### Creating Custom Anaconda Environments
{{% notice info %}}
**NOTE:**
By default, conda packages are installed in the user's
`home`
directory.
Since Crane's
`home`
directories are not writeable from the worker nodes,
the commands for installing, adding and removing conda packages shown here
should be performed on the
**login node**
, and not as part of an interactive or SLURM job.

The
`create`
command is used to create a new environment. It requires
at a minimum a name for the environment, and at least one package to
install. For example, suppose we wish to create a new environment, and

Our new environment is now active, and we can use it. The shell prompt will change to indicate this as well.
### Using /common for environments
By default, conda environments are installed in the user's
`home`
directory at
`~/.conda/envs`
.
This is fine for smaller environments, but larger environments (especially ML/AI-based ones) can quickly
exhaust the space in the
`home`
directory.
For larger environments, we recommend using the
`$COMMON`
folder instead. To do so, use the
`-p`
option
instead of
`-n`
for
`conda create`
. For example, creating the same environment as above but
placing it in the folder
`$COMMON/mynumpy`
instead.
{{% panel theme="info" header="Create environment in /common" %}}
{{
<
highlight
bash
>
}}
conda create -p $COMMON/mynumpy numpy=1.17
{{
<
/
highlight
>
}}
{{% /panel %}}
To activate the environment, you must use the full path.
{{% panel theme="info" header="Activate environment in /common" %}}
{{
<
highlight
bash
>
}}
conda activate $COMMON/mynumpy
{{
