Nemo is written in Python (3.6+), and requires the following additional modules to be installed (currently used versions are given in brackets, later versions also probably work):
- numpy (1.19)
- scipy (1.3.0)
- matplotlib (2.1.1)
- astLib (0.11.7)
- pixell (0.17 or later)
- Pillow (5.1.0)
- astropy (4.0)
- PyYAML (3.12)
- CCL (3.0.0+)
- mpi4py (3.0.0)
- colorcet (1.0.0; https://github.com/bokeh/colorcet/releases)
The latest tagged version of Nemo can be installed using pip:
pip install nemo-sz
Dependencies will be installed by pip, except for pyccl and mpi4py.
You may also install using the standard setup.py script, e.g., as root:
sudo python setup.py install
Alternatively,
python setup.py install --user
will install nemo under $HOME/.local (on Ubuntu), and in some other default location on Mac.
You can also use the --prefix option, e.g.,
python setup.py install --prefix=$HOME/local
and then add $HOME/local/bin to $PATH, and e.g., $HOME/local/lib/python3.6/site-packages to
$PYTHONPATH (adjust the path according to your Python version number).
export PATH=$HOME/local/bin:$PATH export PYTHONPATH=$HOME/local/lib/python3.6/site-packages:$PYTHONPATH
If Nemo has installed correctly, then you should find its command line tools are available, for example,
nemo -h
should display a helpful message about the command-line options for the main nemo command.
