How to activate an Anaconda environment

Question

I'm on Windows 8, using Anaconda 1.7.5 64bit.

I created a new Anaconda environment with

conda create -p ./test python=2.7 pip

from C:\Pr\TEMP\venv\.

This worked well (there is a folder with a new python distribution). conda tells me to type

activate C:\PR\TEMP\venv\test

to activate the environment, however this returns:

No environment named "C:\PR\temp\venv\test" exists in C:\PR\Anaconda\envs

How can I activate the environment? What am I doing wrong?

Answer 1

Use cmd instead of Powershell! I spent 2 hours before I switched to cmd and then it worked!

create Environment:

conda create -n your_environment_name 

see list of conda environments:

conda env list 

activate your environment:

conda activate your_environment_name 

That's all folks

Answer 2

If this happens you would need to set the PATH for your environment (so that it gets the right Python from the environment and Scripts\ on Windows).

Imagine you have created an environment called py33 by using:

conda create -n py33 python=3.3 anaconda 

Here the folders are created by default in Anaconda\envs, so you need to set the PATH as:

set PATH=C:\Anaconda\envs\py33\Scripts;C:\Anaconda\envs\py33;%PATH% 

Now it should work in the command window:

activate py33 

The line above is the Windows equivalent to the code that normally appears in the tutorials for Mac and Linux:

$ source activate py33

Does `anaconda` create a separate PYTHONPATH variable for each new environment?
