I am evaluating the Enthought package. I installed the 32bit canopy (downloaded from https://www.enthought.com/downloads/) in Ubuntu.
$ sudo bash canopy-1.0.1-rh5-32.sh
Upon testing I don't see scipy in /usr/local/Canopy/appdata/canopy-1.0.0.1160.rh5-x86/lib/python2.7/site-packages:

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 have installed python 2.7.10 in CentOS 6.5. Then I installed matplotlib using pip. However, I am getting the following error when trying to import matplotlib.pyplot.

tkinter seems to be installed.
"Package tkinter-2.6.6-66.el6_8.x86_64 already installed and latest version"
I have _tkinter.so module in python2.6/lib-dynload, but nothing related to tkinter under python2.7/lib-dynload.
/usr/lib64/python2.6/lib-dynload/_tkinter.so
/usr/local/lib/python2.7/lib-tk/test/test_tkinter
Also, I verified sys.path in python to get the following:
Python 2.7.10 (default, Jun 1 2017, 18:51:46)

/usr/local/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/site-packages
This may be a problem with your python library path. Check to see where tkinter is installed, and make sure that you have that available to your Python interpreter. Can you import anything else from tkinter?
Try to install tkinter as they said ”no module named _tkinter“.
You can do so with that command:
sudo apt-get install python-tk

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
When I try to import PYMC installed with pip, enpgk or the canopy GUI package manager, I tried all of them and without success.

I tried to install GFORTRAN with :
~$ sudo apt-get install gfortran-4.6
but I still get the same error.
(there are other questions very similar indeed, but usually the answer has to do with Anaconda and I'm using Canopy)
Any idea of what is going on ? I can import other packages.
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.
I get a strange error when trying to use Celery from python on OS X 10.9.5. This used to work, but it's now (apparently) failing to use some C library when importing kombu.five.

Found it, thanks TimSmith! It was a conflict in the DYLD_FALLBACK_LIBRARY_PATH environment variable between the libraries used by Homebrew Python and Paraview.
