python spacy TypeError: unpackb() got an unexpected keyword argument 'raw'

Question

I'm using spacy for natural language processing with the following code in jupyter notebook.

# Import spacy
import spacy

# Instantiate the English model: nlp
nlp = spacy.load('en')

The following error occur

---------------------------------------------------------------------------

TypeError: unpackb() got an unexpected keyword argument 'raw'

To summarize it is

TypeError: unpackb() got an unexpected keyword argument 'raw'

Just a note: I have install and link spacy.load('en') properly in anaconda prompt as administrator python -m spacy download en already. Here's the result in anaconda prompt

(base) C:\WINDOWS\system32>python -m spacy download en
Requirement already satisfied: en_core_web_sm==2.0.0 from https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.0.0/en_core_web_sm-2.0.0.tar.gz#egg=en_core_web_sm==2.0.0 in c:\users\winsu\anaconda3\lib\site-packages (2.0.0)

    Linking successful
    C:\Users\winsu\Anaconda3\lib\site-packages\en_core_web_sm -->
    C:\Users\winsu\Anaconda3\lib\site-packages\spacy\data\en

    You can now load the model via spacy.load('en')

Answer 1

pip uninstall msgpack-python
pip install msgpack

Note that: my prompt happens to underscored that "regex version(2018.7.11) is incompatible with spacy which wants regex==2017.4.5" however my spacy still works normally now!

Btw, great thanks to @Ines Montani

Answer 2

I am using Conda Python 3 on a Windows Box. Installing spacy installed the msgpack:

Local\Continuum\anaconda3>conda list
# packages in environment at C:\Users\akmm94\AppData\Local\Continuum\anaconda3:
#
# Name                    Version                   Build  Channel
msgpack-python            0.5.1            py36he980bc4_0

and I got the same error doing:

import spacy
nlp = spacy.load('en')

Error:

TypeError: unpackb() got an unexpected keyword argument 'raw'

FIX: reinstalled msgpack-python using:

conda install -c anaconda msgpack-python

this updated msgpack-python:

msgpack-python:  0.5.1-py36he980bc4_0             --> 0.5.6-py36he980bc4_1 anaconda

and the error got fixed!
