trevor-m opened a new pull request #5731: URL: https://github.com/apache/incubator-tvm/pull/5731
TensorFlow batch norm op has two type attributes: `U` which is the type of the parameters scale, offset, mean, and variance. `T` which is the type of the input and output. The TF importer currently adds casts the input from `T` type to `U` type so that the computation is done in `U` type, and then casts the output back to `T`. However, it adds these casts even when `U` and `T` are the same. There ends up being many casts from float to float throughout the model which introduces issues for BYOCG. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
