ONNX is an open format to represent deep learning models and enable interoperability between different frameworks.

ONNX

The Open Neural Network Exchange (ONNX) is an open-source artificial intelligence ecosystem. With ONNX, AI developers can more easily move models between state-of-the-art tools and choose the combination that is best for them. ONNX is widely supported and can be found in many frameworks, tools, and hardware. It is developed and supported by a community of partners.

the results of mlmodel using ANE is wrong, but results of gpu and cpu are correct

There is a strange problem about my fcn-mobilenetv2 mlmodel. I convert this mlmodel from onnx using onnx-coreml tool with target=ios12. It can run on ANE because the speed is much faster than CpuAndGpu. However the results of ANE are totally wrong,…

how do I change all pertinent instances of uint8 to int8 in my tensorflow model

I am converting a frozen pb model to onnx, but onnx does not support uint8. How do I go about replacing uint8 with int8 in the model file? I can also retrain if I have to, but I am not sure which file to modify and how. I would have guessed that I…
