RWAnalyzer tour notebook complains about numpy

Code cell 7 crashes with the following stack trace:

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

Rant: once again, NumPy proves to be the most unstable package of the numeric Python stack. Not a single project of mine has not been affected by a Numpy issue over the last year.
