@liqunfu could you try copying the onnxruntime dll to the same directory as the sln file or the unit_test.exe file?

Thanks @baijumeswani, it works if I copy over onnxruntime.dll to the exe's folder. The issues is caused by having a onnxruntime.dll at "C:\Windows\WinSxS\wow64_microsoft-windows-ai-machinelearning_31bf3856ad364e35_10.0.22621.1_none_7056cab181ea1d5c\onnxruntime.dll". it must be a very old version. It blocks use and develop ort-genai on windows machines. This need to be fixed.

I see it is also confusing work with ort-genai's python api. It used to having a onnxruntime.dll at the genai install location. Now it also uses onnxruntime.dll at onnxrutime's install location. It is hard to know which one is being used.

[baijumeswani]

Ideally, the python build script will try to add the onnxruntime dlls to the same path as the exe:

onnxruntime-genai/build.py

Lines 565 to 567 in 53e3ac9

	lib_dir = args.build_dir / "test"
	if not args.ort_home:
	_ = util.download_dependencies(args.use_cuda, args.use_rocm, args.use_dml, lib_dir)

But I think on windows, we need another folder at the end of the path. If you have bandwidth, would you consider submitting a PR for this? If not, I can get to it.

For python, we load onnxruntime from inside onnxruntime's python package. Two reasons for this:

• Minimize the onnxruntime-genai package size
• Avoid problems where users want to use both ort and ort-genai together (since only one dll can be loaded at any given time).
