[Build] ModuleNotFoundError: No module named 'onnxruntime.capi'

[lzivan]

Describe the issue

Hi team,

I'm using CPU build from source.

.\build.bat --config RelWithDebInfo --build_shared_lib --parallel --build_wheel --skip_tests

The build is successfully done. Now I'm using conda with python 3.11. The WHL file is under build\Windows\RelWithDebInfo\RelWithDebInfo\dist.

pip install onnxruntime-1.19.0-cp311-cp311-win_amd64.whl

However, when I'm running onnxruntime-python-api.py

It presents:

Traceback (most recent call last):
  File "C:\Users\arda\zijie\onnxruntime\onnxruntime-python-api.py", line 7, in <module>
    import onnxruntime
  File "C:\Users\arda\zijie\onnxruntime\onnxruntime\__init__.py", line 54, in <module>
    from onnxruntime.capi import onnxruntime_validation
ModuleNotFoundError: No module named 'onnxruntime.capi'

So I checked the site-packages of onnxruntime under conda envs, it does exist.

Please help, I'm not sure whether some packages are lost during the installation from whl.

I had the same problem when running python scripts from the onnxruntime git checkout, because it contains a folder named "onnxruntime" which gets confused with the onnxruntime package.

Thanks for the response. I changed the name of the onnxruntime folder under the git repo, and it won't give me "onnxruntime.capi" error. But now it says "Module onnx is not installed".

According to the error log, "onnx" is called under "torch". For "torch", I manually installed it by "pip install" after installing the WHL file. So for "onnx", do I need to manually install it by "pip install onnx"? Btw "onnx" is not installed after installing the WHL.

The above exception was the direct cause of the following exception:
