In OGS we make use of Python packages at different stages, e.g.:
Python packages are usually installed via pip
inside an isolated environment (a virtual environment).
When configuring OGS with OGS_USE_PIP=ON
Python creates a new virtual environment in the .venv
-directory inside your build directory. It will also install required Python packages into this environment. You can see the current environment definition in the file requirements.txt
inside your build-directory.
To manually add Python packages run the following inside your build-directory:
.venv/bin/pip install python-package-name
To activate the environment run source .venv/bin/activate
inside your build directory.
You can use the argument PYTHON_PACKAGES
on AddTest()
to specify additional Python package dependencies.
The following example would install the latest version of numpy
and pandas
version 0.1.2:
AddTest(
...
PYTHON_PACKAGES numpy pandas==0.1.2
...
)
