.. blogpost:: :title: Issues with Sphinx 1.6.1 :keywords: documentation, startup :date: 2017-05-17 :categories: documentation `Sphinx `_ has released a new version 1.6.1 but it breaks a couple of packages. `sphinx_gallery `_ breaks with the following error: :: File "python\lib\site-packages\sphinx_gallery\gen_gallery.py", line 297, in setup if 'sphinx.ext.autodoc' in app._extensions: AttributeError: 'Sphinx' object has no attribute '_extensions' This is probably going to be fixed anytime soon. In the meantime, you can just avoid updating Sphinx or modify the code of this package by removing the test. `sphinxcontrib.images `_ also breaks. I recommand to postpone the update: :: pip install sphinx==1.5.6 *pyquickhelper* should work with both when the images packages will be updated.
