Create a virtual environment to specify Python and R

Many applications require specific versions of R and Python or a combination of additional modules. As there might be conflicts between those modules, we recommend to use virtual environments to manage and use those packages.  

Individual steps

Log in to ERISOne:

#$ssh erisone

then load the anaconda module:

$module load anaconda/3-5.0.1

then you can create the conda environment:

$conda create --name env_name 

you can already add requirements here like:

$conda create --name env_name python=3.7 R=3.6

execution will take a while. Note that you do not need to specify a version. Do not specify it when you do not use R or Python. 

To activate the enviorment you type:

$conda activate env_name

If you have never used conda, it will give you an error:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.

If your shell is Bash or a Bourne variant, enable conda for the current user with

$ echo ". /apps/software-2.12/Anaconda3/5.2.0/etc/profile.d/" >> ~/.bashrc

Do as the error message suggests:

$ echo ". /apps/software-2.12/Anaconda3/5.2.0/etc/profile.d/" >> ~/.bashrc

 It will add conda to your path so you can activate the environment. for the changes to be active you need to log out and log in again:

  $source ~/.bashrc

After this or a log in you can do:

$conda activate env_name

in this virtual environment you can then install packages with conda install package_name (e.g.) :

$conda install package 

Note that you need to add:


conda activate env_name

To your lsf scripts.
