I've been trying to work with github-linguist for a while and it still gives a bit of problem.
After a few days of trying to figure out different issues with the language statistics, I managed to set .githubattributes with the right commands to get the correct statistics from github-linguist command:

But in GitHub's webpage/server it's still not showing up:

This is the link to the repo I am working on: https://github.com/FeriBolour/cotton-phenotyping
I tried different solutions:
- Waited almost a week.
- Pushed meaningless stuff to the repo to update the server.
It's still not working. What do you suggest me to do.
It could be two things:
In your case, it's not problem 1 because you appear to have only one branch on this repository. It's most likely problem 2. You can contact GitHub support and they should have a way to manually trigger a statistic update for your repository.
