@RahulDas-dev Does the source of D:\python\doc-inference\.venv\Lib\site-packages\wrapt\__init__.py match that in https://github.com/GrahamDumpleton/wrapt/blob/f3fa91652266a3a99912e0f8290b574827e845c6/src/wrapt/__init__.py#L13? It imports the AdapterFactory, so it should be available to deprecated which imports wrapt. It seems like there was an issue installing the packages. I notice you also filed #1633, where you don't seem to hit this issue. Did you manage to fix it, or is it only happening sometimes?

I removed the entire virtual environment and performed a fresh installation using uv install. The issue no longer occurs, and I'm currently struggling to reproduce it
