Pybrain not working with Python 3.6.1

I installed Python 3.6.1. And then installed pybrain using git (See Screen Shot). Then when I useimport pybrainit works but afterwards when I usefrom pybrain.tools.shortcuts import buildNetworkit gives me error that: Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32

Why is it doing like this? Kindly help me out here. Thanks
EDIT: Excluded screen shots. Added everything in post as per request.

except ImportError, e is Python 2 syntax and you've tried to run the code with Python 3. Install the latest version — the code seems to be fixed in git (it's except ImportError as e now, so it's suitable for both Python 2.7 and Python 3).

Just an update: I was able to resolve the issue by un-installing python, then installing python 3.6.2 (64 bit), using pip3 (pip3 install pybrain) I was able to install the latest version of pybrain which worked flawlessly. Thanks to everyone who tried to help me out when I was fairly new to python. Love this community!!

How do I make pandas installed via Anaconda usable by PyCharm?

I'm on Windows 10 and have installed Anaconda3 (2016-1). When I use Spyder that Anaconda installed, import pandas works.
From PyCharm I however can't import pandas. PyCharm is set to use C:\Users\Chris>C:\Users\Chris\Anaconda3\envs\Conda\python.exe.
If I call the exe directly I also can't import pandas despite it being in the Anaconda3 dictionary.

What do I have to do, that I can import pandas?

It works when I set the path to C:\Users\Chris>C:\Users\Chris\Anaconda3\python.exe instead of using a virtual enviroment with C:\Users\Chris>C:\Users\Chris\Anaconda3\envs\Conda\python.exe as PyCharm suggests.

matplotlib: no module named compat

I have installed python-2.7.5-5ubuntu3 and matplotlib-1.3.1-1ubuntu5 from the ubuntu 14.04 repository via apt-get. Trying to import the library in python 2.7 raises the following import error:
harold#ubuntu:~$ python

ImportError: No module named compat

I checked the directory /usr/share/pyshared/matplotlib and, indeed, cannot find any package called compat.
Any idea what is broken on my system?
Thanks!

I have found same problem on Ubuntu 16 & 14.
Possible source of the problem is damaged instance of matplotlib. Damaged instance overlaps working instance of matplotlib.
Please try to remove broken instance of matplotlib to solve the issue.
Firstly I have looked matplotlib instances:
find / |grep matplotlib | grep __init__\.py$ |more
Secondly I have deleted this folder:
find /usr/share/pyshared/matplotlib -delete

ValueError with 'ciphers' when importing paramiko

I want to install paramiko on win 7 32bit ,the python is 3.3 .
I can compile it，but get follow errors:

Paramiko does not run on Python 3. Yet. I'm working on a development branch (https://github.com/dorianpula/paramiko/tree/python3-support) to add support for Python 3, and I'm working on fixing this particular issue.

"import numpy" results in error in one eclipse workspace, but not in another

Whenever I try importing numpy in my new installation of Eclipse and Pydev, I get the following error:

In [2]: import numpy
To make stuff even more complicated, in another Eclipse workspace, this import works fine. Restarting eclipse didn't help. I also tried to re-config the interpreter in Preferences->python->interpreter->python (as in this question), but the problem still exists
Two additional similar problems were described on SO (this and this), but both of them were observed with IronPython and I couldn't find anything I could use in the few answers that were provided.
EDIT As suggested by dutt, I checked Preferences->Pydev->Interpreter python->libraries in both the tested workspaces (the working one and the one that doesn't). The malfunctioning workspace contained the following library in system libs C:\Python26\lib\site-packages\numpy-1.5.0-py2.6-win32.egg . On the other hand, the working workspace doesn't list any numpy library in its system libraries list. I have removed the above library from the list in the not working workspace.

(Assuming you'r using PyDev) Look in Preferences->Pydev->Interpreter-Python->Libaries, you may have to add NumPy there. Should be located in your python/lib/site-packages folder.

check the version of your python release and numpy release. they should be the same.
It happened to me and I solved it re-installing my python and numpy for win32, although I have a 64-bit machine.
