## Pretrained pipeline design {#design}
The spaCy v3 pretrained pipelines are designed to be efficient and configurable.
For example, multiple components can share a common "token-to-vector" model and
it's easy to swap out or disable the lemmatizer. The pipelines are designed to
be efficient in terms of speed and size and work well when the pipeline is run
in full.
When modifying a pretrained pipeline, it's important to understand how the
components **depend on** each other. Unlike spaCy v2, where the `tagger`,
`parser` and `ner` components were all independent, some v3 components depend on
earlier components in the pipeline. As a result, disabling or reordering
components can affect the annotation quality or lead to warnings and errors.
Main changes from spaCy v2 models:
- The [`Tok2Vec`](/api/tok2vec) component may be a separate, shared component. A
component like a tagger or parser can
[listen](/api/architectures#Tok2VecListener) to an earlier `tok2vec` or
`transformer` rather than having its own separate tok2vec layer.
- Rule-based exceptions move from individual components to the
`attribute_ruler`. Lemma and POS exceptions move from the tokenizer exceptions
to the attribute ruler and the tag map and morph rules move from the tagger to
the attribute ruler.
- The lemmatizer tables and processing move from the vocab and tagger to a
separate `lemmatizer` component.
### CNN/CPU pipeline design
In the `sm`/`md`/`lg` models:
- The `tagger`, `morphologizer` and `parser` components listen to the `tok2vec`
component.
- The `attribute_ruler` maps `token.tag` to `token.pos` if there is no
`morphologizer`. The `attribute_ruler` additionally makes sure whitespace is
tagged consistently and copies `token.pos` to `token.tag` if there is no
tagger. For English, the attribute ruler can improve its mapping from
`token.tag` to `token.pos` if dependency parses from a `parser` are present,
but the parser is not required.
- The rule-based `lemmatizer` (Dutch, English, French, Greek, Macedonian,
Norwegian and Spanish) requires `token.pos` annotation from either
`tagger`+`attribute_ruler` or `morphologizer`.
- The `ner` component is independent with its own internal tok2vec layer.
<!-- TODO: pretty diagram -->
### Transformer pipeline design
In the tranformer (`trf`) models, the `tagger`, `parser` and `ner` (if present)
all listen to the `transformer` component. The `attribute_ruler` and
`lemmatizer` have the same configuration as in the CNN models.
<!-- TODO: pretty diagram -->
### Modifying the default pipeline
For faster processing, you may only want to run a subset of the components in a
pretrained pipeline. The `disable` and `exclude` arguments to
[`spacy.load`](/api/top-level#spacy.load) let you control which components are
loaded and run. Disabled components are loaded in the background so it's
possible to reenable them in the same pipeline in the future with
[`nlp.enable_pipe`](/api/language/#enable_pipe). To skip loading a component
completely, use `exclude` instead of `disable`.
#### Disable part-of-speech tagging and lemmatization
To disable part-of-speech tagging and lemmatization, disable the `tagger`,
`morphologizer`, `attribute_ruler` and `lemmatizer` components.
```python
# Note: English doesn't include a morphologizer
nlp = spacy.load("en_core_web_sm", disable=["tagger", "attribute_ruler", "lemmatizer"])
nlp = spacy.load("en_core_web_trf", disable=["tagger", "attribute_ruler", "lemmatizer"])
```
<Infobox variant="warning" title="Rule-based lemmatizers require Token.pos">
The lemmatizer depends on `tagger`+`attribute_ruler` or `morphologizer` for
Dutch, English, French, Greek, Macedonian, Norwegian and Spanish. If you disable
any of these components, you'll see lemmatizer warnings unless the lemmatizer is
also disabled.
</Infobox>
#### Use senter rather than parser for fast sentence segmentation
If you need fast sentence segmentation without dependency parses, disable the
`parser` use the `senter` component instead:
```python
nlp = spacy.load("en_core_web_sm")
nlp.disable_pipe("parser")
nlp.enable_pipe("senter")
```
The `senter` component is ~10&times; faster than the parser and more accurate
than the rule-based `sentencizer`.
#### Switch from rule-based to lookup lemmatization
For the Dutch, English, French, Greek, Macedonian, Norwegian and Spanish
pipelines, you can switch from the default rule-based lemmatizer to a lookup
lemmatizer:
```python
# Requirements: pip install spacy-lookups-data
nlp = spacy.load("en_core_web_sm")
nlp.remove_pipe("lemmatizer")
nlp.add_pipe("lemmatizer", config={"mode": "lookup"}).initialize()
```
#### Disable everything except NER
For the non-transformer models, the `ner` component is independent, so you can
disable everything else:
```python
nlp = spacy.load("en_core_web_sm", disable=["tok2vec", "tagger", "parser", "attribute_ruler", "lemmatizer"])
```
In the transformer models, `ner` listens to the `transformer` component, so you
can disable all components related tagging, parsing, and lemmatization.
```python
nlp = spacy.load("en_core_web_trf", disable=["tagger", "parser", "attribute_ruler", "lemmatizer"])
```
#### Move NER to the end of the pipeline
For access to `POS` and `LEMMA` features in an `entity_ruler`, move `ner` to the
end of the pipeline after `attribute_ruler` and `lemmatizer`:
```python
# load without NER
nlp = spacy.load("en_core_web_sm", exclude=["ner"])
# source NER from the same pipeline package as the last component
nlp.add_pipe("ner", source=spacy.load("en_core_web_sm"))
# insert the entity ruler
nlp.add_pipe("entity_ruler", before="ner")
```

### Multiprocessing {#multiprocessing}
spaCy includes built-in support for multiprocessing with
[`nlp.pipe`](/api/language#pipe) using the `n_process` option:
```python
# Multiprocessing with 4 processes
docs = nlp.pipe(texts, n_process=4)
# With as many processes as CPUs (use with caution!)
docs = nlp.pipe(texts, n_process=-1)
```
Depending on your platform, starting many processes with multiprocessing can add
a lot of overhead. In particular, the default start method `spawn` used in
macOS/OS X (as of Python 3.8) and in Windows can be slow for larger models
because the model data is copied in memory for each new process. See the
[Python docs on multiprocessing](https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods)
for further details.
For shorter tasks and in particular with `spawn`, it can be faster to use a
smaller number of processes with a larger batch size. The optimal `batch_size`
setting will depend on the pipeline components, the length of your documents,
the number of processes and how much memory is available.
```python
# Default batch size is `nlp.batch_size` (typically 1000)
docs = nlp.pipe(texts, n_process=2, batch_size=2000)
```
<Infobox title="Multiprocessing on GPU" variant="warning">
Multiprocessing is not generally recommended on GPU because RAM is too limited.
If you want to try it out, be aware that it is only possible using `spawn` due
to limitations in CUDA.
</Infobox>
<Infobox title="Multiprocessing with transformer models" variant="warning">
In Linux, transformer models may hang or deadlock with multiprocessing due to an
[issue in PyTorch](https://github.com/pytorch/pytorch/issues/17199). One
suggested workaround is to use `spawn` instead of `fork` and another is to limit
the number of threads before loading any models using
`torch.set_num_threads(1)`.
