No Module Named CV 2

[digitalurban]

Afternoon - while trying to work out why my thumbnails for the timelapses are not working (my web server does have a thumbnails dir)... i noted a ModuleNotFoundError: No module named 'cv2' error which i thought might be useful to flag? Using the Dev branch:

endOfNight.sh: ===== Timelapse complete
*** upload.sh: ERROR: '/thumbnails' directory not found!
Traceback (most recent call last):
File "/home/pi/allsky/scripts/flow-runner.py", line 39, in

@digitalurban Andy, are you using the dev versions of both Allsky and the Allsky Website? They go together.
If so, what's in your ftp-settings.sh file for VIDEOS_DIR?

[digitalurban]

Aw, i went the upgrade route and thus have not installed the new version of the website - thanks for flagging!

[EricClaeys]

@digitalurban. Andy, if you already had an Allsky Website on your Pi, the installation should have displayed a notice that you need to update it. Was that the case for you?

[EricClaeys]

Andy, I can't tell if you updated the website or not. You need to run cd ~/allsky; website/install.sh --branch dev to get the new test website.

It looks like the allsky/tmp directory has bad permissions. Please do the following:

cd ~/allsky
ls -ld tmp
ls -ld tmp/*
mount | grep -I allsky

Then attach your ftp-settings.sh file, after removing the password.

Also, you should never run any allsky commands using sudo since it may set permissions or owner / group such that the Pi login won't be able to work correctly.

[digitalurban]

Just run the commands - thanks for taking the time - noted the don't use sudo - makes perfect sense!

@digitalurban Andy, Allysky tries to upload video thumbnails to the ${VIDEOS_DIR}/thumbnails directory on your remote server.
As a simple test, try the following:

• stop Allsky: systemctl stop allsky
• run sudo truncate -s 0 /var/log/allsky.log
• create a directory called allsky/images/test
• copy about 50 .jpg files from any of the other allsky/images/DATE directories to the test directory
• run generateForDay.sh -t test to generate a timelapse for the files in the test directory
• follow the instructions to upload the video, which will also upload the thumbnail
• look in the log file for any errors
• restart Allsky

[digitalurban]

Thanks for the reply - i will give this a try - as a side note, i run 2 allskys and did a complete fresh install on my other one - i get the same issue https://finchamweather.co.uk/allsky/ - so no thumbnails for timelapses - it might therefore be something to do with my server (although everything else works).

[EricClaeys]

@digitalurban Andy, do you have TIMELAPSE_UPLOAD_THUMBNAIL="true" (and TIMELAPSE_MINI_UPLOAD_THUMBNAIL="true" if you are creating mini-timelapse)?
If so, the thumbnails will be created on the Pi and uploaded to the remote server.

Also, would you please run ~/allsky/scripts/check_allsky.sh and post its results? It checks the sanity of various things.
Thanks

Andy

Are you getting the module error during 'normal' capture i.e. not just in the endofnight?

The error would imply the python cv2 module isn't installed.

Cheers

Alex

[EricClaeys]

@Alex-developer Alex, is install.sh supposed to install the python cv2 module?

[Alex-developer]

@EricClaeys yes it's the first entry in the requirements files.

[EricClaeys]

@Alex-developer Do you think the upload.sh ERROR and the cv2 error are related? I wouldn't think so.

[Alex-developer]

@Alex-developer Do you think the upload.sh ERROR and the cv2 error are related? I wouldn't think so.

@EricClaeys No I don't think so. The cv2 error is coming from the flow runner which is the last thing the end of night script does.

I'll have a look at the cv2 error but I cannot see how it's could be related to the upload error, it's just two different issues in the log

It looks like the error is caused by a missing OpenCV module, which is needed for thumbnail generation. You can try installing OpenCV by running the following command in the terminal
