ImportError: No module named fixedpickle when running PyDsTool on Windows 7

问题

I have downloaded PyDsTool for Windows. And I believe I have pointed python in the correct location. But I get the following error

from PyDSTool import *
Traceback (most recent call last):

    import fixedpickle as pickle

ImportError: No module named fixedpickle

回答1:

I solve this problem through uninstalling and reinstalling anaconda. Otherwise the installation of PyDsTools is very simple. It is not really installation at all, just unpack the zip folder and make sure it is in your python path (also add its parent directories to the python path). This may be done through Spyder IDE. Click tools> pythonpath

I received some assistance from the Sourceforge support thread for the PyDStool project here
