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')
2. Create input
image = cv2.imread(path/to/image)
image_rev = np.flip(image, axis=1)
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.
parsing_out1 = tf.reduce_mean(tf.stack([tf.image.resize_images(parsing_out1_100, INPUT_SIZE),
tf.image.resize_images(parsing_out1_075, INPUT_SIZE),
tf.image.resize_images(parsing_out1_125, INPUT_SIZE)]), axis=0)
Do similarly with parsing_out2, parsing_out3
4. Remove postprocessing. Last net operation:
raw_output = tf.reduce_mean(tf.stack([parsing_out1, parsing_out2, parsing_out3]), axis=0)
Change:
parsing_ = sess.run(raw_output, feed_dict={'input:0': input})
5. To save model after sess.run(...) add:
input_graph_def = tf.get_default_graph().as_graph_def()
output_node = "Mean_3"
output_graph_def = tf.graph_util.convert_variables_to_constants(sess, input_graph_def, output_node)
output_graph = "LIP_JPPNet.pb"
with tf.gfile.GFile(output_graph, "wb") as f:
