The command line is one of the three interfaces the Labelme project keeps stable, alongside the JSON annotation format and the ~/.labelmerc config format. Run labelme --help for the version installed on your machine.
Where annotations are written. A path ending in .json writes a single annotation to that file, and only one image can be annotated that way. Any other path is treated as a directory, and each annotation is named after its image.
--config
A config file path or a YAML-format string. Defaults to the user config file, ~/.labelmerc.
--reset-config
Reset window geometry and dock layout.
--version, -V
Print the application name and version, then exit.
A comma-separated list of labels, or a file containing them.
--validate-label
Label validation type. exact is the only accepted value; it rejects any label not in --labels.
--no-sort-labels
Show labels in the order supplied instead of alphabetically. Sorted is the default. The old spelling --nosortlabels is deprecated.
--flags
A comma-separated list of image-level flags, or a file containing them. Flags apply to the whole image.
--label-flags
A YAML string of per-label flags, or a file containing the equivalent JSON. Keys are regular expressions matched against the label, for example {person-\d+: [male, tall], .*: [occluded]}. The old spelling --labelflags is deprecated.
