[GitHub] [tvm] merrymercy opened a new pull request #7030: [Frontend] Prevent tflite frontend from producing int64 shape
merrymercy opened a new pull request #7030:
URL: https://github.com/apache/tvm/pull/7030
I found some shapes and parameters (padding) are converted to int64 from tflite frontend.
It will result in a placeholder shape be `[1, (int64) 112, (int64) 112, 64]`. Some of them are int32, the others are int32.
This fails some optimization in the auto-scheduler.
This is because `ShapeAsNumpy` returns `np.int32`, but it is automatically upcasted to `np.int64` when doing computation. We convert all `np.int32` to python's int to prevent this auto upcast.
