YoloV3 detects very large boxes after conversion from .weights to .pb

[YKritet]

Hi,

I used the DW2TF to convert a Yolov3 model to a .pb model, but after the conversion, the model no longer detects well.
The detected boxes' widths are all equal to the width of the input image while the heights take from the third to the whole height of the input image.
I successfully converted a model almost two months ago, it was exactly the same as the current one except for the number of classes (1 before, 7 now)

Have you ever encountered this problem? Do you have any idea how to solve it?

Thank you very much in advance

How did you get the detection? I am trying to get the detections after using DWT2F to convert yolov2 model. Please help me.

Hey @abhishek1edwin

If you have used DWT2F to convert your model then you definitely have either a .cpkt or a .pb file that represents your model.
At this point, you've got to chose to use the checkpoints (if you don't have .pb) or to convert your model to .pb which is kind-of the best format for production purposes.
What's more, Tensorflow provides (excessively) copious documentation on how to do.

it goes smth like this for quick test :

tf.reset_default_graph()
graph = tf.Graph()
sess =  tf.Session(graph=graph) 
tf.saved_model.loader.load(sess, [tf.saved_model.SERVING], "SavedModel")

then use this to determine the name of the input tensor through the operation sthat corresponds to it.

sess.graph.get_operations()

afterwards,

in_t = sess.graph.get_tensor_by_name('name of the input operation:0')
out  = sess.graph.get_tensor_by_name('name of the output operation:0')
# image = ... preprocessing
pred = sess.run( out , feed_dict={ in_t : image })

@YKritet

How do you process next. I don't know how the output is encoded. Is it possible for you to share with me the code you have implemented to get the boxes?

I output all nodes in the yoloV3-tiny net, how i get the name input node and output name,thanks
