Can you share the training script?

[Coderx7]

Hi, Thans a lot for sharing your work. really appreciate it. Can you also share the training script that was used to achieve your results? Its much appreciated.

@Davidzhangyuanhan I'd appreciate any feedback on this.

Because of the rule of the company, I can't share the training script recently. But I can explain any training details here if you ask.

Hi @Davidzhangyuanhan , thanks for your sharing research to the community. could you share more the parameter you use during training or any undescribed in the paper? however, the training results i tried is still cant compared to the result in your paper. as for now, i found still so many False Positives. Thanks

Here, we share part of our data loading pipeline code:

%%%%Transform%%%%%
        self.transform_ColorJitter= transforms.Compose([
            transforms.Resize((self.new_width, self.new_height)),
            transforms.ColorJitter(saturation = 1),
            transforms.ToTensor(),
            transforms.Normalize(mean = (0.5, 0.5, 0.5), std = (0.5, 0.5, 0.5))
           ])

def __getitem__(self, idx):
        filename =  self.metas[idx][0]
        cls = self.metas[idx][1]

        img = cv2_loader(filename)
        real_h,real_w,c = img.shape

        #Load bounding box
        assert os.path.exists(filename[:-4] + '_BB.txt'),'path not exists' + filename

        with open(filename[:-4] + '_BB.txt','r') as f:
            material = f.readline()
        try:
            x,y,w,h,score = material.strip().split(' ')
        except:
            print('[Rank' + str(self.rank) + ']' + filename)

        try:
            w = int(float(w))

            h = int(h*(real_h / 224))
            x = int(x*(real_w / 224))
            y = int(y*(real_h / 224))

            #Crop image

            else:

            if x1 + w > real_w:

            else:
