gcpw_optimize_width.py: AttributeError: 'numpy.float64' object has no attribute 'rint'

[biergaizi]

I was trying to run the demo gcpw_optimize_width.py, unfortunately it fails.

$ python3 gcpw_optimize_width.py 
/usr/lib64/python3.9/site-packages/numpy/core/_asarray.py:83: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray
  return array(a, dtype, copy=False, order=order)
AttributeError: 'numpy.float64' object has no attribute 'rint'

The above exception was the direct cause of the following exception:

Fixed in 6f3a3be. This is taking a long time to run and the simulation could probably use some improvements. But, that's a separate issue.
