I am trying to install Anaconda (32-bit) over an existing Python environment (32-bit) on a Windows 7 64-bit system. I am able to get Anaconda python environment running, but the navigator won't respond and conda command fails with an error
ValueError: failed to parse CPython sys.version
I have removed C:\Python27; C:\Python27\Scripts; from PATH variable, but I must be missing something!

I was only updating the system environment variable PATH, and was not touching PythonPath, which was set to C:\Python27. This was the cause for that ValueError. I found my solution in this stackoverflow answer.

I have installed TensorFlow and wanted to check the installation. Here is the interaction with the python console.

Could anyone please tell what I am doing wrong? Thanks.
As Yaroslav noted, this is most likely from running too old a version of Python, or you don't have the funcsigs package installed. For the latter, try pip install funcsigs
I managed to break one of my virtual environments. I think I did it by installing pycrypto with pip and uninstalling it with easy_install.
This is what I get when I run python in the venv.

How can I fix this?
You should not name your file types.py as there is a standard library module with the same name (import types).
As such, Python tries to import it as part of some standard library code but it now actually imports your local types.py file, not the module it expects.
So the problem should be fixed when you rename types.py to something else.
I have installed pygtk-all-in-one-2.24.0.win32-py2.7.msi on windows, and installed gaphor by easy_install. When I try to run gaphor, I receive an import error.

Any suggestions would be appreciated!
Did you actually install pygtk? I suspect easy-install should have pulled it in automatically. Did you see any errors during the install? pygtk also requieres installing gtk+.
Do a simple test - start Python in a console (ipython?), and type:
$ python

>>> import pygtk
>>> import gtk
>>>
There should be no error messages.
You can also search the disk for pygtk.py (with the file manager) and for a directory gtk-2.0 or gtk-3.0.

Please help me: how can install the Python Canopy (including scipy, matplotlib etc.)? Do I have to manually install them? I thought the installer shell script installed all these automatically. Am I missing something?

Scipy is installed into a different virtual environment (~/Enthought/Canopy_64bit/System/). In general, you should be running the Python available at ~/Enthought/Canopy_64bit/User/bin/python as described here. Also look at this article for information on how to make Canopy your default Python
I am working on windows box with 8 processors. I have to run a python script that does mass data processing. When run as such, the script uses only one processor. I learnt that, to harness the power of multiple processors, I can use parallel python (pp) library.
I installed the library on my machine and followed the instructions available at http://www.parallelpython.com/content/view/15/30/#QUICKSMP
However, the code to configure pp fails on my machine:
