Installation¶

PyVista is supported on Python versions 3.6+. Previous versions of Python are no longer supported as outlined in this issue.

For the best experience, please considering using Anaconda as a virtual environment and package manager for Python and following the instructions to install PyVista with Anaconda.

Dependencies¶

PyVista is built on top of the Visualization Toolkit (VTK) and NumPy - as such, the following projects are required dependencies of PyVista:

vtk - PyVista directly inherits types from the VTK library.
numpy - NumPy arrays provide a core foundation for PyVista’s data array access.
imageio - This library is used for saving screenshots.
appdirs - Data management for our example datasets so users can download tutorials on the fly.
meshio - Input/Output for many mesh formats.
scooby - Debugging tools

PyPI¶

PyVista can be installed from PyPI using pip:

pip install pyvista

Anaconda¶

To install this package with conda run:

conda install -c conda-forge pyvista

Optional Dependencies¶

The following are a list of optional dependencies and their purpose:

Package	Purpose
`matplotlib`	Using Colormaps
`itkwidgets`	Interactive notebook rendering
`ipyvtklink`	Interactive notebook rendering
`sphinx_gallery`	Capturing PyVista output for docs
`colorcet`	Perceptually uniform colormaps
`cmocean`	Oceanographic colormaps
`imageio-ffmpeg`	Saving movie files
`tqdm`	Status bars for monitoring filters
`trimesh` `rtree` `pyembree`	Vectorised ray tracing

Source / Developers¶

Alternatively, you can install the latest version from GitHub by visiting PyVista, and downloading the source (cloning) by running:

git clone https://github.com/pyvista/pyvista.git
cd pyvista
python -m pip install -e .

The latest documentation for the master branch of PyVista can be found at dev.pyvista.org.

Test Installation¶

You can test your installation by running an example:

from pyvista import examples
examples.plot_wave()

See other examples and demos:

from pyvista import examples
from pyvista import demos

# list all examples
print(dir(examples))

# list all demos
print(dir(demos))

Note

A more comprehensive testing suite is available after cloning the source repository. For details on how to clone and test the PyVista source, please see our Contributing Guide and specifically, the Testing section.

Running on CI Services¶

Please head over to pyvista/gl-ci-hepers for details on setting up CI services like Travis and Azure Pipelines to run PyVista.

Running on MyBinder¶

This section is for advanced users that would like to install and use PyVista with headless displays on notebook hosting services like MyBinder.

Please see this project for a convenient Cookiecutter to get started using PyVista on the notebook hosting service MyBinder.

To get started, the Docker container will need to have libgl1-mesa-dev and xvfb installed through apt-get. For MyBinder, include the following in a file called apt.txt:

libgl1-mesa-dev
xvfb

Then, you need to configure the headless display, for MyBinder, create a file called start and include the following set up script that will run every time your Docker container is launched:

#!/bin/bash
set -x
export DISPLAY=:99.0
export PYVISTA_OFF_SCREEN=true
export PYVISTA_USE_IPYVTK=true
which Xvfb
Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
sleep 3
set +x
exec "$@"

And that’s it! Include PyVista in your Python requirements and get to visualizing your data! If you need more help than this on setting up PyVista for these types of services, hop on Slack and chat with the developers or take a look at this repository that is currently using PyVista on MyBinder.

Running on Remote Servers¶

Using PyVista on remote servers requires similar setup steps as in the above Docker case. As an example, here are the complete steps to use PyVista on AWS EC2 Ubuntu 18.04 LTS (ami-0a313d6098716f372 in us-east-1). Other servers would work similarly.

After logging into the remote server, install Miniconda and related packages:

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh
bash miniconda.sh -b -p miniconda
echo '. $HOME/miniconda/etc/profile.d/conda.sh' >> ~/.bashrc && source ~/.bashrc
conda create --name vtk_env python=3.7
conda activate vtk_env
conda install nodejs  # required when importing pyvista in Jupyter
pip install jupyter pyvista ipyvtklink

# To avoid "ModuleNotFoundError: No module named 'vtkOpenGLKitPython' " when importing vtk
# https://stackoverflow.com/q/32389599
# https://askubuntu.com/q/629692
sudo apt update && sudo apt install python-qt4 libgl1-mesa-glx

Then, configure the headless display:

sudo apt-get install xvfb
export DISPLAY=:99.0
export PYVISTA_OFF_SCREEN=true
export PYVISTA_USE_IPYVTK=true
Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
sleep 3

Reconnect to the server with port-forwarding, and start Jupyter:

ssh -i "your-ssh-key" your-user-name@your-server-ip -L 8888:localhost:8888
conda activate vtk_env
jupyter notebook --NotebookApp.token='' --no-browser --port=8888

Visit localhost:8888 in the web browser.

Running with Sphinx-Gallery¶

In your conf.py, add the following:

import pyvista
# necessary when building the sphinx gallery
pyvista.BUILDING_GALLERY = True
pyvista.OFF_SCREEN = True

# Optional - set parameters like theme or window size
pyvista.set_plot_theme('document')
pyvista.global_theme.window_size = np.array([1024, 768]) * 2

...

# Add the PyVista image scraper to SG
sphinx_gallery_conf = {
    ...
    "image_scrapers": ('pyvista', ..., ),
    ...
}
