When running ``` verify.py --create-configuration-file config.py ``` this crashes with the error: ``` File "miniconda/envs/bob/bin/verify.py", line 11, in <module> sys.exit(main()) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/bio/base/script/verify.py", line 432, in main args = parse_arguments(command_line_parameters) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/bio/base/script/verify.py", line 34, in parse_arguments skips = ['preprocessing', 'extractor-training', 'extraction', 'projector-training', 'projection', 'enroller-training', 'enrollment', 'score-computation', 'concatenation', 'calibration']) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/bio/base/tools/command_line.py", line 425, in initialize args = parse_config_file(parsers, args, args_dictionary, keywords, skips) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/bio/base/tools/command_line.py", line 284, in parse_config_file create_configuration_file(parsers, args) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/bio/base/tools/command_line.py", line 578, in create_configuration_file bob.io.base.create_directories_safe(os.path.dirname(args.create_configuration_file)) File "miniconda/envs/bob/lib/python3.7/site-packages/numpy/lib/utils.py", line 100, in newfunc return func(*args, **kwds) File "miniconda/envs/bob/lib/python3.7/site-packages/bob/io/base/__init__.py", line 104, in create_directories_safe os.makedirs(directory, exist_ok=True) File "miniconda/envs/bob/lib/python3.7/os.py", line 223, in makedirs mkdir(name, mode) FileNotFoundError: [Errno 2] No such file or directory: '' ``` The issue is that `bob.io.base.create_directories_safe(os.path.dirname(args.create_configuration_file))` is called without checking whether `os.path.dirname(args.create_configuration_file)` isn't empty. There are two solutions to this issue: 1. We add this check here. 2. We correct this in `bob.io.base.create_directories_safe` and just skip empty strings. Which option would you prefer?
