Installation
Femora is released to PyPI and can also be installed directly from source for development workflows.
Requirements
Before installing Femora, make sure you have:
- Python 3.9 or newer
pip- a normal scientific Python environment with permission to install packages
Femora depends on packages such as vtk, pyvista, scipy, h5py, meshlib, and trame, so a clean virtual environment is strongly recommended.
Recommended: Install From PyPI
For most users, the standard installation path is:
This installs the core package and its required dependencies from PyPI.
Optional Extras
Femora exposes a few optional dependency groups depending on your workflow.
Jupyter Support
If you plan to use Femora heavily in notebooks:
METIS / Partitioning Support
If you need partition-related workflows that depend on pymetis:
Extended Local Tooling
If you want the broader optional set used for richer local development environments:
Use this only when you actually want the larger optional stack.
Install From Source
If you are developing Femora itself, testing local changes, or working from the repository:
For source development with optional extras:
An editable install is the right choice when:
- you are modifying Femora source code
- you are working on docs and examples together
- you want local changes reflected immediately without reinstalling
Conda Workflow
If you prefer Conda, create an isolated environment first and then install Femora inside it.
Example:
If you are working from the repository and want to start from the included environment file:
If you rename the environment in environment.yml, activate that name instead of myenv.
Verify the Installation
The quickest verification is to import Femora in Python:
You can also check that the main workflow entry is available:
Local Documentation Workflow
If you are working on the website or docs locally, Femora's repo includes a local workflow helper.
For fast website editing:
For the full combined site check:
The full mode builds:
- the website
- the generated API docs
- the merged local documentation site
Common Notes
Use a Virtual Environment
Do not install Femora into a crowded global Python environment if you can avoid it.
vtk, pyvista, and related packages are easier to manage inside a dedicated environment.
PyPI vs Source
Use PyPI when you want a clean released version.
Use source installation when you want:
- the latest local code
- editable development
- docs or website work
- contribution workflows
Interactive Plotting
Femora supports in-code inspection and plotting workflows. If your local environment is missing visualization-related dependencies, install the optional extras you need or use the richer source-development environment.
Next Steps
After installation:
- read the Getting Started guide
- open the Examples & Tutorials page
- use the API Reference when you need exact manager, class, or method behavior
