  "description" : "This `onnx` resource loads and initializes a general (single file) ONNX model that processors\ncan reference. It handles downloading and caching of model files, as well as loading the necessary native libraries.\n\nSee the official ONNX [github repo](https://github.com/microsoft/onnxruntime) for more information.\n\n## Models\n\nSupports standard ONNX models (`.onnx` files) for various machine learning tasks including\nclassification, regression, and anomaly detection.\n\n## Downloads\n\nThe `modelUri` can point to a location on a local disk (using `file://` scheme) or on a remote storage.\nRemote storage support depends on available plugins, e.g., S3 plugin allows downloads from an S3-compatible bucket.\n",
