The script in this repository is a quick and easy way of installing the latest version of nnpdf into your computer under a conda environment:

curl https://raw.githubusercontent.com/NNPDF/binary-bootstrap/master/bootstrap.sh -o bootstrap.sh
sh bootstrap.sh

and, assuming that the initialization step was accepted in the previous script,

conda create -n nnpdf_env nnpdf -y
conda activate nnpdf_env

This script does three things:

• Download and install conda, trying to get the right architecture for the computer. You can run the following in your terminal:

• Set the appropiriate conda channels to install the NNPDF dependencies. This is done by writting a ~/.condarc file with the following content:

channels:
  - https://packages.nnpdf.science/public
  - conda-forge
  - defaults

In case the file exists, the script doesn't touch it (as not even with conda config is it easy to set the channels in order).

Note: Make sure that the order of the channels is the same as above Otherwise you might receive incompatible packages. Defaults is not necessary.

Common issues

In case of a conflict between local and conda-installed packages, use the environment flag PYTHONUSERBASE:

export PYTHONUSERBASE=intentionally-disabled

If the installation of the nnpdf package hangs or takes a long time, a solution is to use the libmamba solver as explained here. Note that from September '23, or equivalently from conda version 23.9.0, libmamba will be the default solver in conda so after this date updating conda conda update -n base conda should be enough.
