[OpenDroneMap-users] Tips and tricks for model re-runs

[Frederic Muller]

Hi!

Just installed ODM and trying to have it run first. I'm using the images
GitHub of the project and specifically ran on COPR images.

Unfortunately it has failed twice with the same error message which is
"Error in OdmTexturing:
Error in OdmTexturing:
Failed to read image:
'/home/fred/Documents/odm_data/copr//IMG_0031.jpg'

I looked at the image and it opens fine, but maybe the problem comes
because of the double /?

Or is copr data set not ready?

Thank you.

Fred
