Windows - Installation Using Pyenv

1. Pyenv Installation

  • Install pyenv to install necessary Python version (you do not need to do this if you already have a Python versioning software like Anaconda installed):

  • To install pyenv run in the powershell:

Invoke-WebRequest -UseBasicParsing -Uri "https://raw.githubusercontent.com/pyenv-win/pyenv-win/master/pyenv-win/install-pyenv-win.ps1" -OutFile "./install-pyenv-win.ps1"; &"./install-pyenv-win.ps1"

2. Python Installation

  • Restart the powershell

  • Then run in the powershell

pyenv install <python_version>

for example

pyenv install 3.11.3

<python_version> is the Python version you want to install (3.11.3 or higher is suggested for NOMAD-CAMELS).

3. Install CAMELS

  • Create a folder where you want to install CAMELS (e.g. \NOMAD-CAMELS\)

  • Run in your powershell

    cd \NOMAD-CAMELS\;pyenv local <python_version>

  • If you have a working Python environment (python -V in /NOMAD-CAMELS/ returns <python_version>) then you can continue to install CAMELS.

  • Now run the command

    python -m venv .desertenv

    in this folder to create a virtual Python environment (using the Python version given by pyenv local <python_version>)

  • Activate the environment with

    .\.desertenv\Scripts\activate

  • Now type

    pip install nomad-camels

    to install CAMELS.

4. Run 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

python .\CAMELS_start.py
