hyperspy.external.progressbar module

hyperspy.external.progressbar.progressbar(*args, **kwargs)

Uses tqdm progressbar. This function exists for wrapping purposes only. Original docstring follows: —————————————-

Decorate an iterable object, returning an iterator which acts exactly like the original iterable, but prints a dynamically updating progressbar every time a value is requested.

iterable : iterable, optional
Iterable to decorate with a progressbar. Leave blank to manually manage the updates.
desc : str, optional
Prefix for the progressbar.
total : int, optional
The number of expected iterations. If unspecified, len(iterable) is used if possible. As a last resort, only basic progress statistics are displayed (no ETA, no progressbar). If gui is True and this parameter needs subsequent updating, specify an initial arbitrary large positive integer, e.g. int(9e9).
leave : bool, optional
If [default: True], keeps all traces of the progressbar upon termination of iteration.
file : io.TextIOWrapper or io.StringIO, optional
Specifies where to output the progress messages (default: sys.stderr). Uses file.write(str) and file.flush() methods.
ncols : int, optional
The width of the entire output message. If specified, dynamically resizes the progressbar to stay within this bound. If unspecified, attempts to use environment width. The fallback is a meter width of 10 and no limit for the counter and statistics. If 0, will not print any meter (only stats).
mininterval : float, optional
Minimum progress display update interval, in seconds [default: 0.1].
maxinterval : float, optional
Maximum progress display update interval, in seconds [default: 10]. Automatically adjusts miniters to correspond to mininterval after long display update lag. Only works if dynamic_miniters or monitor thread is enabled.
miniters : int, 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, optional
If unspecified or False, use unicode (smooth blocks) to fill the meter. The fallback is to use ASCII characters 1-9 #.
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 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}, ‘

Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
percentage, rate, rate_fmt, rate_noinv, rate_noinv_fmt, rate_inv, rate_inv_fmt, elapsed, remaining, desc, postfix.

Note that a trailing “: ” is automatically removed after {desc} if the latter is empty.

initial : int, optional
The initial counter value. Useful when restarting a progress bar [default: 0].
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.
gui : bool, optional
WARNING: internal parameter - do not use. Use tqdm_gui(…) instead. If set, will attempt to use matplotlib animations for a graphical output [default: False].

out : decorated iterator.
