SpaCy

Directly from the "Downloading models" section of their github:

To increase transparency and make it easier to use spaCy with your own models, all data is now available as direct downloads, organised in individual releases. spaCy 1.7 also supports installing and loading models as Python packages. You can now choose how and where you want to keep the data files, and set up "shortcut links" to load models by name from within spaCy.

# pip install .whl or .tar.gz archive from path or URL
pip install /Users/you/en_core_web_sm-3.0.0.tar.gz
pip install /Users/you/en_core_web_sm-3.0.0-py3-none-any.whl
pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.0.0/en_core_web_sm-3.0.0.tar.gz
pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.0.0/en_core_web_sm-3.0.0-py3-none-any.whl

It's worth noting running python -m spacy download en_core_web_sm really just launches pip in a subprocess in this case.

Initially I downloaded two en packages using following statements in anaconda prompt.

python -m spacy download en_core_web_lg
python -m spacy download en_core_web_sm

But, I kept on getting linkage error and finally running below command helped me to establish link and solved error.

python -m spacy download en

Also make sure you to restart your runtime if working with Jupyter. -PS : If you get linkage error try giving admin previlages.

The SSLError you encountered when trying to download en_core_web_sm with spacy download indicates a problem with the SSL certificate verification while trying to access the package over HTTPS. This issue may indeed relate to your network's security setup, such as the presence of a proxy or firewall.

Since you've downloaded the en_core_web_sm-3.7.1.tar.gz file manually, you should be able to install it directly with pip, provided you supply the correct path to the file. The error message you're seeing suggests that the command might have been pointed to a directory instead of the tar.gz file, or the path was not specified correctly.

Here's how you can install the spaCy model en_core_web_sm-3.7.1.tar.gz file using pip:

1. Navigate to the directory where you've downloaded en_core_web_sm-3.7.1.tar.gz.
2. Run the following command, replacing path/to/en_core_web_sm-3.7.1.tar.gz with the actual path to the tar.gz file you've downloaded:

pip install /path/to/en_core_web_sm-3.7.1.tar.gz

Make sure to include the full file name, including the extension .tar.gz. Here’s an example if the file were in your current directory:

pip install ./en_core_web_sm-3.7.1.tar.gz

Give this a try and let me know if it resolves your issue. If you're still facing trouble, please ensure that the file path is correct and that the file is not corrupted. You can also try to install the package in a Python virtual environment to avoid potential conflicts with other installed packages.

en_core_web_md doesn't exist as a package in its own right on pypi.org or Anaconda, so you can't just pip install it by name. However you can find download links for the model on the GitHub page and you can pip install directly from one of the download URLs, e.g.

pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_md-2.0.0/en_core_web_md-2.0.0.tar.gz

Note that when I tested that it did install spacy for me. So it might be easiest to just use spacy to download in the first place and change the linked model with python -m spacy link afterwards if necessary.
