How to allow org-babel to play with python virtual environment?

Question

I have virtual environment set on my system (actually virtualenvwrapper). I would like to direct org babel to use a specific environment in a single code block or on the whole buffer. How can I do it?

Answer 1

I believe I found the solution.

1. Install virtualenvwrapper

2. Run the setup:

   (require 'virtualenvwrapper)
   (venv-initialize-interactive-shells) ;; if you want interactive shell support
   (venv-initialize-eshell) ;; if you want eshell support
   (setq venv-location "/path/to/your/virtualenvs/")
   

3. Finally, workon the desired virtual environment. Then you can run code block and use the desired interpreter.
