Here's the command I used to invoke autopep8 (in parallel!):
git ls-files | grep '\.py$' | xargs -n1 -P`nproc` autopep8 -i
Several rules are ignored in setup.cfg. The goal is to let autopep8
handle everything which it can handle safely, and to disable any rules
which are tricky or controversial to address. We may want to come back
and re-enable some of these rules later, but I'm trying to make this
patch as safe as possible.
Also configures flake8 to match pep8's behavior.
Also configures TravisCI to check the whole project for lint.
The register hook calls now return an object that can be used to remove
the hook. For example,
>>> h = module.register_forward_hook(callback)
>>> h.remove() # removes hook
Or as a context manager:
>>> with module.register_forward_hook(callback):
... pass
This makes it easier for libraries to use hooks without worrying about
name collisions.
Prior to this change, there was a circular reference between Leaf and
Variable. This means that the objects (and referenced Tensors) are not
collected as soon as they go out of scope, which lead to higher memory
usage and out-of-memory errors.
* _forward is renamed forward since users should override it
* some __call__ overrides are changed to forward
* function which return a single variable are changed to return that
variable instead of a one-element tuple
