Frequently Asked Questions (FAQ)#

AMD Quark for ONNX#

Model Issues#

Issue 1:

Error of “ValueError:Message onnx.ModelProto exceeds maximum protobuf size of 2GB”

Solution:

This error is caused by the input model size exceeding 2GB. Set optimize_model=False and use_external_data_format=True.

Quantization Issues#

Issue 1:

Error of “onnxruntime.capi.onnxruntime_pybind11_state.RuntimeException: [ONNXRuntimeError] : 6 : RUNTIME_EXCEPTION : Non-zero status code returned while running Reshape node.”

Solution:

For networks with an ROI head, such as Mask R-CNN or Faster R-CNN, quantization errors might arise if ROIs are not generated in the network. Use quark.onnx.PowerOfTwoMethod.MinMSE or quark.onnx.CalibrationMethod.Percentile quantization and perform inference with real data.
