@ashwinvaidya17 thanks for the prompt PR! Could you fetch the latest master into your branch? Does the code style failure look reasonable, or we can think of changing the CI script?

[ashwinvaidya17]

It flags the make.bat file. I didn't write it. It was autogenerated by sphinx. My next goal is to slowly add pre-commit checks across the repo.
