Using auto-py-to-exe does not work with wetterdienst

[Philly-V]

Hello,

I am trying to create an .exe with auto-py-to-exe out of my Python script which uses wetterdienst to access wind and air pressure data from DWD stations around germany. To make it portable without using a virtual environment I tried to convert the script to an .exe. Executing the .exe throws the following error:

  File "main.py", line 10, in <module>
  File "<frozen importlib._bootstrap>", line 1027, in _find_and_load
  File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked

  File "environs\__init__.py", line 415, in read_env
  File "dotenv\main.py", line 253, in _walk_to_root
OSError: Starting path not found

Note that line 10 in main.py is:

from wetterdienst.provider.dwd.observation import DwdObservationRequest, DwdObservationDataset, DwdObservationPeriod, \
    DwdObservationResolution, DwdObservationParameter

It seems the error comes from wetterdienst using dotenv to access a path which is nonexistent (probably because the script was converted to an executable). Since I don't have much knowledge about the how dotenv works and ran most of my Python scripts inside the IDE I work with I am not sure if this is a wetterdienst-related problem, or rather a problem with auto-py-to exe or my limited knowledge about it, but maybe you can tell me if it is possible to convert the script to an .exe or if I rather should use a virtual environment to make it portable.

The script is working when executed inside an IDE and on another computer when all required packages are installed with pip (which is what I try to avoid).

Thanks in advance

Dear @Philly-V, it seems that this i neither a problem with wetterdienst nor with dotenv.

The error occurs in _walk_to_root which is typically for missing environment files. You have to take care of total paths.
Do you mount the env into the exe?

Please check this out and let us know if it works or not.

Best regards

Dear @Philly-V,

on your endeavor, you might be successful using PyInstaller ¹, see also GH-823.

With kind regards,
Andreas.
