@analytics20132333 it would be ‘pip install lxml’, not ‘pip install python-lxml’. Having said that, there’s really no reason to install kaggle cli on Windows - you can just use your browser to submit to Kaggle on Windows.
But I’m guessing this isn’t actually what you want - assuming that you’re doing your GPU training on Linux (i.e. an AWS instance), then you need to be installing kaggle CLI onto your GPU server, not into Cygwin. The purpose of Kaggle CLI is that it’s hard to navigate the Kaggle website and make a submission via your Linux server, so it’s generally easier to to submit through a command line interface (CLI). So you would type ‘pip install kaggle-cli’ into your bash shell on your server.
Does that make sense?
