        Parameters
        ----------
        train_generator : class deepposekit.io.TrainingGenerator
            A deepposekit.io.TrainingGenerator class for generating
            images and confidence maps.
        n_stacks : int, default = 1
            The number of hourglass networks to stack
            with intermediate supervision between stacks
        n_transitions : int, default = -1
            The number of transition layers (downsampling and upsampling)
            in each encoder-decoder stack. If value is <0
            the number of transitions will be automatically set
            based on image size as the maximum number of possible
            transitions minus n_transitions plus 1, or:
            n_transitions = max_transitions - n_transitions + 1.
            The default is -1, which uses the maximum number of
            transitions possible.
        bottleneck_factor : int, default = 4
            The factor for determining the number of input channels
            to 3x3 convolutional layer in each convolutional block.
            Inputs are first passed through a 1x1 convolutional layer to
            reduce the number of channels to:
            filters // bottleneck_factor
        subpixel: bool, default = True
            Whether to use subpixel maxima for calculating
            keypoint coordinates in the prediction model.

        Attributes
        -------
        train_model: keras.Model
            A model for training the network to produce confidence maps with
            one input layer for images and `n_outputs` output layers for training
            with intermediate supervision
        predict_model: keras.Model
            A model for predicting keypoint coordinates with one input and one output
            using with Maxima2D or SubpixelMaxima2D layers at the output of the network.

        Both of these models share the same computational graph, so training train_model
        updates the weights of predict_model

    Parameters
    ----------
    shape : int or tuple of int
        Shape of the empty matrix.
    dtype : data-type, optional
        Desired output data-type.
    order : {'C', 'F'}, optional

        memory.

    --------

    Notes
    -----
    `empty`, unlike `zeros`, does not set the matrix values to zero,
    and may therefore be marginally faster.  On the other hand, it requires
    the user to manually set all the values in the array, and should be
    used with caution.

    Examples
    --------

        #     a temporary file save feature the save breaks functionality
        #     needs to be re-verified, since the breaks at the time the
        #     temp file is created may differ from the breaks at the last
        #     permanent save of the file.  Currently, a break introduced
        #     after a save will be effective, but not persistent.
        #     This is necessary to keep the saved breaks synched with the
        #     saved file.
        #     Breakpoints are set as tagged ranges in the text.  Certain
        #     kinds of edits cause these ranges to be deleted: Inserting
        #     or deleting a line just before a breakpoint, and certain
        #     deletions prior to a breakpoint.  These issues need to be
        #     investigated and understood.  It's not clear if they are
        #     Tk issues or IDLE issues, or whether they can actually
        #     be fixed.  Since a modified file has to be saved before it is

        #     debugger is loaded) is updated during the save, the visible

USAGE: idle  [-deins] [-t title] [file]*
       idle  [-dns] [-t title] (-c cmd | -r file) [arg]*
       idle  [-dns] [-t title] - [arg]*

  -h         print this help message and exit
  -n         run IDLE without a subprocess (see Help/IDLE Help for details)

The following options will override the IDLE 'settings' configuration:

  -e         open an edit window
  -i         open a shell window

The following options imply -i and will open a shell:

  -c cmd     run the command in a shell, or
  -r file    run script from file

  -d         enable the debugger
  -s         run $IDLESTARTUP or $PYTHONSTARTUP before anything else
  -t title   set title of shell window

A default edit window will be bypassed when -c, -r, or - are used.

[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].

Examples:

idle
        Open an edit window or shell depending on IDLE's configuration.

idle foo.py foobar.py
        Edit the files, also open a shell if configured to start with shell.

idle -est "Baz" foo.py
        Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
        window with the title "Baz".

idle -c "import sys; print(sys.argv)" "foo"
        Open a shell window and run the command, passing "-c" in sys.argv[0]
        and "foo" in sys.argv[1].

idle -d -s -r foo.py "Hello World"
        Open a shell window, run a startup script, enable the debugger, and
        run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
        sys.argv[1].

echo "import sys; print(sys.argv)" | idle - "foobar"
        Open a shell window, run the script piped in, passing '' in sys.argv[0]
        and "foobar" in sys.argv[1].
