error installing polyglot package in stack heroku-18 and python3.6.12 runtime - python-3.x

Question

I want to deploy a flask server that is capable of upload files and text pre-processing techniques using packages like spacy, polyglot, etc.
while installing the polyglot package in Heroku(i.e. stack Heroku-18) it's always throwing error like below
ERROR: Command errored out with exit status 1:
