I just installed the pmw widgets package using the included setup.py into my python 2.7.13 site-packages folder. when I try to import pmw from a python console prompt, it causes the following import error:

File "<stdin>", line 1, in <module>
ImportError: No module named pmw

I have looked at the files that were installed and there is no pmw.py. Does anybody know what needs to be done to...
