PyInstaller .exe is producing Value Error when executed, error log traces it back to skimage.metrics import

Ask Question

I wrote a programm using the skimage library ( from skimage.metrics import structural_similarity ). It works just fine, also creating the .exe using PyInstaller ( pyinstaller name.py --debug=all -c --icon=icon.png --onefile ) shows no errors.

When executing the .exe via cmd however, the following Error log shows up:

Traceback (most recent call last): File "label_check.py", line 8, in <module> from skimage.metrics import structural_similarity File "<frozen importlib._bootstrap>", line 1007, in _find_and_load File "<frozen importlib._bootstrap>", line 972, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed File "<frozen importlib._bootstrap>", line 1007, in _find_and_load File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 680, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 850, in exec_module File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed File "skimage\__init__.py", line 74, in <module> File "lazy_loader\__init__.py", line 245, in attach_stub ValueError: Cannot load imports from non-existent stub 'C:\\Users\\hartpude\\AppData\\Local\\Temp\\_MEI167882\\skimage\\__init__.pyi' [9492] Failed to execute script 'label_check' due to unhandled exception! [9492] LOADER: OK. [9492] LOADER: Manually flushing stdout and stderr [9492] LOADER: Cleaning up Python interpreter.

So the problem seems to be the import of skimage.metrics.

I have tried using including the hidden import --hidden-import=skimage / --hidden-import=skimage.metrics and after some research I added a hook file "hook-scikit-image.py" to the directory containing the following, according to the source https://github.com/pyinstaller/pyinstaller-hooks-contrib/blob/master/src/_pyinstaller_hooks_contrib/hooks/stdhooks/hook-skimage.data.py :

from PyInstaller.utils.hooks import is_module_satisfies, collect_data_files, collect_submodules
# As of scikit-image 0.20.0, we need to collect the __init__.pyi file for `lazy_loader`, as well as collect submodules
# due to lazy loading.
if is_module_satisfies('scikit-image >= 0.20.0'):
    datas = collect_data_files("skimage.data", includes=["*.pyi"])
    hiddenimports = collect_submodules('skimage.data', filter=lambda name: name != 'skimage.data.tests')
I included it via: pyinstaller label_check.py --debug=all -c --icon=icon.png --onefile --additional-hooks-dir=C:\...path...\hook-scikit-image.py but still the same error occurs. I also noticed this just above the Error log posted above:
import 'skimage._shared.version_requirements' # <_frozen_importlib_external.SourcelessFileLoader object at 0x00000211562526A0>
\# lazy_loader not found in PYZ
\# code object from 'C:\\Users\\myusername\\AppData\\Local\\Temp\\_MEI167882\\lazy_loader\\__init__.pyc'
import 'lazy_loader' # <_frozen_importlib_external.SourcelessFileLoader object at 0x0000021156252880>
It seems like I am not the first one having the problem but the link in this thread unfortunately did not help me solve my issue: https://groups.google.com/g/pyinstaller/c/9trSWwpIh3E
It seems that my knowledge is not enough to undestand the maby already given solves and I would deeply appreciate any help, if more input is needed for that I am happy to provide it. Thank you in advance!
                Thanks, it seems to have solved this Problem. Now I am confronted with:  Traceback (most recent call last):   File "label_check.py", line 2, in <module>     import fitz   File "PyInstaller\loader\pyimod02_importers.py", line 352, in exec_module   File "fitz_init_.py", line 1, in <module> ModuleNotFoundError: No module named 'frontend' [4460] Failed to execute script 'label_check' due to unhandled exception!
