Using Conda

Steps for using conda (initial setup)

Run these commands to create a new conda environment. You don't need to run these every time you use the environment - you can skip to the next section.

Activate conda:

source /shared/software/software-environments/miniconda3/bin/activate

Create a conda environment. You may have to type Y to confirm. This may take a few minutes to setup.
```
conda create --name my_env python=3.12
```
Activate the environemnt
```
conda activate my_env
```
Your shell prompt should now list the environment name:
```
(my_env) [user@ip-10... ~]$
```
Install pip or conda packages. You may have to type Y to confirm. This may take a few minutes to install.
```
conda install -c conda-forge matplotlib
pip install numpy pandas
```
[Optional] If you want to use this conda environment from Jupyter, run the

following commands:

python3 -m pip install ipykernel
python3 -m ipykernel install --user --name py312

Steps for using conda (after initial setup)

Activate conda:

source /shared/software/software-environments/miniconda3/bin/activate

Activate the environment
```
conda activate my_env
```
Your shell prompt should now list the environment name:
```
(my_env) [user@ip-10... ~]$
```
Use srun to execute a shell within the slurm job
```
srun --time=30:00 --pty /bin/bash
```

You can now run your code from the shell, e.g.:

python -c "import numpy as np; print('hello world', np.array([1,2,3]))"

Find location of your conda environment

Sometimes, you will need to know the folder where your conda environment is stored. This will give you a folder where your conda environment is stored on disk.

After activating your environment (see steps above), you can run:

echo $CONDA_PREFIX

The paths path it prints is the path to your conda folder.
