Prerequisites and Installation

Prerequisites

To run TROVA, you need:

1- Create a python environment with conda, for example:

conda create -n py38 python=3.8 conda activate py38

  1. The main Python packages that must be installed are the following (consider using the proposed options):

  • numpy (use conda install numpy)

  • mpi4py (use pip install mpi4py or conda install mpi4py)

  • time (use conda install -c conda-forge time)

  • netCDF4 (use conda install -c conda-forge netcdf4)

  • scipy (use conda install scipy)

  • importlib (use conda install -c conda-forge importlib)

  • cartopy (use conda install -c conda-forge cartopy)

  • setuptools (use pip install setuptools==58.2.0)

  • hdf5 (use pip install hdf5)

Installation

1- First option

You must check that all the packages are installed and that there is no error message when they are imported.

  • Clone the repository:

git clone https://github.com/tramo-ephyslab/TROVA-master.git

  • Enter the TROVA-master/src/ directory and execute the install_trova.sh code.

sh install_trova.sh

2- Second option:

With this option conda will install the necessary TROVA dependencies.

conda install -c tramo-ephyslab trova

Once installed to check and create the fortran functions the first time it is used, open an ipython and run the following command:

import trova

NOTE: From now on it must have been installed in the python environment and can be used directly like any library.

Possible problems with python packages:

  • If you have a problem with the mpi4py library, please check that all the necessary executables are in the created environment (e.g. “libmpi.so.12”).

If they do not exist, create a symbolic link to the environment you are using (e.g ln -s /home/jose/WRF/Library/lib/libmpi.so.12 /home/jose/anaconda3/envs/test_env/lib)
