SSL: CERTIFICATE_VERIFY_FAILED error while downloading python -m spacy download en

Question

I have downloaded spacy in Anaconda prompt by using conda install -c conda-forge spacy. But when I tried to download en_core_we_sm using python -m spacy download en_core_web_sm I getting SSL: CERTIFICATE_VERIFY_FAILED error.

Answer 1

With HTTPS, trying to download something from a remote host produces an SSL connection error in some cases like if your computer is behind a proxy which does not let you to make SSL connection freely. For those cases, a downloading manager like pip , conda for python or apt-get or yum for Linux provide some options for a user to specify certificate for such connections or to allow untrusted communication with a remote host for such downloads.

However, downloading a model VIA spacy with python -m spacy download does not provide such options. You cannot add any SSL certificates nor specify trusted host for a download.

Fortunately, there's a workaround solution with two separate steps , downloading and installing. That is, download the model with any other clients which is under control with SSL (browser, curl, wget...) then install the downloaded model with pip install

Find appropriate model you need on https://github.com/explosion/spacy-models/releases and download tar.gz file like,

wget https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.5/en_core_web_sm-2.2.5.tar.gz

Then install it like,

python -m pip install ./en_core_web_sm-2.2.5.tar.gz

Answer 2

The answer provided by K. Symbol is helpful. As an alternative, the download and installation can be done in one statement with pip. Pip can be assigned "trusted-host" and the "install" object can be a website, so:

pip --trusted-host github.com --trusted-host objects.githubusercontent.com install https://github.com/explosion/spacy-models/releases/download/en_core_web_md-3.4.0/en_core_web_md-3.4.0.tar.gz

Answer 3

Just download the direct version.

python -m spacy download en_core_web_sm-2.2.0 --direct

I had the same error as you, gave this a try, and it worked. For more information here are some additional details from the model page: https://spacy.io/usage/models

Answer 4

For me the issue was i was running the command "python -m spacy download en" from a different location other than "C:\WINDOWS\system32". When i ran the command from "C:\WINDOWS\system32" with "Run as Admin" it worked like charm. Seems from other locations it is not able to load the correct ssl config.

Answer 5

If you are unable to download it because you cannot verify the certificate as you are behind a company proxy, you can also do the following by first downloading the file via requests and specifying that you don't want to check certifictates, then install it via pip:

import requests, os

lang = 'en'
r = requests.get(f'https://github.com/explosion/spacy-models/releases/download/{lang}_core_news_sm-3.0.0/{lang}_core_news_sm-3.0.0-py3-none-any.whl',
                 verify=False)  # verify=False to skip checking of certificate
file = f'{lang}_core_news_sm-3.0.0-py3-none-any.whl'
with open(file,'wb') as output_file:
    output_file.write(r.content)  # save the wheel locally
# then install it via pip
!pip install {file} --user  
os.remove(file)  # remove the file

Answer 6

First, Uninstall Spacy and clean the directories. Then install with the following link -

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org spacy

Use pip3 for Python3 and run following in a terminal

python -m spacy download en_core_web_sm

let me know if you still get error/s. Follow https://spacy.io/usage/models
