ImportError: No module named 'spacy.en'

Yes, I can confirm that your solution is correct. The version of spaCy you downloaded from pip is v2.0, which includes a lot of new features, but also a few changes to the API. One of them is that all language data has been moved to a submodule spacy.lang to keep thing cleaner and better organised. So instead of using spacy.en, you now import from spacy.lang.en.

- from spacy.en import English
+ from spacy.lang.en import English

However, it's also worth mentioning that what you download when you run spacy download en is not the same as spacy.lang.en. The language data shipped with spaCy includes the static data like tokenization rules, stop words or lemmatization tables. The en package that you can download is a shortcut for the statistical model en_core_web_sm. It includes the language data, as well as binary weight to enable spaCy to make predictions for part-of-speech tags, dependencies and named entities.

Instead of just downloading en, I'd actually recommend using the full model name, which makes it much more obvious what's going on:

python -m spacy download en_core_web_sm
nlp = spacy.load("en_core_web_sm")

When you call spacy.load, spaCy does the following:

  1. Find the installed model named "en_core_web_sm" (a package or shortcut link).
  2. Read its meta.json and check which language it's using (in this case, spacy.lang.en), and how its processing pipeline should look (in this case, tagger, parser and ner).
  3. Initialise the language class and add the pipeline to it.
  4. Load in the binary weights from the model data so pipeline components (like the tagger, parser or entity recognizer) can make predictions.

See this section in the docs for more details.

I used the following command for installing spacy from anaconda distribution.

conda install -c conda-forge spacy

and after that, I was able to download English using the following command without any error.

 python -m spacy download en

I had to use en_core_web_sm instead of en to make that work. It is complaining about permission problem. The following works perfectly:

import spacy
spacy.load('en_core_web_sm')
from spacy.lang.en import English

I think that there is a confusion in the answers provided. Correct things mentioned:

  • you should import from spacy.lang.en
  • spacy.load('en') is indeed a shortcut for loading models.

But: the file en_core_web_sm is not the same file as the one you import from spacy.lang.en. Actually, the first file is produced from the second after training with spacy train in a dataset and then packaging the result. spacy.lang.en contains the model definition: lemmas lookup table, stop_words, lexical attributes (and more). But that and only that. It is not trained with a dataset so that the dependency graph and other functionalities can work.

I think this should be clear enough when working with spaCy.

the en_core_web_sm folder was downloaded outside the spacy folder. I copied it into the spacy/data folder and could run the code as documented in spacy

Anyone facing this issue on Windows 10 and Anaconda installation , look for your conda python executable using where python on command line before running the script.

In my case, the python on the PATH was

C:\Users\XXX\.windows-build-tools\python27\python.exe

whereas what I needed was from

c:\Users\XXX\AppData\Local\Continuum\anaconda3\python.exe

Just add the correct python on the path , or go to this location and run

python -m spacy download en

and it should work.
