Next sections highlight the main functions used to build an ONNX graph with the Python API onnx offers. ONNX defines a common set of operators - the building blocks of machine learning and deep learning models - and a common file format to enable AI developers to use models with a variety of frameworks, tools, runtimes, and compilers. Polygraphy API Reference Polygraphy is a toolkit designed to assist in running and debugging deep learning models in various frameworks. Where is this sample located? ONNX with Python¶. ir_version property MUST be present in every model. In addition to creating nodes, this function can also create the input and output tensors, and automatically insert the node GreaterOrEqual - 12¶ Version¶. layer() and graph. 其他相关代码2. doc_string (str) – A doc_string for the graph. Just authenticate like you always do, and we'll forward the credentials on the first request.
