macOS - Installation

Warning

NOMAD CAMELS might not work on Apple Silicon devices like the M1, M2, etc.

1. Python Installation

There are two ways to install Python on your mac:

Note

Use Pyenv if you want to be abl to easily manage different Python versions (for example 3.9 and 3.11) on your system at the same time.

See here for information on how to install homebrew.

After you installed homebrew and simply want a single Python version to run on your system run this command in the terminal:

brew install python

Use homebrew to install pyenv.

Then install dependencies

brew install openssl readline sqlite3 xz zlib

You can simply run

pip3 install nomad-camels

Type in your terminal

cd NOMAD-CAMELS
pyenv local <python_version>

If you have a working Python environment (python3 -V in /NOMAD-CAMELS/ returns <python_version>) then you can continue to install CAMELS.
Now run the command
```
python3 -m venv .desertenv
```
in this folder to create a virtual Python environment (using the Python version given by pyenv local <python_version>)
Now activate the environment with
```
source .desertenv/bin/activate
```
Now type
```
pip install nomad-camels 
```
to install CAMELS.

You can then run

nomad-camels

or

python -m nomad_camels

to start CAMELS.

If this does not work for you you can go to /.desertenv/Lib/site-packages/nomad_camels/ and run CAMELS using

python3 .\CAMELS_start.py

or run:

python3 ./desertenv/lib/python<version>/site-packages/nomad_camels/CAMELS_start.py
