If you encounter a bug in UrbanSim please: 1) first search the previously opened issues to see if the problem has already been reported; 2) If not, fill in the template below and tag with the appropriate Type label. You can delete any sections that do not apply.

Description of the bug

The urbansim/models/transition.py contains the use of np.int, which was originally deprecated in NumPy 1.20, so it cause the problem during the model run.

Data (optional)

If the issue is related to specific data please provide a link to download your data or provide an example dataset that illustrates the issue.

Environment

• Operating system:
  Mac OSX Ventura
• Python version:
  3.11
• UrbanSim version:
  3.2
• UrbanSim required packages versions (optional):

Paste the code that reproduces the issue here:

def add_rows(data, nrows, starting_index=None, accounting_column=None):
    """
    Add rows to data table according to a given nrows.
    New rows will have their IDs set to NaN.

    Parameters
    ----------
    data : pandas.DataFrame
    nrows : int
        Number of rows to add.
    starting_index : int, optional
        The starting index from which to calculate indexes for the new
        rows. If not given the max + 1 of the index of `data` will be used.
    accounting_column: string, optional
        Name of column with accounting totals/quanties to apply towards the control. If not provided
        then row counts will be used for accounting.

    Returns
    -------
    updated : pandas.DataFrame
        Table with rows added. New rows will have their index values
        set to NaN.
    added : pandas.Index
        New indexes of the rows that were added.
    copied : pandas.Index
        Indexes of rows that were copied. A row copied multiple times
        will have multiple entries.

    logger.debug('start: adding {} rows in transition model'.format(nrows))
    if nrows == 0:
        return data, _empty_index(), _empty_index()

    if not starting_index:
        starting_index = data.index.values.max() + 1

    new_rows = sample_rows(nrows, data, accounting_column=accounting_column)
    copied_index = new_rows.index
    added_index = pd.Index(np.arange(
        starting_index, starting_index + len(new_rows.index), dtype=np.int))

AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
