[Numpy-discussion] variables not defined in numpy.random__init.py__ ?

@ Ralf.  I missed info.py at the top and it is a valid statement.

@ Brad.  My project is using Numpy and Scipy and falls over at this point when using PyInstaller.  One of the project source files has an "import random" from the Standard Library.  As you say, at this point in tempfile.py, it is attempting to "import random" from the Standard Library but instead is importing the one from Numpy (numpy.random).  How can this be fixed?  Or, is it something for PyInstaller to fix?  Thx.

    Is line 90 in __init.py__ valid?

  It is. 

In my reading of this the main problem is that `tempfile` is trying to import `random` from the Python standard library but instead is importing the one from within NumPy (i.e., `numpy.random`).  I suspect that somehow `sys.path` is being set incorrectly --- perhaps because of the `PYTHONPATH` environment variable.
