Describe the Bug

I'm trying to run Labelme from the command prompt with the --help argument. The command line doesn't expect output from the process, I didn't get a message that the argument is invalid. The memory of the Labelme.exe process reaches 40 megabytes, and then the it terminates. That is how it should be? I've tried --help and -h

Expected Behavior

Message like this:

Usage:
  --help         - this message
  --output       - specifies the location that annotations will be written to
  --config       - prefer to use a config file from another location
  --nosortlabels - disable to list labels in alphabetical order by default
