pywt versus PyWT

To be specific, I am talking about the difference between pywt (PyWavelets) and PyWT (Python Web Toolkit).

I thought I had installed the wavelets package, as I had used pywt freely for several years; however, when I executed,

$ pip install pywt

I got the web toolkit package instead, even though it goes by PyWF now. Executing the inverese:

$ pip uninstall pywt

I got the reassuring,

$ pip uninstall pywtUninstalling PyWT:Proceed (y/n)? y  Successfully uninstalled PyWT

But when I went to use the wavelet package, it was still accessing the ununinstalled web toolkit, which does absolutely nothing for wavelets. So... I imported pywt at the terminal again and looked at the path:

>>> pywt.__path__
['/usr/local/lib/python2.6/dist-packages/pywt']

And then I went in like gangbangers and shot up that joint with,

$ sudo rm -r /usr/local/lib/python2.6/dist-packages/pywt/

Then everything worked out okay.

    >>> import pywt
    >>> from pywt import dwt
    >>> dwt([1,2,3,4,5,6,7,8],'db4')
    (array([  7.06453146,  4.23073611,  1.41360717,  2.83605428,
              5.6633906 ,  8.49718595, 11.3143149  ]),
     array([  2.37131306e-02,  4.09620864e-02,  -6.46752170e-02,

              6.46752170e-02]))
