* Avoid `TrainablePipe.finish_update` getting called twice during training
PR #12136 fixed an issue where the tok2vec pipe was updated before
gradient were accumulated. However, it introduced a new bug that cause
`finish_update` to be called twice when using the training loop. This
causes a fairly large slowdown.
The `Language.update` method accepts the `sgd` argument for passing an
optimizer. This argument has three possible values:
- `Optimizer`: use the given optimizer to finish pipe updates.
- `None`: use a default optimizer to finish pipe updates.
- `False`: do not finish pipe updates.
However, the latter option was not documented and not valid with the
existing type of `sgd`. I assumed that this was a remnant of earlier
spaCy versions and removed handling of `False`.
However, with that change, we are passing `None` to `Language.update`.
As a result, we were calling `finish_update` in both `Language.update`
and in the training loop after all subbatches are processed.
This change restores proper handling/use of `False`. Moreover, the role
of `False` is now documented and added to the type to avoid future
accidents.

* `Language.update`: ensure that tok2vec gets updated
The components in a pipeline can be updated independently. However,
tok2vec implementations are an exception to this, since they depend on
listeners for their gradients. The update method of a tok2vec
implementation computes the tok2vec forward and passes this along with a
backprop function to the listeners. This backprop function accumulates
gradients for all the listeners. There are two ways in which the
accumulated gradients can be used to update the tok2vec weights:
1. Call the `finish_update` method of tok2vec *after* the `update`
method is called on all of the pipes that use a tok2vec listener.
2. Pass an optimizer to the `update` method of tok2vec. In this
case, tok2vec will give the last listener a special backprop
function that calls `finish_update` on the tok2vec.
Unfortunately, `Language.update` did neither of these. Instead, it
immediately called `finish_update` on every pipe after `update`. As a
result, the tok2vec weights are updated when no gradients have been
accumulated from listeners yet. And the gradients of the listeners are
only used in the next call to `Language.update` (when `finish_update` is
called on tok2vec again).
This change fixes this issue by passing the optimizer to the `update`
method of trainable pipes, leading to use of the second strategy
outlined above.
The main updating loop in `Language.update` is also simplified by using
the `TrainableComponent` protocol consistently.
* Train loop: `sgd` is `Optional[Optimizer]`, do not pass false
* Language.update: call pipe finish_update after all pipe updates
This does correct and fast updates if multiple components update the
same parameters.
* Add comment why we moved `finish_update` to a separate loop
* Remove backwards-compatible overwrite from Entity Linker
This also adds a docstring about overwrite, since it wasn't present.
* Fix docstring
* Remove backward compat settings in Morphologizer
This also needed a docstring added.
For this component it's less clear what the right overwrite settings
are.

* change logging call for spacy.LookupsDataLoader.v1
* substitutions in language and _util
* various more substitutions
* add string formatting guidelines to contribution guidelines
* Move Entity Linker v1 component to spacy-legacy
This is a follow up to #11889 that moves the component instead of
removing it.
In general, we never import from spacy-legacy in spaCy proper. However,
to use this component, that kind of import will be necessary. I was able
to test this without issues, but is this current import strategy
acceptable? Or should we put the component in a registry?
* Use spacy-legacy pr for CI
This will need to be reverted before merging.
* Add temporary step to log installed spacy-legacy version
* Modify requirements.txt to trigger tests
* Add comment to Python to trigger tests
* TODO REVERT This is a commit with logic changes to trigger tests
* Remove pipe from YAML
Works locally, but possibly this is causing a quoting error or
something.
* Revert "TODO REVERT This is a commit with logic changes to trigger tests"
This reverts commit 689fae71f3.
* Revert "Add comment to Python to trigger tests"
This reverts commit 11840fc598.
* Add more logging
* Try installing directly in workflow
* Try explicitly uninstalling spacy-legacy first
* Cat requirements.txt to confirm contents
In the branch, the thinc version spec is `thinc>=8.1.0,<8.2.0`. But in
the logs, it's clear that a development release of 9.0 is being
installed. It's not clear why that would happen.
* Log requirements at start of build
* TODO REVERT Change thinc spec
Want to see what happens to the installed thinc spec with this change.
* Update thinc requirements
This makes it the same as it was before the merge, >=8.1.0,<8.2.0.
* Use same thinc version as v4 branch
* TODO REVERT Mark dependency check as xfail
spacy-legacy is specified as a git checkout in requirements.txt while
this PR is in progress, which makes the consistency check here fail.
* Remove debugging output / install step
* Revert "Remove debugging output / install step"
This reverts commit 923ea7448b.
* Clean up debugging output
The manual install step with the URL fragment seems to have caused
issues on Windows due to the = in the URL being misinterpreted. On the
other hand, removing it seems to mean the git version of spacy-legacy
isn't actually installed.
This PR removes the URL fragment but keeps the direct command-line
install. Additionally, since it looks like this job is configured to use
the default shell (and not bash), it removes a comment that upsets the
Windows cmd shell.
* Revert "TODO REVERT Mark dependency check as xfail"
This reverts commit d4863ec156.

* Raise spacy legacy version in setup.cfg
* Remove azure build workarounds
* make spacy-legacy version explicit in error message

* Language.distill: copy both reference and predicted
In distillation we also modify the teacher docs (e.g. in tok2vec
components), so we need to copy both the reference and predicted doc.
Problem caught by @shadeMe
* Make new `_copy_examples` args kwonly
* Add the configuration schema for distillation
This also adds the default configuration and some tests. The schema will
be used by the training loop and `distill` subcommand.
* Format
* Change distillation shortopt to -d
* Fix descripion of max_epochs
* Rename distillation flag to -dt
* Rename `pipe_map` to `student_to_teacher`
* Don't re-download installed models
When downloading a model, this checks if the same version of the same
model is already installed. If it is then the download is skipped.
This is necessary because pip uses the final download URL for its
caching feature, but because of the way models are hosted on Github,
their URLs change every few minutes.
* Use importlib instead of meta.json
* Use get_package_version
* Add untested, disabled test
