NVIDIA NeMo Fabric Hermes Agent Adapter
nemo-fabric-adapters-hermes provides a NeMo Fabric adapter for use with Hermes Agent.
Install
The adapter supports Python 3.11 through 3.14. The pinned upstream Hermes revision requires Python 3.14 and Relay 0.10 on supported platforms. Hermes Agent 0.20 and later is not installable from PyPI. Follow the Hermes Agent installation guide, then install the NeMo Fabric packages into the same Python environment.
The following table shows which NeMo Fabric components each package expression provides. None of these expressions installs Hermes Agent:
| Installation | Runtime | Adapter | Harness | NeMo Relay Python Package |
|---|---|---|---|---|
pip install nemo-fabric nemo-fabric-adapters-hermes |
Yes | Yes | No | No |
pip install "nemo-fabric-adapters-hermes[full]" |
No | Yes | No | Yes |
pip install "nemo-fabric-adapters-hermes[relay]" |
No | Yes | No | Yes |
pip install nemo-fabric-adapters-hermes |
No | Yes | No | No |
Released Hermes Agent v2026.9.24 requires Relay 0.8.x. Ordinary runs remain
supported in a separate environment. Relay telemetry and streaming require a
Hermes build compatible with the chosen Relay version. Until a compatible
release is available, NeMo Fabric tests a merged upstream revision that
requires Relay 0.10 on supported Python 3.14 platforms. Use the relay and
full extras only with a compatible Hermes checkout. The adapter fails at
startup if Relay telemetry is enabled with an incompatible Hermes or Relay
installation.
Refer to the installation guide for more details.
