Traceback (most recent call last):
  File "D:\environment\Anaconda\lib\logging\config.py", line 562, in configure
    handler = self.configure_handler(handlers[name])
  File "D:\environment\Anaconda\lib\logging\config.py", line 735, in configure_handler
    result = factory(**kwargs)
  File "D:\environment\Anaconda\lib\logging\__init__.py", line 1087, in __init__

    return open(self.baseFilename, self.mode, encoding=self.encoding)
OSError: [Errno 22] Invalid argument: 'D:\\workspace\\WordGCN-master\\WordGCN-master\\log\\test_run_15_06_2020_08:32:34'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "D:/workspace/WordGCN-master/WordGCN-master/syngcn.py", line 592, in <module>
    model = SynGCN(args)

    self.logger = get_logger(self.p.name, self.p.log_dir, self.p.config_dir)
  File "D:\workspace\WordGCN-master\WordGCN-master\helper.py", line 66, in get_logger
