ChatterBot error- OSError: [E941] Can't find model 'en'

Question

I tried running my first Chatterbot program (its from the PyPi page of Chatterbot), and when I run it, I get an error. The error is related to Spacy, but I am unable to find a solution.

Here is the code:

from chatterbot.trainers import ChatterBotCorpusTrainer

chatbot = ChatBot('Ron Obvious')

trainer = ChatterBotCorpusTrainer(chatbot)

trainer.train("chatterbot.corpus.english")

chatbot.get_response("Hello, how are you today?")

And here is the error:

OSError: [E941] Can't find model 'en'. It looks like you're trying to load a model from a shortcut, which is deprecated as of spaCy v3.0. To load the model, use its full name instead:

nlp = spacy.load("en_core_web_sm")

For more details on the available models, see the models directory: https://spacy.io/models. If you want to create a blank model, use spacy.blank: nlp = spacy.blank("en")

It would be helpful if someone finds a solution for this. Thanks.

Answer 1

Make sure you actually have the right spacy model installed. For example, install en_core_web_sm with the python -m spacy download en_core_web_sm command in the terminal.

Next, fix this error:

File "C:UsersUSERAppDataLocalProgramsPythonPython37libsite-packageschatterbottagging.py", line 13, in __init__
    self.nlp = spacy.load(self.language.ISO_639_1.lower())

That is,

Open the C:UsersUSERAppDataLocalProgramsPythonPython37libsite-packageschatterbottagging.py file
Go to Line 13
Replace self.nlp = spacy.load(self.language.ISO_639_1.lower()) with

if self.language.ISO_639_1.lower() == 'en':
    self.nlp = spacy.load('en_core_web_sm')
else:
    self.nlp = spacy.load(self.language.ISO_639_1.lower())

You will need to add more conditions for other languages you need to support.

Answer 2

Check the version of spacy you are using.

Install spacy and download the language model, en_core_web_sm, in this case using

 python -m spacy download en_core_web_sm

If it is v3.0, you will need to load it using

nlp = spacy.load("en_core_web_sm")

If it is < v3.0, you can link the model creating a shortcut using

python -m spacy link en_core_web_sm en

and thus load it using nlp = spacy.load("en")

Answer 3

First, you need to download en_core_web_sm by running: python -m spacy download en_core_web_sm

You need to modify the following code.

Answer 4

In addition to the other comments, please be aware of an issue with SpaCy 3.0.3 and Python 3.8 – if these are the versions you’re using, you may have to download the language model via Python shell, ex.:

import spacy
from spacy.cli.download import download
download(model="en_core_web_sm")

For these versions, downloading via python -m spacy download en_core_web_sm may result in exceptions – as described ex. here.

Answer 5

Try just install the spacy with >>pip install -U spacy

And change the code

self.nlp = spacy.load(self.language.ISO_639_1.lower())

in "C:UsersUSERAppDataLocalProgramsPythonPython37libsite-packageschatterbottagging.py" to

  if self.language.ISO_639_1.lower() == 'en':
     self.nlp = spacy.load('en_core_web_sm')
  else:
    self.nlp = spacy.load(self.language.ISO_639_1.lower())

Get work for me here and I had the same problem

Answer 6

For Linux and Mac users :

To the above top-voted answer I will add that the location of tagging.py is :

/usr/local/lib/python3.7/site-packages/chatterbot

To be more precise :

<Install_path_of_Python>/site-packages/chatterbot

( The install path could be your virtual environment path as well )

Try just install the spacy with pip install -U spacy

And change the code

self.nlp = spacy.load(self.language.ISO_639_1.lower())

in C:UsersUSERAppDataLocalProgramsPythonPython37libsite-packageschatterbottagging.py to

if self.language.ISO_639_1.lower() == 'en':
   self.nlp = spacy.load('en_core_web_sm')

Answer 8

if downloading the package doesn’t work as follows:

python -m spacy download en_core_web_sm

then you don’t need to change the code in the package, just change the cause.

from chatterbot import languages

languages.ENG.ISO_639_1 = "en_core_web_sm"

it will change "en" to "en_core_web_sm" for spacy
