Full Changelog: 1.20.9...1.20.10

1.20.9

• Tile, Reshape
  • Tensor processing of dynamic shapes is supported.
  • Due to the experimental implementation, regression testing is still insufficient. However, this ONNX is ready for conversion.
  • daquexian/onnx-simplifier#323
  • src_ocr.onnx.zip
  • https://github.com/PaddlePaddle/PaddleOCR
  • Input: [N, 3, 32, W]]

1.20.7

• Optimization of torch.nn.PixelUnshuffle.

  • https://pytorch.org/docs/stable/generated/torch.nn.PixelUnshuffle.html
  • https://www.tensorflow.org/api_docs/python/tf/nn/space_to_depth
  • This implementation is inspired by the valuable knowledge of AlexanderLutsenko / nobuco. Thank you very much.
    • https://github.com/AlexanderLutsenko/nobuco?tab=readme-ov-file#implementation-mismatch-pick-your-poison
  • Unlike PyTorch's method of replacing internal processing, a similar process is implemented from a frozen ONNX graph with the minimum number of operations required.

  ONNX	Before tflite	After tflite

• Bug fix. ReduceL1, ReduceL2, ReduceLogSum, ReduceLogSumExp, ReduceMax, ReduceMean, ReduceMin, ReduceProd, ReduceSum, ReduceSumSquare

What's Changed

• Optimization of torch.nn.PixelUnshuffle by @PINTO0309 in #621

Full Changelog: 1.20.6...1.20.7

1.20.6

• MaxPool, AveragePool
  • Improved conversion stability when H, W and D of MaxPool and AveragePool contain undefined dimensions.
  • The accuracy of the converted model is not always accurate.
  • e.g. YOLOvNn dynamic inputs [N, 3, H, W]
  • YOLOvN has been modified only to avoid a situation where the conversion aborts, although this is undoubtedly not good for the design of the model, as fixed parameters such as the number of classes are embedded in the backward Split operation with fixed values.
  • Concatenating dimensions that have completely different meanings is also a major problem.
  • Unless you replace the PyTorch implementation with Slice, you won't be able to do proper inferencing.
