2. labelme json to dataset: Convert label files to generate training files.

The converted files will be placed in the dataset folder and the gt folder.


Note: The file name and quantity of the image folder where the marked image is placed must be the same as the file name and quantity of the label folder of the marked file. If they are inconsistent, the training will fail and the inference will not be framed.

There are several ways of inference:

5.inference (GPU): Infer a single image.

6.inference folder (GPU): Infer the selected image folder.

7.inference api (GPU): Use web pages for image inference. After pressing the "7.inference api (GPU)" button, press the "8.inference api browser" button to open the web page.
