Create conda environment offline

Question

I have Anaconda installed on a RedHat-6.5 environment that is not connected to the Internet.

Is it possible to create a conda environment based on the existing Anaconda install, or minimal python packages?

FYI: I was able to clone a conda environment that already exists:

conda create -n dummy --clone my_env --offline

Answer 1

Here is a basic bash script I've used to clone without conda attempting to download or compare anything:

orig_env=/path/to/envs/orig
clone_env=/other/path/to/envs/clone

mkdir -p $clone_env
cp -r $orig_env/ $clone_env/

cd $clone_env
grep -rI "$orig_env"
# cd to the folders with references to the old folder name
sed -i -e "s:$orig_env:$clone_env:g" *

source activate $clone_env
conda info

The sed command finds the shebang at the top of files that reference specific locations for copies of python and fixes them.

Hope that helps.

You could try cloning root which is the base env.

conda create -n yourenvname --clone root

With the env created you can install packages like these

conda install packagename --offline
