I print the value of(4*cnt). It actually equals to 113246208, and the type of cnt is int32. And I do not know how to solve this problem..... Could anyone tell me about it ? Thank you !

@ruiminshen not really follow the real model YOLOv2 architecture

Hi, @gengmujian10 did you check your python version? The author stated that he used python 3 so that could be the problem. I had the same issue in a similar case while unpacking some binary values and it was my wrong version of python. By the way, if you want to give it a try there is the same code but by @huseinzol05 in its github!

@huseinzol05 could you please state why do you think this is wrong? I m trying to implement YOLOv2, I already made the forward as you did but I cannot find a valid training part. Are you working on it? Thanks, Andrea

based on .cfg from darknet

[route] layers=-9

[convolutional] batch_normalize=1 size=1 stride=1 pad=1 filters=64 activation=leaky

from inference.py,

_net = reorg(passthrough)

supposed,

passthrough = slim.layers.conv2d(passthrough, 64)
_net = reorg(passthrough)

so is there a solution for this problem?

I think I encountered this problem and I believe I got around the problem by downloading and using the yolo-full.weights file stored in the Google Drive link.
