Troubleshooting

make sure the downloaded Meshroom files are not corrupted (incomplete/interrupted download)

avoid special characters/non-ASCII characters in Meshroom and images file paths (#209)

make sure your antivirus program does not interfere with Meshroom ((#178)/(#342))

are you running Meshroom as Admin? (This will disable drag-and-drop on windows)

Check your Python installation /reinstall as admin and check the PATH if there are any conflicts

update/install latest NVIDIA drivers

set your NVIDIA GPU as primary GPU for Meshroom. (NVIDIA Control Panel Manage 3D Settings)

Try the Meshroom 2018.1 release; when using windows 7 try the corresponding release (Meshroom 2019.1 has some problems with Texturing #449, DepthMap and some photo datasets which worked in 2018.1 #409. These problems will be addressed in the next release)

Test Meshroom with the Monstree dataset

Sometimes the pipeline is corrupted. Clear the cache for the node (and following nodes) with the error. Sometimes restarting the application / the computer might help. #201

check your images for problems
