How to set initial_chunk_size_bytes for CUDAExecutionProvider?

[smallbraingames]

In the ONNX docs here https://onnxruntime.ai/docs/get-started/with-c.html there is a setting, initial_chunk_size_bytes, that configures the BFC Arena allocator.

There doesn't seem to be an ort way to set this, and with_arbitrary_config fails on CUDAExectionProvider with Parse Unknown provider option: \"initial_growth_chunk_size_bytes\".\n"

What is the right way to do it?

ort currently doesn't have a safe ArenaCfg wrapper, though even if it did it seems like OrtCUDAProviderOptionsV2 doesn't support taking an ArenaCfg; only the legacy version does. The only option here might be to use the unsafe API directly.

Appreciate the prompt answer.

unsafe it is, it is time to live a little
