ModuleNotFoundError: No module named 'oiio.OpenImageIO'

Hi,

I just tested your setup on Windows and this is what I did:

$ git clone https://github.com/Correct-Syntax/py-oiio.git
$ cd py-oiio
$ vcpkg.exe install openimageio[pybind11]:x64-windows
$ cp <vcpkg>\current\installed\x64-windows\lib\python3.10\site-packages\OpenImageIO\OpenImageIO.cp310-win_amd64.pyd .\oiio\
$ mv .\oiio\OpenImageIO.cp310-win_amd64.pyd .\oiio\OpenImageIO
$ cp <vcpkg>\current\installed\x64-windows\bin\OpenImageIO.dll .\oiio\
$ cp <vcpkg>\current\installed\x64-windows\bin\OpenImageIO_Util.dll .\oiio\

$ python -c "import oiio"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\jhenry\git\py-oiio\oiio\__init__.py", line 16, in <module>
    from .OpenImageIO import *
ModuleNotFoundError: No module named 'oiio.OpenImageIO'

This is the file structure:

.
├── LICENSE
├── oiio
│   ├── OpenImageIO
│   ├── OpenImageIO.dll
│   ├── OpenImageIO_Util.dll
│   └── __init__.py
├── README.md
├── setup.cfg
├── setup.py
└── tests
    ├── img
    │   └── oiio-logo-with-alpha.png
    └── test.py

What did I miss?

Thanks!

Based on your directory structure, my guess is that you forgot to copy the dlls over.

@Correct-Syntax thanks for answering so quickly!

After I posted the issue, I just noticed that line in the readme. I tried copying all the dlls but it doesn't work either:

$ cp <vcpkg>\current\installed\x64-windows\bin\*.dll .\oiio\

$ python -c "import oiio"

(I also renamed OpenImageIO.cp310-win_amd64.pyd to OpenImageIO)

1. It may have something to do with where you are in your terminal. Try moving to the folder (if you aren't already there)
2. Copy this to your python site-packages dir oiio.zip. See if that works. If it doesn't then I will be extremely surprised.

Oh I'm sorry it's a dumb mistake, I renamed the .pyd file to OpenImageIO without the extension so it didn't work! Now it works with OpenImageIO.pyd

Thanks for your help ^^

You're welcome.
