There seems to be an error in the code. The description in the first line of the parser definition is incomplete and ends with "请求失败2". This should be removed or completed with a proper description. Also, the code is missing the closing parenthesis for the argparse.ArgumentParser() function call. Here's a corrected version:

import argparse

parser = argparse.ArgumentParser(description='Process some paths.')
parser.add_argument('--input_train_path', default='', type=str, help='Root path of train.')
parser.add_argument('--input_gallery_path', default='', type=str, help='Root path of gallery.')
parser.add_argument('--input_probe_path', default='', type=str, help='Root path of probe.')
parser.add_argument('--output_path', default='', type=str, help='Root path for output.')
