def tqdm_pandas(tclass, *targs, **tkwargs):
    """
    Registers the given `tqdm` instance with
    `pandas.core.groupby.DataFrameGroupBy.progress_apply`.
    It will even close() the `tqdm` instance upon completion.

Parameters
    ----------
    tclass  : tqdm class you want to use (eg, tqdm, tqdm_notebook, etc)
    targs and tkwargs  : arguments for the tqdm instance

Examples
    --------
    >>> import pandas as pd
    >>> import numpy as np
    >>> from tqdm import tqdm, tqdm_pandas
    >>>
    >>> df = pd.DataFrame(np.random.randint(0, 100, (100000, 6)))
    >>> tqdm_pandas(tqdm, leave=True)  # can use tqdm_gui, optional kwargs, etc
    >>> # Now you can use `progress_apply` instead of `apply`
    >>> df.groupby(0).progress_apply(lambda x: x**2)
