fastxtend requires fastai to be installed. See http://docs.fast.ai/ for installation instructions.
To install with dependencies for vision, audio, or all tasks run one of:
pip install fastxtend[vision] pip install fastxtend[audio] pip install fastxtend[all]
Like fastai, fastxtend provides safe wildcard imports using python’s
from fastai.vision.all import * from fastxtend.vision.all import *
In general, import fastxtend after all fastai imports, as fastxtend modifies fastai. Any method modified by fastxtend is backwards compatible with the original fastai code.
