@hhk7734 @eunjins @JayantGoel001 Hi I have a weight file trained using yolov4-custom.cfg file and I want to use that file during the model development but the cfg-parser is not correctly parsing the file. does it only work for the cfg files provided in your repo?

@Fetulhak Actually the issue you are facing is because the original cfg also contains code for training parameters but tensorflow-yolov4 doesn't support training. So If you just remove the training parameters from your yolov4-custom you can get it working.🙂

@JayantGoel001 thanks for your replay. here is the yolov4-custom cfg file. which layers should I have to remove?

Can you please tell me which model of yolo you are using?

I am using YOLOv4 with initial weight of yolov4.conv.137. with CSPDarkNet53 backbone

@JayantGoel001 the parser works fine now but the model is not accepting the input shape.

def make_model(self):
        K.clear_session()
        
        _input = Input(self.config.net.input_shape)
        
        self._model = YOLOv4Model(config=self.config)
        
        self._model(_input)        #error execution  of this line of code, any idea

Yes I just accessed it.

I think CFG You used for training is wrong.
1 . In your yolov4-custom.cfg file on line number 745 there is stopbackward=800 which is not part of yolov4.cfg found at AlexeyAB repo https://raw.githubusercontent.com/AlexeyAB/darknet/master/cfg/yolov4.cfg

  1. In line 891 & 992, you have updated the value of stride from 2 to 4. but In training tutorial of AI guy there is no mention of that
    https://colab.research.google.com/drive/1_GdoqCJWXsChrOiY8sZMr_zbr_fH-0Fg

Same goes for layer on line number 894.

  1. You have all values of anchor equals to 40.

I recommend you try to follow this tutorial to create custom CFG file.
https://colab.research.google.com/drive/1_GdoqCJWXsChrOiY8sZMr_zbr_fH-0Fg

Then Train the model. 🙂

@JayantGoel001 Both the cfg file and my weight files work fine when I use AlexeyAB darknet command for inference

@JayantGoel001 as alexeyab said we can change some of the values inorder to detect small objects and that is why I changed the strides and anchor box sizes.

@JayantGoel001 is that possible for your class in class UpsampleLayer(BaseLayer): to accept upsample values with stride 4. I think the problem is that class it accepts only stride of 2

@JayantGoel001 Both the cfg file and my weight files work fine when I use AlexeyAB darknet command for inference
!./darknet detector test build/darknet/x64/data/trainer.data build/darknet/x64/cfg/yolo-obj.cfg build/darknet/x64/backup/yolo-obj_2000.weights -thresh 0.075 -iou_thresh 0.3 build/darknet/x64/data/img/20170607_163916.jpg

Ya, I checked that too but the thing is I don't think a changing stride is a good option because in the training tutorial of darknet there is no mention of that.

If you want to do it
You should just clone this repo and make changes that work for you and use it in your project. 🙂

@JayantGoel001 I have solved the issue related with modified yolov4 config file by modifying the UpSampleLayer as follows. In my case, I have modified the feature concatenation layers after upsampling by modifying the strides

from tensorflow.keras.layers import UpSampling2D


class UpsampleLayer(UpSampling2D):
    def __init__(self, metalayer, metanet): 
      if metalayer.stride == 2:
        super().__init__(interpolation="bilinear", name=metalayer.name)
        self.metalayer = metalayer
        self.metanet = metanet

      else:
        super().__init__(size=(4, 4),interpolation="bilinear", name=metalayer.name)
        self.metalayer = metalayer
        self.metanet = metanet

@JayantGoel001 I got into trouble loading the weight file

/usr/local/lib/python3.7/dist-packages/yolov4/tf/utils/weights.py in _np_fromfile(fd, dtype, count)
     44         if len(data) == 0:
     45             return None
---> 46         raise ValueError("Model and weights file do not match.")
     47     return data
     48 

ValueError: Model and weights file do not match.

Looks like cfg file and weight file are not same🤔

@JayantGoel001 Thanks it was my mistake which I upload wrong weight file.

@JayantGoel001 now i have got in to another problem. When I use AlexeyAb darknet detector test command and when I use your model.inference command for the same prob_thresh=0.075 I got different prediction results. I tried a lot what the problem will be but I cannot able to solve. I have used my custom weight file trained using CSP darknet. Here are my results

Hello @Fetulhak
I think there is some difference in the accuracy of TensorFlow-yolov4 and darknet yolov4
Check this out for a better understanding. 🙂
