Full Changelog: 1.25.7...1.25.8

1.25.7

• Expand, BatchNormalization, Gather
  • Automatic accuracy compensation.
  • Added the ability to automatically compensate for accuracy degradation due to dimensional transposition errors.
• AveragePool

  • Only very few edge cases are supported.

  • The dynamic tensor AveragePool is difficult to replace exactly with TensorFlow's AveragePooling.

  • I have fixed and released the critical problems except for AveragePool, but AveragePool (with ceil_mode=1) with dynamic tensor as input is extremely difficult to fix due to compatibility issues with TensorFlow.

  • The problem is that the error was not occurring in the AveragePool (with ceil_mode=1) where the conversion error should have occurred, and the latest onnx2tf should now generate a conversion error in the AveragePool (with ceil_mode=1).
