Any help on this would be appreciated. Thank you!

Looks like a network issue, not being able to reach pypi.org. Doesn't seem specific to NeMo Guardrails. Can you try again? Maybe it was something temporary.

[Suma-Rajashankar]

Yes, you are right, it was a network issue. Also, I realized we cannot install annoy in a virtual environment. Is that how it works? I set the include-system-site-packages = true and I could install annoy and nemoguardrails. Thank you @drazvan !

[drazvan]

You should be able to install annoy in a venv. I'm not sure why it did not work for you. Annoy does need to compile some code written in C, so maybe in your specific setup there was an issue inside the venv, but it's hard to know why. I'm glad you have a workaround.
