It looks like pyinstaller --collect-all mne mwe.py
is all it takes to build the example. On Monday, February 17, 2025 at 11:44:49 AM UTC+1 Clemens Brunner wrote: Hello! I'm trying to package a Python script which imports mne <https://mne.tools/stable/index.html>, a package that uses lazy loading (via the lazy_loader <https://pypi.org/project/lazy-loader/> package). To reproduce, create a script called mwe.py with the following content: import mne print(mne.sys_info()) Then run pyinstaller mwe.py, and try executing the generated app with dist/mwe/mwe. This gives the following error (I tried this on macOS): Traceback (most recent call last): File "mwe.py", line 1, in <module> import mne File "<frozen importlib._bootstrap>", line 1360, in _find_and_load File "<frozen importlib._bootstrap>", line 1331, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 935, in _load_unlocked File "PyInstaller/loader/pyimod02_importers.py", line 450, in exec_module File "mne/__init__.py", line 30, in <module> File "lazy_loader/__init__.py", line 342, in attach_stub ValueError: Cannot load imports from non-existent stub '/Users/clemens/Desktop/test-pyinstaller-pyi/dist/mwe/_internal/mne/__init__.pyi' [PYI-16568:ERROR] Failed to execute script 'mwe' due to unhandled exception! Any ideas/suggestions on how to make this work? I saw that skimage had a similar problem <https://github.com/pyinstaller/pyinstaller-hooks-contrib/pull/565>, but I don't know how to make it work for mne. Also, it seems like some packages have adopted lazy loading <https://scientific-python.org/specs/spec-0001/>, such as numpy and scipy, and it would probably be nice to have a solution that works for all of these packages.
