### Python conventions
All Python code must be written in an **intersection of Python 2 and Python 3**. This is easy in Cython, but somewhat ugly in Python. We could use some extra utilities for this. Please pay particular attention to code that serialises json objects.
All Python code must be written in an **intersection of Python 2 and Python 3**. This is easy in Cython, but somewhat ugly in Python. Logic that deals with Python or platform compatibility should only live in [`spacy.compat`](spacy/compat.py). To distinguish them from the builtin functions, replacement functions are suffixed with an undersocre, for example `unicode_`. If you need to access the user's version or platform information, for example to show more specific error messages, you can use the `is_config()` helper function.
```python
from .compat import unicode_, json_dumps, is_config
compatible_unicode = unicode_('hello world')
compatible_json = json_dumps({'key': 'value'})
if is_config(windows=True, python2=True):
print("You are using Python 2 on Windows.")
```
Code that interacts with the file-system should accept objects that follow the `pathlib.Path` API, without assuming that the object inherits from `pathlib.Path`. If the function is user-facing and takes a path as an argument, it should check whether the path is provided as a string. Strings should be converted to `pathlib.Path` objects.
@ -95,6 +104,8 @@ At the time of writing (v1.7), spaCy's serialization and deserialization functio
Although spaCy uses a lot of classes, inheritance is viewed with some suspicion — it's seen as a mechanism of last resort. You should discuss plans to extend the class hierarchy before implementing.
We have a number of conventions around variable naming that are still being documented, and aren't 100% strict. A general policy is that instances of the class `Doc` should by default be called `doc`, `Token` `token`, `Lexeme` `lex`, `Vocab` `vocab` and `Language` `nlp`. You should avoid naming variables that are of other types these names. For instance, don't name a text string `doc` — you should usually call this `text`. Two general code style preferences further help with naming. First, lean away from introducing temporary variables, as these clutter your namespace. This is one reason why comprehension expressions are often preferred. Second, keep your functions shortish, so that can work in a smaller scope. Of course, this is a question of trade-offs.
### Cython conventions
spaCy's core data structures are implemented as [Cython](http://cython.org/) `cdef` classes. Memory is managed through the `cymem.cymem.Pool` class, which allows you to allocate memory which will be freed when the `Pool` object is garbage collected. This means you usually don't have to worry about freeing memory. You just have to decide which Python object owns the memory, and make it own the `Pool`. When that object goes out of scope, the memory will be freed. You do have to take care that no pointers outlive the object that owns them — but this is generally quite easy.

If this is confusing, consider that the compiler couldn't deal with `for item in int_array:` — there's no length attached to a raw pointer, so how could we figure out where to stop? The length is provided in the slice notation as a solution to this. Note that we don't have to declare the type of `item` in the code above -- the compiler can easily infer it. This gives us tidy code that looks quite like Python, but is exactly as fast as C — because we've made sure the compilation to C is trivial.

Your functions cannot be declared `nogil` if they need to create Python objects or call Python functions. This is perfectly okay — you shouldn't torture your code just to get `nogil` functions. However, if your function isn't `nogil`, you should compile your module with `cython -a --cplus my_module.pyx` and open the resulting `my_module.html` file in a browser. This will let you see how Cython is compiling your code. Calls into the Python run-time will be in bright yellow. This lets you easily see whether Cython is able to correctly type your code, or whether there are unexpected problems.

Example of training an additional entity type
This script shows how to add a new entity type to an existing pre-trained NER
model. To keep the example short and simple, only four sentences are provided
as examples. In practice, you'll need many more — a few hundred would be a
good start. You will also likely need to mix in examples of other entity
types, which might be obtained by running the entity recognizer over unlabelled
sentences, and adding their annotations to the training set.
The actual training is performed by looping over the examples, and calling
`nlp.entity.update()`. The `update()` method steps through the words of the
input. At each word, it makes a prediction. It then consults the annotations
provided on the GoldParse instance, to see whether it was right. If it was
wrong, it adjusts its weights so that the correct action will score higher
next time.
After training your model, you can save it to a directory. We recommend
wrapping models as Python packages, for ease of deployment.

| All #[+a("/docs/usage/models") spaCy models] support online learning, so
| you can update a pre-trained model with new examples. You can even add
| new classes to an existing model, to recognise a new entity type,
| part-of-speech, or syntactic relation. Updating an existing model is
| particularly useful as a "quick and dirty solution", if you have only a
| few corrections or annotations.
+h(2, "improving-accuracy") Improving accuracy on existing entity types
p
| To update the model, you first need to create an instance of
| #[+api("goldparse") #[code spacy.gold.GoldParse]], with the entity labels
| you want to learn. You will then pass this instance to the
| #[+api("entityrecognizer#update") #[code EntityRecognizer.update()]]
| method. For example:
+code.
import spacy
from spacy.gold import GoldParse
nlp = spacy.load('en')
doc = nlp.make_doc(u'Facebook released React in 2014')
gold = GoldParse(doc, entities=['U-ORG', 'O', 'U-TECHNOLOGY', 'O', 'U-DATE'])
nlp.entity.update(doc, gold)
p
| You'll usually need to provide many examples to meaningfully improve the
| system — a few hundred is a good start, although more is better. You
| should avoid iterating over the same few examples multiple times, or the
| model is likely to "forget" how to annotate other examples. If you
| iterate over the same few examples, you're effectively changing the loss
| function. The optimizer will find a way to minimize the loss on your
| examples, without regard for the consequences on the examples it's no
| longer paying attention to.
p
| One way to avoid this "catastrophic forgetting" problem is to "remind"
| the model of other examples by augmenting your annotations with sentences
| annotated with entities automatically recognised by the original model.
| Ultimately, this is an empirical process: you'll need to
| #[strong experiment on your own data] to find a solution that works best
| for you.
+h(2, "adding") Adding a new entity type
p
| You can add new entity types to an existing model. Let's say we want to
| recognise the category #[code TECHNOLOGY]. The new category will include
| programming languages, frameworks and platforms. First, we need to
| register the new entity type:
+code.
nlp.entity.add_label('TECHNOLOGY')
p
| Next, iterate over your examples, calling #[code entity.update()]. As
| above, we want to avoid iterating over only a small number of sentences.
| A useful compromise is to run the model over a number of plain-text
| sentences, and pass the entities to #[code GoldParse], as "true"
| annotations. This encourages the optimizer to find a solution that
| predicts the new category with minimal difference from the previous
| output.
+h(2, "saving-loading") Saving and loading
p
| After training our model, you'll usually want to save its state, and load
| it back later. You can do this with the #[code Language.save_to_directory()]
| method:
+code.
nlp.save_to_directory('/home/me/data/en_technology')
p
| To make the model more convenient to deploy, we recommend wrapping it as
| a Python package, so that you can install it via pip and load it as a
| module. spaCy comes with a handy #[+a("/docs/usage/cli#package") CLI command]
| to create all required files and directories.
+code(false, "bash").
python -m spacy package /home/me/data/en_technology /home/me/my_models

| provided as examples. In practice, you'll need many more —
| #[strong a few hundred] would be a good start. You will also likely need
