Python-asynchronous progressbar widgets for use in Jupyter/IPython in conjunction with ipywidgets
A small package that provides an python-asynchronous progressbar widgets for use in Jupyter/IPython in conjunction with
Many times, when building a small dashboard on IPython there are functions that take some time to be executed but cannot be split into chunks, in the middle of which we could update a progress bar.
Since we want to give the user feedback that we are actually doing something and now he has to wait for a little, we can simply display the prototypical
However for some (most?) functions we may actually have a rough estimate of the time of wait and can make the wait a little more visual with a progressbar!
The progressbar needs to be updated (filled) while python is working on other things. Therefore, we can use a python thread to update the value of the progressbar. That way, our main python process can take care of other code meanwhile.
# Create the progress bar object (not the widget) my_progressbar = AsyncProgressBar(time=2, description='Loading dataset:') # Return the widget for display my_progressbar.display() # ... # Trigger the progressbar my_progressbar.run()
The object also has a
close() method (and its inverse
reopen()), for hiding the progressbar whenever we want:
my_progressbar.run() function_that_takes_long() my_progressbar.close(on_finish=True) # or set close_on_finish=True on creating the progressbar object
However,for a typical use case in which we just want a temporal progressbar, we can specify the
close_on_finish on creation:
# Create the progress bar object (not the widget) my_progressbar = AsyncProgressBar(time=2, description='Loading dataset:', close_on_finish=True) # ... # Trigger the progressbar my_progressbar.run() # when done the progress bar will hide
