Conda Environment

Introduction¶

Conda gives you the ability to create environments with packages and their dependencies that will be separate from other environments. This page goes over the basic usage of it.

Create an environment¶

load conda module
```
module load conda
```
or
```
module load anaconda
```
create a new environment
```
conda create -n <evn-name>
```

Note

Conda is a package manager, similar to pip.
Anaconda is a "batteries included" distribution of Python. It uses Conda as its package manager.

list environments¶

lista all your conda environment
```
conda info --envs
```

Tip

The active environment is the one with an asterisk (*)

Install a conda package in the new created environment¶

conda activate env-name
conda install package-name

Notes:

To install a specific version:

conda install package-name=2.3.4

To specify only a major version

conda install package-name=2

specifying channels to use¶

Channels are locations where packages are stored. By default, conda searchs for packages in its default channels. You can specify a channel when installing the package (e.g. conda-forge channel)
```
conda install conda-forge::numpy
```

Mamba¶

Mamba is a package manager that is fully compatible with conda but performs better on certain tasks such as resolving requirements.
