Yes, they are. But Cython is designed to show the source line number when there are errors. So this has been compiled. That error is vaguely familiar to me, I got it recently— I think the fix was to clean out and recompile the Cython files. However, if Pandas is working outside py2app, then it did get built properly. I’d look at the app bundle and see what’s different from the regular install. Ideally, it would copy only the complied modules. -CHB and I think these need to be compiled on installation (which should have > happend during py2app?). > > When you google for “pandas py2app” you’ll find people reporting similar > (but not identical) problems to what you report. > > But note that some of the stuff google finds is very old, so use your > common sense, the world may have changed a lot since the link was written. > > > > On 15 Jun 2021, at 23:37, Paul Fishback <fishb...@mail.gvsu.edu> wrote: > > I'm using Python 3.9 on a Mac running Big Sur and am trying to create an > app, MyApplication.app, from a script using py2app. I'm following the > process outlined at https://py2app.readthedocs.io/en/latest/tutorial.html . > The app itself uses tkinter for creating a GUI.
