                  [--json-tree] [--graph-output OUTPUT_FORMAT]

Dependency tree of the installed python packages

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  -f, --freeze          Print names so as to write freeze files
  --python PYTHON       Python to use to look for packages in it (default: where installed)
  -a, --all             list all deps at top level
  -l, --local-only      If in a virtualenv that has global access do not show globally
                        installed packages
  -u, --user-only       Only show installations in the user site dir
  -w [{silence,suppress,fail}], --warn [{silence,suppress,fail}]
                        Warning control. "suppress" will show warnings but return 0 whether
                        or not they are present. "silence" will not show warnings at all and
                        always return 0. "fail" will show warnings and return 1 if any are
                        present. The default is "suppress".
  -r, --reverse         Shows the dependency tree in the reverse fashion ie. the sub-
                        dependencies are listed with the list of packages that need them
                        under them.
  -p PACKAGES, --packages PACKAGES
                        Comma separated list of select packages to show in the output. If
                        set, --all will be ignored.
  -e PACKAGES, --exclude PACKAGES
                        Comma separated list of select packages to exclude from the output.
                        If set, --all will be ignored.
  -j, --json            Display dependency tree as json. This will yield "raw" output that
                        may be used by external tools. This option overrides all other
                        options.
  --json-tree           Display dependency tree as json which is nested the same way as the
                        plain text output printed by default. This option overrides all other
                        options (except --json).
  --graph-output OUTPUT_FORMAT
                        Print a dependency graph in the specified output format. Available
                        are all formats supported by GraphViz, e.g.: dot, jpeg, pdf, png, svg
