Starting from this release, all ONNX Runtime CPU packages are now built without OpenMP. A version with OpenMP is available on Nuget (Microsoft.ML.OnnxRuntime.OpenMP) and PyPi (onnxruntime-openmp). Please report any issues in GH Issues.
Note: The 1.7.0 GPU package is uploaded on this Azure DevOps Feed due to the size limit on Nuget.org. Please use 1.7.1 for the GPU package through Nuget.
Key Feature Updates
General
Mobile
Custom operators now supported in the ONNX Runtime Mobile build
Added ability to reduce types supported by operator kernels to only the types required by the models
Expect a 25-33% reduction in binary size contribution from the kernel implementations. Reduction is model dependent, but testing with common models like Mobilenet v2, SSD Mobilenet and Mobilebert achieved reductions in this range.
Custom op support for dynamic input
MKLML/openblas/jemalloc build configs removed
Removed dependency on gemmlowp
[Experimental] Audio Operators
Fourier Transforms (DFT, IDFT, STFT), Windowing Functions (Hann, Hamming, Blackman), and a MelWeightMatrix operator in "com.microsoft.experimental” domain
Native support added for additional pixel ranges [0..1] and [-1..1] in image models.
A new property is added to the ImageFeatureDescriptor runtimeclass to expose the ImageNominalPixelRange property in ImageFeatureDescriptor. Other similar properties exposed are the image’s BitmapPixelFormat and BitmapAlphaMode.
