train my own dataset, the format of label

[ssunlin]

hello,@avanetten
I want to train my own dataset, but I don't want to download the COWC dataset because of big size. I wonder what's the format of labels when executing the yolt2 model.
my dataset format is like this:
images/0.jpg
images/0.txt (the label in txtfile is :cls_id, x, y, w, h )
when I execute the yolt2 model, it looks normal, while the accuracy, precision and recall is NAN. So I want to know what's the label format in the txtfile.

I guess you are running out of images for training. It looks like you have 623 images, and this NaN problem start right after epoch 623.

Hello! How you change the your datasets to the net work needed?I having been puzzled this questions for a long time and did not find any way to work it out.

Hi @sunyuxiu
Have you found solution?

[sunyuxiu]

@edwardnguyen1705 Yes,it is maybe need the picture and the list name of picture,the bounding boxes of yolo format also needed.Which step do you on?Training or testing?

[edwardnguyen1705]

@sunyuxiu I already prepared anything. But my image size is 320x320 (actual size 1600x600, but I cropped patches 320x320, and transform the box coordinates to 320x320). I trained yolov5 on this dataset, there is no problem.

@edwardnguyen1705 yolov5 can support the hug size of image?My image size is hug with 8000x6000 and the object is so small with around 10x30.With a lot of days of searching for the properly net work and find this net can support the hug size.But recently I meet a new error with this net work when testing.#101 you look and help me?

[sunyuxiu]

@edwardnguyen1705 Now I am trying training the image under the format of tensorflow and building the docker.Do you have an good idea about the training the hug size of image as I mentioned above?yolo v5 or this net?

@sunyuxiu ,
I have not tried this one so I do not know. But yolov5 is not suitable for your task, it cannot detect multi-scale objects in an image.
