after long display update lag. Only works if `dynamic_miniters`
            or monitor thread is enabled.
        miniters  : int or float, optional
            Minimum progress display update interval, in iterations.
            If 0 and `dynamic_miniters`, will automatically adjust to equal
            `mininterval` (more CPU efficient, good for tight loops).
            If > 0, will skip display of specified number of iterations.
            Tweak this and `mininterval` to get very efficient loops.
            If your progress is erratic with both fast and slow iterations
            (network, skipping items, etc) you should set miniters=1.
        ascii  : bool or str, optional
            If unspecified or False, use unicode (smooth blocks) to fill
            the meter. The fallback is to use ASCII characters " 123456789#".
        disable  : bool, optional
            Whether to disable the entire progressbar wrapper
            [default: False]. If set to None, disable on non-TTY.
        unit  : str, optional
            String that will be used to define the unit of each iteration
            [default: it].
        unit_scale  : bool or int or float, optional
            If 1 or True, the number of iterations will be reduced/scaled
            automatically and a metric prefix following the
            International System of Units standard will be added
            (kilo, mega, etc.) [default: False]. If any other non-zero
            number, will scale `total` and `n`.
        dynamic_ncols  : bool, optional
            If set, constantly alters `ncols` and `nrows` to the
            environment (allowing for window resizes) [default: False].
        smoothing  : float, optional
            Exponential moving average smoothing factor for speed estimates
            (ignored in GUI mode). Ranges from 0 (average speed) to 1
            (current/instantaneous speed) [default: 0.3].
        bar_format  : str, optional
            Specify a custom bar string formatting. May impact performance.
            [default: '{l_bar}{bar}{r_bar}'], where
            l_bar='{desc}: {percentage:3.0f}%|' and
            r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
              '{rate_fmt}{postfix}]'
            Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
              percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
              rate, rate_fmt, rate_noinv, rate_noinv_fmt,
              rate_inv, rate_inv_fmt, postfix, unit_divisor,
              remaining, remaining_s, eta.
            Note that a trailing ": " is automatically removed after {desc}
            if the latter is empty.
        initial  : int or float, optional
            The initial counter value. Useful when restarting a progress
            bar [default: 0]. If using float, consider specifying `{n:.3f}`
            or similar in `bar_format`, or specifying `unit_scale`.
        position  : int, optional
            Specify the line offset to print this bar (starting from 0)
            Automatic if unspecified.
            Useful to manage multiple bars at once (eg, from threads).
        postfix  : dict or *, optional
            Specify additional stats to display at the end of the bar.
            Calls `set_postfix(**postfix)` if possible (dict).
        unit_divisor  : float, optional
            [default: 1000], ignored unless `unit_scale` is True.
        write_bytes  : bool, optional
            If (default: None) and `file` is unspecified,
            bytes will be written in Python 2. If `True` will also write
            bytes. In all other cases will default to unicode.
        lock_args  : tuple, optional
            Passed to `refresh` for intermediate output
            (initialisation, iterating, and updating).
        nrows  : int, optional
            The screen height. If specified, hides nested bars outside this
            bound. If unspecified, attempts to use environment height.
            The fallback is 20.
        colour  : str, optional
            Bar colour (e.g. 'green', '#00ff00').
        delay  : float, optional
            Don't display until [default: 0] seconds have elapsed.
        gui  : bool, optional
            WARNING: internal parameter - do not use.
            Use tqdm.gui.tqdm(...) instead. If set, will attempt to use
            matplotlib animations for a graphical output [default: False].
