That's due to the change from Numeric, which is no longer supported, to
numpy, which is.
The VPython example program gas.py upon which this was probably based
was rewritten to work either with Numeric or with numpy. Similarly, the
example program stars.py (upon which nebula_20p.py might possibly be
based) has also been revised in this way.
