How to activate an Anaconda environment
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?
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
Note that the command for activating an environment has changed in Conda version 4.4. The recommended way of activating an environment is now conda activate myenv
instead of source activate myenv
. To enable the new syntax, you should modify your .bashrc
file. The line that currently reads something like
export PATH="<path_to_your_conda_install>/bin:$PATH"
Should be changed to
. <path_to_your_conda_install>/etc/profile.d/conda.sh
This only adds the conda
command to the path, but does not yet activate the base
environment (which was previously called root
). To do also that, add another line
conda activate base
after the first command. See all the details in Anaconda's blog post from December 2017. (I think that this page is currently missing a newline between the two lines, it says .../conda.shconda activate base
).
(This answer is valid for Linux, but it might be relevant for Windows and Mac as well)
