qag9vzambhhkvxr/lip_jppnet_384.pb?dl=0
+    or convert the model yourself.
+
+    Follow these steps if you want to convert the original model yourself:
+        To get original .meta pre-trained model download https://drive.google.com/file/d/1BFVXgeln-bek8TCbRjN6utPAgRE0LJZg/view
+        For correct convert .meta to .pb model download original repository https://github.com/Engineering-Course/LIP_JPPNet
+        Change script evaluate_parsing_JPPNet-s2.py for human parsing
+        1. Remove preprocessing to create image_batch_origin:
+            with tf.name_scope("create_inputs"):
+            ...
+        Add
+            image_batch_origin = tf.placeholder(tf.float32, shape=(2, None, None, 3), name='input')

+            input = np.stack([image, image_rev], axis=0)
+
+        3. Hardcode image_h and image_w shapes to determine output shapes.
+           We use default INPUT_SIZE = (384, 384) from evaluate_parsing_JPPNet-s2.py.
