Exception: Child returned 137 - New here and trying to process my first job

Craig_Scott · 18 July 2020 14:47

Hi Everyone,

I’m new to the software and I apologize if I am missed something obvious I’m not sure if I am having a problem with my data set or my configuration since I’ve yet to successfully run a job.

These are the photos I am trying to proccess. A little research on the

" Exception: Child returned 137"

lead me to believe the maybe the project is too big. If this is the case does any recommendations to what I should use for my Docker advanced settings.

I will attach my log file below. Thanks so much in advance

Allocate more RAM to the docker environment (but leave at least 2-4GB for the host to run, don’t allocate 100%).

Craig_Scott · 18 July 2020 15:56

OK I will give that a try. thank you. Should I be resizing the images?

Craig_Scott · 18 July 2020 20:48

It worked! thank you so much for the suggestion. This software is very cool, can’t wait to dive it more

MelSaberi · 29 June 2021 01:32

I’m having the same problem with a dataset of 785 photos (P4P) and 6 GCPs. I’m on a 1TB HDD 32 GB RAM windows machine and never had issues with even larger datasets!

Trying to re-process with Lightning node hopefully it resolves but I’m still wondering what caused this. My docker keeps 2GB RAM for the host and allocates the rest to WebODM so there shouldn’t be a problem.

There is only one thing I can think of. There are about 16 photos out of 785 taken via POI circling around a structure but unfortunately the horizon is still visible in the photos. Would that be causing the issue?

Saijin_Naib · 29 June 2021 01:39

Yeah, trying to reconstruct the depth map for that might not be helping. I’ve noticed reduced memory usage in that part of the pipeline when I mask images with oblique/horizon data.

jportolese · 29 June 2021 03:40

I’ve had horizon issues as well and it has affected my processing. When you say mask do you mean crop the sky out of the images or do you actually do something else?

MelSaberi · 29 June 2021 04:40

Hmmm I knew that horizon would screw me Will see if Lightning can go over this hiccup otherwise I’ll just get rid of POI shots

Saijin_Naib · 29 June 2021 12:52

https://docs.opendronemap.org/masks/

I guess in theory it is pretty similar to cropping, but it is non-destructive to the original images.

If you have the time/patience, masking is pretty powerful. It might be worth trying if you need the extra scene detail

jportolese · 30 June 2021 02:38

Yeah that makes sense. I assume changing the footprint (width by height) of the photo might be an issue that would require a change to the exif data? Not sure as I haven’t really looked at what the exif contains. Does it include photo center or LL UR info? Either way cropping seems like a not so good idea.

Saijin_Naib · 30 June 2021 02:51

Not sure, to be honest. I wouldn’t change the image footprint, however.
