## TL;DR

Reboot the instance first, then check the drivers.

## Fix

1. Reboot the instance first, then check the drivers.
   Expected: you can confirm this matches your situation.

## When to use

- You are setting up or using this Lambda GPU cloud feature.
- The symptom matches: GPU not detected means reboot and check drivers.

## When NOT to use

- Unrelated Lambda GPU cloud issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Compatibility

Reported against Lambda GPU cloud. Source: https://github.com/majiayu000/hermes-agent/blob/HEAD/optional-skills/mlops/lambda-labs/SKILL.md.

## Variant phrasings

### GPU not detected means reboot and check drivers

## Why it happens

torch.cuda.is_available() returning False on a Lambda instance is usually a driver state issue.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
