> It seems that after the Python refactoring PR [https://github.com/apache/arrow/pull/13311] (ARROW-16340) Python is unable to find {{arrow_python}} even though the library it is imported into the correct directory.
> Currently this issue is fixed with setting an additional environment variable:
> {code:}
> CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1
> {code}
> We need to investigate further why this error is happening after the [refactoring|https://github.com/apache/arrow/pull/13311] and make sure Python is able to find the libraries on Windows without the additional env vars being specified.
