Persisting spaCy import error: NotOpenSSLWarning: urllib3 v2.0 only supports OpenSSL 1.1.1+

[vrunm]

I realize this is a recently common error, but none of the solutions I have found online helped me. I am trying to work with spaCy in Jupyter notebook and VScode on a Mac OS , but every time I try to import spacy, I get the following error:

NotOpenSSLWarning: urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'LibreSSL 2.8.3'. See: https://github.com/urllib3/urllib3/issues/3020
  warnings.warn(

I tried

brew install openssl@1.1

This didn't work so I then tried to downgrade urllib3 using

pip install urllib3==1.26.6

Didn't work either. I tried using a virtual environment, also didn't work. I've been scouring the web trying to find a solution but nothing seems to work.

This is not really a spaCy issue, but an issue with the Python installation. You could try to install an older version of urllib3, for instance, I have a virtual environment with a recent version of spaCy 3.5 and urllib3 1.26.15, which works fine:

pip install urllib3=1.26.15

If that doesn't work, please confirm with pip show urllib3 that that version was indeed installed and what error you are getting. Another option would be to build or install a Python version that is built against OpenSSL 1.1.1 or newer.

I tried

brew install openssl@1.1

This will usually not work, because Homebrew installs openssl as a keg-only, meaning that the library is not visible, unless you explicitly link against it. Secondly, the SSL module links against libressl, which most likely has a different shared library version. Finally, the SSL module could have the library paths hardcoded (it does on my installation).

This worked for me like a magic. Thanks

works like a charm. thanks.

The error message you're encountering indicates that urllib3 version 2 requires OpenSSL 1.1.1 or newer, but your Python environment is using LibreSSL 2.8.3. This incompatibility is causing the warnings and likely the subsequent failure.

You can resolve it by following below steps, I assume the device is MacOS

Step 1: upgrade OpenSSL

  brew update
   brew upgrade openssl
   brew link --force openssl

Step 2: Reinstall python with correct SSL

# Ensure pyenv is up-to-date
 brew update
 brew upgrade pyenv
 
 # Install Python with the correct OpenSSL
 env PYTHON_CONFIGURE_OPTS="--with-openssl=$(brew --prefix openssl)" pyenv install 3.9.x
 
 # Set the newly installed Python as the global version
 pyenv global 3.9.x

x is a place holder here, you can use like below

`env PYTHON_CONFIGURE_OPTS="--with-openssl=$(brew --prefix openssl@1.1)" pyenv install 3.9.13

`

Step 3: upgrade urllib3

`pip install --upgrade urllib3`

Step 4: verify the installation

python -c "import ssl; print(ssl.OPENSSL_VERSION)"

An another way to solve this problem:
Add export PYTHONWARNINGS=ignore to your .zshrc

This is not "solving" the problem, but ignoring it.
