FYI, I've updated Cython's module import checks to include an interpreter check. This (multi-file) test shows the new behaviour, which is to raise an ImportError on module creation when it detects a different interpreter than during the initial import: https://github.com/cython/cython/blob/master/tests/run/reimport_from_subinterpreter.srctree The checks are implemented here (and called a bit further down in the module create function): https://github.com/cython/cython/blob/4ce754271ff4cfbd8df2b278e812154fb1b02319/Cython/Utility/ModuleSetupCode.c#L909-L932 I also added a test that should match the problem discussed here, which makes what I described appear as a viable solution (or work-around): https://github.com/cython/cython/blob/master/tests/run/reimport_from_package.srctree
