# PyTorch Tutorials documentation build configuration file, created by
# sphinx-quickstart on Wed Mar  8 22:38:10 2017.
#
# This file is execfile()d with the current directory set to its
# containing dir.
#
# Note that not all possible configuration values are present in this
# autogenerated file.
#
# All configuration values have a default; values that are commented out
# serve to show the default.
#

# Because the sphinx gallery might take a long time, you can control specific
# files that generate the results using `GALLERY_PATTERN` environment variable,
# For example to run only `neural_style_transfer_tutorial.py`:
#   GALLERY_PATTERN="neural_style_transfer_tutorial.py" make html
# or
#   GALLERY_PATTERN="neural_style_transfer_tutorial.py" sphinx-build . _build
#
# GALLERY_PATTERN variable respects regular expressions.

# If extensions (or modules to document with autodoc) are in another directory,
# add these directories to sys.path here. If the directory is relative to the
# documentation root, use os.path.abspath to make it absolute, like shown here.
