any hints ?

yes, you did an "import *", which means "bring all the names in the numpy module into this namespace. There is no name: "numpy" in the numpy module -- it's the name of the module itself. Try: import numpy numpy.__version__ then you can use the stuff in numpy this way: MyArray = numpy.array(some_stuff) Or, if you don't want to type quite so much, use something like: import numpy as N N.__version__ MyArray = N.array(some_stuff) "Namespaces are one honking great idea -- let's do more of those!" -- http://www.python.org/dev/peps/pep-0020/ -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
