Error during feature extraction

[tintin15634145]

I've successfully done every step and the project went up and smooth. But when I'm processing the images, it showed "Error during feature extraction." I've seen the images have been successfully downsized, but there's nothing in sparse folder.

I'm using the following options:
Image Scaling Option: 1600k
COLMAP Feature Matching Type: Exhaustive

The process log showed as follow:

=== Image Preparation ===

And in terminal, I can see this:

Error during feature extraction.

I think I know the problem. It's because my pathname has space in it. I substituted them with underline and it ran successfully.
Thank you. :)

I think a way to check it is probably see whether the pathname copied has single quotation marks. If don't, then it's fine. Otherwise you need to adjust the pathname.
