🔒 Problem with non-existing module which actually exists

[hallow plover]

Hi, I have a problem. I am using the library "dronevis" in python, a library for object detection algorithms trained on a specific dataset which, when I run my script and load a model, throws an error saying: "ModuleNotFoundError: No module named 'google_drive_downloader'". The problem is that this module actually exists, I uninstalled and reinstalled it, removed cache, restarted PC, but still I get this messsage. Did anyone ever have the same problem or any similar? Thanking you for your time!

How did you install the google_drive_downloader library?

[hallow plover]

I saw that there exists a module and loads smoothly called googledrivedownloader but there is not the google_drive_downloader which is inside the dronevis library and I do not know what to do

[hallow plover]

pip install googledrivedownloader but there does not exist the same with underscores

[fleet oracle]

try python -m pip instead of pip

Run the same install command again, and post the output here

[hallow plover]

Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement google_drive_downloader (from versions: none)
ERROR: No matching distribution found for google_drive_downloader

nzar@Nikos:~$ python -m pip install googledrivedownloader
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: googledrivedownloader in ./.local/lib/python3.10/site-packages (1.1.0)
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from googledrivedownloader) (2.25.1)```

The one with the underscores does not work, the other says that I already have it installed as it is also said by the simple `pip install`

[fleet oracle]

I've found the problem

googledrivedownloader has renamed their module from google_drive_downloader to googledrivedownloader, breaking dronevis

As a temporary fix, you can edit the /home/nzar/.local/lib/python3.10/site-packages/ezcrowdcount/utils.py file directly and replace google_drive_downloader with googledrivedownloader

Looks like you need to file an issue at both dronevis and ezcrowdcount, to hopefully fix it in a feature update. It would help if you file a PR as well

[hallow plover]

yes, that is what I just did, seems to work, thank you very much for your time

[fleet oracle]

👍 np; kind of stupid that googledrivedownloader just changed their module name, breaking literally everything that uses it

[hallow plover]

yes, and I am suffering as my main work is writting low level C code and distributed systems using java and I hate my life as I have to use python for some projects in univercity

[fleet oracle]

Hehe better get used to solving packaging problems like this 😉

Python is all packages and no code

[hallow plover]

Literally most developement time is just trying to install all the necessary modules and make them work with all the versions. I really hate it. It's just "complete the puzzle pieces" and it gets on my nerves not knowing exactly what happens under the hood with memory etc

[hallow plover]

@fleet oracle well now I got another problem 😅 . Now I get the following error (ImportError):

  File "/mnt/c/Users/nikos/Documents/drone_ODT/tracker/track.py", line 24, in <module>

ImportError: cannot import name 'GoogleDriveDownloader' from 'googledrivedownloader' (/home/nzar/.local/lib/python3.10/site-packages/googledrivedownloader/__init__.py)```

I have been searching for the class for a while now but I can not seem to find anything

I might be able to resolve this actually I think I am almost there
