Known issues

Change `import nat_core` to `from nvidia_nat_core import ...`.

affects: <=1.4.0

breakingRequires Python 3.11+. Older Python versions will cause installation failure.

fix

Upgrade Python to 3.11 or higher.

gotchaAPI key must be set via environment variable `NVIDIA_API_KEY` or passed in config; otherwise agent creation fails silently.

fix

Set `NVIDIA_API_KEY` environment variable or pass `api_key` in `AgentConfig`.
