!pip install -q torchmetrics -U mlxtend
In the above code, what does -q and -U stand for? What is their meaning?

Thanks

Hi @Durga-33,

Good question!

-q stands for "quiet" as in there won't be any outputs when installing the package.

And -U stands for "update" as in, get the latest version of the package if it's already installed (for example, if package version 1.0.0 is installed but 1.0.2 is available, remove 1.0.0 and install 1.0.2).

Thanks a lot, Sir!
