Install FAST for Python

To install FAST for Python (3.6 or newer), first make sure you have all the necessary requirements installed.

Then you may simply install FAST using pip:

pip install pyfast

Alternatively, you can also download a Python wheel (pyFAST-X.X.X-cp36-abi3-X.whl) from the release page, and install it by:

pip install pyFAST-X.X.X-cp36-abi3-X.whl

To test that your installation works you can do the following:

# Start python
python

Then write the following python code, which will download a test dataset and display an ultrasound image on your screen:

import fast

fast.downloadTestDataIfNotExists() # This will download the test data (~2GB) needed to run the example

importer = fast.ImageFileImporter.New()
importer.setFilename(fast.Config.getTestDataPath() + 'US/Heart/ApicalFourChamber/US-2D_0.mhd')

renderer = fast.ImageRenderer.New()
renderer.setInputConnection(importer.getOutputPort())

window = fast.SimpleWindow.New()
window.set2DMode()
window.addRenderer(renderer)
window.start()

For more examples, see this page.

Troubleshoot

If you get an error saying something like "ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'" or "ImportError: numpy.core.multiarray failed to import". Try to completely remove numpy and reinstall:
Run the following command multiple times, until it says "Cannot uninstall numpy..":

pip uninstall numpy

Then reinstall numpy:

pip install numpy

Uninstall

pip uninstall pyfast

To delete the downloaded test data, and any cached data, simply delete the folders C:/ProgramData/FAST/ on windows, and /home/'your username'/FAST/ on Linux.
