问题
I have an app that uses the Spacy model "en_core_web_sm". I have tested the app on my local machine and it works fine.
However when I deploy it to Heroku, it gives me this error:
"Can't find model 'en_core_web_sm'. It doesn't seem to be a shortcut link, a Python package or a valid path to a data directory."
My requirements file contains spacy==2.2.4.
I have been doing some research on this error and found that the model needs to be downloaded separately using this command:
python -m spacy download en_core_web_sm
I have been looking for ways to add the same to my requirements.txt file but haven't been able to find one that works!
I tried this as well - added the below to the requirements file:
-e git://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz#egg=en_core_web_sm==2.2.0
but it gave this error:
"Cloning git://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz to /app/.heroku/src/en-core-web-sm
Running command git clone -q git://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz /app/.heroku/src/en-core-web-sm fatal: remote error: explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz is not a valid repository name"
Is there a way to get this Spacy model to load from the requirements file? Or any other fix that is possible?
Thank you.

Add this in your deployment step, if using docker add in Dockerfile
pip3 install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.5/en_core_web_sm-2.2.5.tar.gz --user
EDIT
Add
spacy>=2.2.0,<3.0.0
https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz#egg=en_core_web_sm
in requirements.txt

Ok, so after some more Googling and hunting for a solution, I found this solution that worked:
I downloaded the tarball from the url that @tausif shared in his answer, to my local system.
Saved it in the directory which had my requirements.txt file.
Then I added this line to my requirements.txt file: ./en_core_web_sm-2.2.5.tar.gz
Proceeded with deploying to Heroku - it succeeded and the app works perfectly now.
