Common Errors

1. ImportError: No module named ecto

• Make sure your environment variables are set correctly. You can replace python run.py with ./run.sh followed by your normal parameters and that will set the environment variables for that run.

2. [ERROR] You must put your pictures into an <images> directory

• Your project path must look like this:

/home/user/odm_data/
|-- images
    |-- IMG_0001.jpg
    |-- IMG_0002.jpg
    ...
|-- gcp_list.txt
...

3. ImportError: No module named csfm

• Your install of OpenSfM may have failed. You can reinstall it manually:

cd /path/to/OpenDroneMap/SuperBuild/src/opensfm
python setup.py build

4. [ERROR] quitting cause: /code/SuperBuild/install/bin/pmvs2 /code/pmvs/recon0/ option-0000 returned with code 35072.

• The most likely reason for this error is that you ran out of memory. You can upgrade your RAM or adjust your CMVS/PMVS settings for better memory management:

  • --resize-to will reduce the size of the images and the overall memory cost
  • Reduce --cmvs-maxImages to the smallest number possible without causing CMVS to run on an infinite loop. This will take trial and error, though.

5. OpenSfM is taking a really long time

• If you are using a hyperthreaded processor, you will have to reduce the number of cores OpenSfM uses to the number of physical cores you have (or fewer). This is trivial on a vagrant machine: in your Vagrantfile, reduce the cores allocation to 1 or 2 minus the number of physical cores you have. Otherwise, you will
