I created virtualenv for few months. And I encountered a problem.
When I activate virtual environment I have access to lib like django :
source virtualenv/jsms/bin/activate
(jsms)local% python
Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 23 2015, 02:52:03)

Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> exit()
(jsms)local% deactivate
But when I use python from the bin folder I can't access to django :
local% virtualenv/jsms/bin/python
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

Type "help", "copyright", "credits" or "license" for more information.
>>> import django
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named django
More strange, when I use python3.4 from the bin folder, I am using python 2.7 :
local% virtualenv/jsms/bin/python3.4
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

Do you know a way to access lib directly from python in the bin folder ?
activate is just a bash script, so you can always take a look at the activate file and see what it is doing, but I think what you’re looking for is the env variable PYTHONHOME. I would try:
export OLD_PYTHON_HOME="$PYTHONHOME"
unset PYTHONHOME
virtualenv/jsms/bin/python3.4 --version
For windows, you would use the following code from the activate.bat template:
if defined PYTHONHOME (
set _OLD_VIRTUAL_PYTHONHOME=%PYTHONHOME%
set PYTHONHOME=
)

I've successfully compiled the caffe library and the python module.
I can do this:

But, bizarrely, this fails:

I cannot understand this at all! Whenever I try to run using iPython notebook I get the same crash.
Any ideas as to what may be causing this, and how I might fix it, or at least get iPython Notebook to use the different python version so I can run this thing?
Thanks!
I try to visualize graph with matplotlib in python but I have few problem in my mac (Yosemite 10.10.2). I already installed matplotlib, and I know that I have 2 version of python installed in my computer, which are 2.7.8 and 2.7.6
Using default interpreter which is python 2.7.8, I got this error
dhcPlus-mbp:~ macbook$ python
Python 2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35)

>>> import matplotlib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named matplotlib
But if I try this one, it works on terminal. But I can't build straight from my Sublime with Ctrl+B
dhcPlus-mbp:~ macbook$ /usr/bin/python

My question is, how could I change default python interpreter so I can use the 2.7.6 in my environment?
Any help is greatly appreciated. Thank you very much.
This problem solved by removing the extra Python libraries on Mavericks by
sudo rm -rf /Library/Frameworks/Python.framework/

The issue was with that a prior Python was installed (2.7.1) previously and MacPorts installed a new one (2.7.6) but did not update the Mac Sym links etc
So I had to futz with my PATH
$ vi ~/.bash_profile
.
.
export PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH
.
.
$ source ~/.bash_profile
$ python --version

so i upgraded to Mavericks hoping that my scripts would be fine . . . luckily when I run my scripts in Coderunner they work . i do simple test scripts in the terminal because its easy and i like the way it looks. i'm not sure why the frameworks work in coderunner but not the terminal.
does anyone have any idea how to fix this ?
i tried updating the software and got the same error
