Pull Request Overview

This PR changes the CUDA execution provider's convolution algorithm search from EXHAUSTIVE (0) to DEFAULT (2) to significantly reduce warmup time when using CUDA execution provider. This reverts a change that occurred during migration from nbigaouette/onnxruntime-rs to pykeio/ort.

  • Changed CUDAExecutionProvider configuration to use Default instead of Exhaustive algorithm search
  • Applied the change consistently across three different usage locations in the codebase
  • Addresses performance regression introduced during library migration

ちょうど24時間くらい前にcargo-codspeed v4.0.0がリリースされたことによってCIが落ちた。

@Sanzentyo 対処としてはこちらで別PRを作ろうと思うので、何もしなくてOKです。
