📜 XML copy support

Hello 🙋‍♀️,

• 🤔 I suggest you to add .xml file copy support according to some flag like --copy_xml to add supporting to datasets in VOC structure
• 👀 You can modify copy_files method in some way like the following:

def copy_files(files_type, class_dir, output, prog_bar, copy_xml=False):
    """Copies the files from the input folder to the output folder
    """
    # get the last part within the file
    class_name = path.split(class_dir)[1]
    for (files, folder_type) in files_type:
        full_path = path.join(output, folder_type, class_name)

        pathlib.Path(full_path).mkdir(parents=True, exist_ok=True)
        for f in files:
            if not prog_bar is None:
                prog_bar.update()
            extension = path.splitext(path.split(f)[-1])[-1].lower()
            if extension in [".jpg", ".png", ".bmp", "jpeg", "gif"]:
                shutil.copy2(f, full_path)
                if copy_xml:
                    xml_f = path.splitext(f)[0] + ".xml"
                    shutil.copy2(xml_f, full_path)

You right, fixed in 0.4.1. Use group_prefix from now on.

Set group_prefix=2 to split in groups. It should work now. Please re-open this issue if not. Thanks.
