Automatic Conda Environment

Project description

=======================
**Conda-autoenv: Environments by Directory for Conda**
=======================

Automatically activate, update, and deactivate conda environments from an environment.yml file in a directory.

If a pip requirements.txt file exists as well, that will also be installed in the environment and updated upon deactivation.


Install
----

::

$ pip install conda-autoenv
$ echo "source `which conda_autoenv.sh`" >> ~/.bash_profile


Usage
----

Add the following line to your ~/.bashrc or ~/.bash_profile:

::

source ~/conda_autoenv.sh


Case-by-case usage
~~~~~~~~~~~~~~~~~~~~~~~

*Case 1*

If you already have an environment.yml file, place that in your directory (along with your pip requirements.txt file, if applicable), and conda-autoenv will automatically activate that environment.

*Case 2*

If you do not have an environment.yml file, but have a conda environment, export your conda environment to an environment.yml file by executing (in the environment's root directory, while your environment is activated):

::

$ conda env export > environment.yml

[Optional] You may also want your pip packages to automatically be activated and updated with your environment. If so, execute:

::

$ pip freeze > requirements.txt

*Case 3*

If you do not have a conda environment, create one by executing (replace ENV_NAME with the name you would like to call your environment):

::

$ conda create -n ENV_NAME

Then, activate your environment by executing (replace ENV_NAME with the name you gave your environment):

::

$ source activate ENV_NAME

Finally, export your environment to an environment.yml file to be automatically activated later:

::

$ conda env export > environment.yml

[Optional] You may also want your pip packages to automatically be activated and updated with your environment. If so, execute:

::

$ pip freeze > requirements.txt
