Usage of common installation of prerequisites

• If you do not use direnv yet, add the following to your .bashrc/.zshrc/...

  eval "$(direnv hook $SHELL)"

• Reopen your shell or source the respective rcfile.

• Add a file .envrc with the following content in the root directory of mlhep (you might want to start from a fresh clone):

  PYTHON_VERSION=3.10.14
  ROOT_VERSION=v6-32-04
  ROOUNFOLD_VERSION=2.0.1
  
  PREFIX=/home/pyadmin/software_mlhep
  layout python ${PREFIX}/install/pyenv/versions/${PYTHON_VERSION}/bin/python3
  path_add PYTHONPATH ${PREFIX}/install/root-${ROOT_VERSION}_py-${PYTHON_VERSION}/lib
  PATH_add ${PREFIX}/install/root-${ROOT_VERSION}_py-${PYTHON_VERSION}/bin
  path_add LD_LIBRARY_PATH ${PREFIX}/install/root-${ROOT_VERSION}_py-${PYTHON_VERSION}/lib
  path_add LD_LIBRARY_PATH ${PREFIX}/build/RooUnfold-${ROOUNFOLD_VERSION}_root-${ROOT_VERSION}_py-${PYTHON_VERSION}

• Change to the root directory of mlhep and run:

  direnv allow

• Install required python packages and development version of mlhep using:

  pip install -r requirements.txt
  pip install -e .

• Have fun!
