Check Fail When Data Preprocessing max_num_matches > 0 (0 Vs. 0) terminate called after throwing an instance of 'std::invalid_argument'

When I installed colmap following the steps for data preprocessing, I selected the cook_spinach data set as the preprocessing data set. But when I enter python scripts/pre_n3d_colmap.py --videopath cook_spinach
an error appears because the feature mater max_num_matches is 0, indicating that no matching feature points have been found
Could you tell me how to solve this problem?

I met the same issue. I used 'python scripts/pre_n3d.py. ' instead.
The difference between two python files is just you can't set stride by using parser.add_argument.

Thank you for your generous reminder!
I tried using the data preprocessing function pre_n3d.py in SpacetimeGaussians and it seemed to work fine

Hi, have you try the Technicolor dataset? I also met the same issue.
