NVIDIA NeMo Fabric Runtime

License GitHub Release

Diagram showing NeMo Fabric connecting applications, evaluation systems, and reinforcement learning rollouts to harnesses and custom agents, with results, artifacts, and telemetry as outputs.

nemo-fabric-runtime provides the Python SDK and native Rust bindings for NVIDIA NeMo Fabric, a runtime execution layer for agents.

Typically this is installed using the nemo-fabric meta package.

pip install nemo-fabric

Installing the runtime package directly is equivalent:

pip install nemo-fabric-runtime

For the default embedded NeMo Relay ATOF streaming path, install the runtime's streaming extra to include the matching collector:

pip install "nemo-fabric-runtime[streaming]"

The package exposes the nemo_fabric Python module for typed agent configuration, validation, run planning, runtime lifecycle management, normalized results, artifacts, diagnostics, and telemetry references.

Refer to the NeMo Fabric documentation for installation and usage guidance. Source code is available in the NVIDIA NeMo Fabric repository.

The package also installs fabric-agent-ctl, a command bridge and foreground runtime server for controlling one SDK runtime lifecycle inside one sandbox. Refer to the NeMo Fabric runtime server guide for SDK command mappings, runtime IDs, socket ownership, and sandbox lifecycle.
