Framework compatibility

Use this sub-skill when a request names TensorFlow 2, TensorFlow 1/Tensorpack, Keras or Keras-MXNet, Chainer, a framework-specific model provider, or a framework-specific training/evaluation/demo command.

Route first

1. Identify the requested backend and read the backend matrix.
2. Check optional dependencies without importing a large framework or touching the network. The matrix and troubleshooting define the package/distribution and import names.
3. Label the result bounded-unverified unless the caller supplies a separately verified backend environment. These four compatibility surfaces were not live-verified in this production run; do not report them as working merely because a provider or CLI exists.
4. For a no-network CPU smoke test or when an optional backend is absent, route to the verified CPU Gluon/PyTorch paths in model-inference. Route dataset-backed runs to training-evaluation.
5. Route any parameter conversion, TF2-to-TFLite export, or cross-framework checkpoint question to conversion after recording the backend gate.

Safe defaults

• Prefer pretrained=False, an empty checkpoint argument, one small synthetic input, and --num-gpus=0 for diagnostics. A pretrained flag can download weights and is not an offline smoke test.
• Run python <entrypoint>.py --help only to inspect a CLI. Do not start training, evaluate a downloaded dataset, or execute conversion tests while diagnosing availability.
• Do not infer CUDA support from a visible GPU, a CPU wheel, or a successful Python import. Require a matching framework/CUDA environment and a separate live verification.

For exact provider names, prepare_model signatures, entrypoint flags, and failure recovery, use the bundled references rather than expanding this router.
