Installation

From sources

Use git clone command in order to download the source files:

git clone https://github.com/Luispain/TreeLab

From a working Python environment, you can compile using pypi. For example, a user-only installation would be done as follows:

python3 -m pip --user install .

• You may use --user option on order to install only for current user.
• You can use --prefix option to specify the directory where the installation will be done
• You can use -e option to install in developer mode; such that any change in *.py source files will be immediately take effect

If you do not have admin rights and you encounter problems using --prefix, then try force reinstalling all dependencies:

python3 -m pip install --force-reinstall --no-cache-dir --ignore-installed --prefix=/your/path/to/treelab/installation mola-treelab

From stable releases

python3 -m pip --user install mola-treelab

Make sure that the installation bin directory is seen by your PATH environment variable. For exemple, in Linux:

export PATH=$PATH:~/.local/bin
