Creating Conda Environment

June 09, 2021

Here are the steps:

1. Create environment with specific Python and package versions
2. Activate the environment
3. List packages in environment
4. Install PyTorch
5. Deactivate environment
6. List environments

Create Environment

Enter this command in Terminal to install Python 3.6, NumPy 1.13.3, and the newest version of SciPy.
conda create -n pytorch python=3.6 numpy=1.13.3 scipy

Note: including a conda package without a version number installs the latest and greatest by default.

Activate Environment

You have to activate the environment to actually use it. Do this like so:
source activate pytorch

List Packages

Now we’re inside the pytorch container (notice pytorch in parantheses?). We can see which packages are installed by typing:
conda list

Install PyTorch

Let’s install PyTorch while we’re here.
conda install pytorch torchvision -c pytorch

Deactivate Environment

We can return to the root environment by typing:
source deactivate

List Environments

We can also see which environments are installed.
conda info --envs
