Question

There is only one input file given for the MNIST model. Where can I quickly get more? Do I need to generate it myself?

Further information

Is this issue related to a specific model?
Model name (e.g. mnist): MNIST
Model opset (e.g. 7): any

Also, the test data has negative numbers in it when parsed with the snippet from the main onnx/models README.md. According the the MNIST model readme, the inputs were generated by scalling the color value (0 to 255) to [0, 1.0]. Is this a bug?

See https://github.com/microsoft/onnxruntime-inference-examples/blob/main/c_cxx/MNIST/MNIST.cpp for a full example.
