A blank pipeline is typically just a tokenizer. You might want to create a blankpipeline when you only need a tokenizer, when you want to add more componentsfrom scratch, or for testing purposes. Initializing the language object directlyyields the same result as generating it using spacy.blank(). In both cases thedefault configuration for the chosen language is loaded, and no pretrainedcomponents will be available.
spaCy currently provides support for the following languages. You can help byimproving the existing language dataand extending the tokenization patterns.See here for details on how tocontribute to development. Also see thetraining documentation for how to train your own pipelines onyour data.

spaCy also supports pipelines trained on more than one language. This isespecially useful for named entity recognition. The language ID used formulti-language or language-neutral pipelines is xx. The language class, ageneric subclass containing only the base language data, can be found inlang/xx.
To train a pipeline using the neutral multi-language class, you can setlang = "xx" in your training config. You can also\import the MultiLanguage class directly, or callspacy.blank("xx") for lazy-loading.
The initialization settings are typically provided in thetraining config and the data is loaded in beforetraining and serialized with the model. This allows you to load the data from alocal path and save out your pipeline and config, without requiring the samelocal path at runtime. See the usage guide on theconfig lifecycle for more background onthis.
The Chinese pipelines provided by spaCy include a custom pkusegmodel trained only onChinese OntoNotes 5.0, since themodels provided by pkuseg include data restricted to research use. Forresearch use, pkuseg provides models for several different domains ("mixed"(equivalent to "default" from pkuseg packages), "news" "web","medicine", "tourism") and for other uses, pkuseg provides a simpletraining API:
The Japanese language class usesSudachiPy for wordsegmentation and part-of-speech tagging. The default Japanese language class andthe provided Japanese pipelines use SudachiPy split mode A. The tokenizerconfig can be used to configure the split mode to A, B or C.
If you run into errors related to sudachipy, which is currently under activedevelopment, we suggest downgrading to sudachipy==0.4.9, which is the versionused for training the current Japanese pipelines.
Note that as of spaCy v3.0, shortcut links like en that create (potentiallybrittle) symlinks in your spaCy installation are deprecated. To downloadand load an installed pipeline package, use its full name:
Pretrained pipeline distributions are hosted onGithub Releases, and youcan find download links there, as well as on the model page. You can also getURLs directly from the command line by using spacy info with the --urlflag, which may be useful for automation.
In some cases, you might prefer downloading the data manually, for example toplace it into a custom directory. You can download the package via your browserfrom the latest releases,or configure your own download script using the URL of the archive file. Thearchive consists of a package directory that contains another directory with thepipeline data.
Since the spacy download command installs the pipeline asa Python package, we always recommend running it from the command line, justlike you install other Python packages with pip install. However, if you needto, or if you want to integrate the download process into another CLI command,you can also import and call the download function used by the CLI via Python.
Keep in mind that the download command installs a Python package into yourenvironment. In order for it to be found after installation, you will need torestart or reload your Python process so that new packages are recognized.
spaCy can be installed for a CUDA-compatible GPU by specifying spacy[cuda],spacy[cuda102], spacy[cuda112], spacy[cuda113], etc. If you know your CUDAversion, using the more explicit specifier allows CuPy to be installed viawheel, saving some compilation time. The specifiers should installcupy.
Once you have a GPU-enabled installation, the best way to activate it is to callspacy.prefer_gpu orspacy.require_gpu() somewhere in yourscript before any pipelines have been loaded. require_gpu will raise an errorif no GPU is available.
If you install spaCy from source or with pip for platforms where there are notbinary wheels on PyPI, you may need to use build constraints if any package inyour environment requires an older version of numpy.
To fix this, create a new virtual environment and install spacy and all of itsdependencies using build constraints.Build constraintsspecify an older version of numpy that is only used while compiling spacy,and then your runtime environment can use any newer version of numpy and stillbe compatible. In addition, use --no-cache-dir to ignore any previously cachedwheels so that all relevant packages are recompiled from scratch:
Install in editable mode. Changes to .py files will be reflected as soon asthe files are saved, but edits to Cython files (.pxd, .pyx) will requirethe pip install command below to be run again. Before installing in editablemode, be sure you have removed any previous installs withpip uninstall spacy, which you may need to run multiple times to remove alltraces of earlier installs.
The spaCy repository includes a Makefile thatbuilds an executable zip file using pex(Python Executable). The executable includes spaCy and all its packagedependencies and only requires the system Python at runtime. Building anexecutable .pex file is often the most convenient way to deploy spaCy, as itlets you separate the build from the deployment process.
This section collects some of the most common errors you may come across wheninstalling, loading and using spaCy, as well as their solutions. Also see theDiscussions FAQ Thread,which is updated more frequently and covers more transitory issues.
what is difference between spacy.load('en_core_web_sm') and spacy.load('en')? This link explains different model sizes. But i am still not clear how spacy.load('en_core_web_sm') and spacy.load('en') differ
When you spacy download en, spaCy tries to find the best small model that matches your spaCy distribution. The small model that I am talking about defaults to en_core_web_sm which can be found in different variations which correspond to the different spaCy versions (for example spacy, spacy-nightly have en_core_web_sm of different sizes).
When spaCy finds the best model for you, it downloads it and then links the name en to the package it downloaded, e.g. en_core_web_sm. That basically means that whenever you refer to en you will be referring to en_core_web_sm. In other words, en after linking is not a "real" package, is just a name for en_core_web_sm.
However, it doesn't work the other way. You can't refer directly to en_core_web_sm because your system doesn't know you have it installed. When you did spacy download en you basically did a pip install. So pip knows that you have a package named en installed for your python distribution, but knows nothing about the package en_core_web_sm. This package is just replacing package en when you import it, which means that package en is just a softlink to en_core_web_sm.
Of course, you can directly download en_core_web_sm, using the command: python -m spacy download en_core_web_sm, or you can even link the name en to other models as well. For example, you could do python -m spacy download en_core_web_lg and then python -m spacy link en_core_web_lg en. That would make en a name for en_core_web_lg, which is a large spaCy model for the English language.
If you're using a conda virtual environment, be sure that its the same version of Python as that in your base environment. To verify this, run python --version in each environment. If not the same, create a new virtual environment with that version of Python (Ex. conda create --name myenv python=x.x.x).
I'm running PyCharm on MacOS and while none of the above answers completely worked for me, they did provide enough clues and I was finally able to everything working. I am connecting to an ec2 instance and have configured PyCharm such that I can edit on my Mac and it automatically updates the files on my ec2 instance. Thus, the problem was on the ec2 side where it was not finding Spacy even though I installed it several different times and ways. If I ran my python script from the command line, everything worked fine. However, from within PyCharm, it was initially not finding Spacy and the models. I eventually fixed the "finding" spacy issue using the above recommendation of adding a "requirements.txt" file. But the models were still not recognized.
I then load a model using the explicit path and it worked from within PyCharm (note the path used goes all the way to en_core_web_lg-3.0.0; you will get an error if you do not use the folder with the config.cfg file):
[Errno 2] No such file or directory: '....\en_core_web_sm\en_core_web_sm-2.3.1\vocab\lexemes.bin'orOSError: [E050] Can't find model 'en_core_web_sm'.... It doesn't seem to be a shortcut link, a Python package or a valid path to a data directory.
When you run python -m spacy download en_core_web_sm, it will prettymuch execute the same thing (pip install [link]), with pip running ina subprocess. The download also takes care of finding you the rightversion of the model and outputting helpful messages.
I am deploying an app using streamlit share and getting this error. The code is working fine on my local but getting error on deployment. The requirement file is update and has an entry as
