Hey Konstantin,
After you click Load samples, how many frames does it say loaded?
What is the shape of the dataset(s) in the table?
(Feel free to paste a screenshot here if it's easier)
Hi Talmo,
Here is a screenshot of the cluster sampling window after i load samples and compute PCA.
Hey Konstantin,
Very bizarre error. I can't see anything in the code that would be an obvious reason why this is happening.
Try just skipping the PCA Preprocessing and just cluster without it -- it should still work, and if not it'll at least suggest a reason as to what's wrong.
OK I looked at the clusters and they were all identical. The reason was that my .h5 file was messed up and when i was creating it, I accidentally just saved the same frame 2709 times. So PCA had no variance in the video to work with.
Thanks for the troubleshooting tip!
Hi Talmo,
Suddenly encountering a new problem with LEAP.
during the cluster_samples program, the PCA computation step results in 90% of the variance explained in blank modes, where there are 0 modes. The matlab command prompt reads:
Warning: Columns of X are linearly dependent to within machine precision. Using only the first 0 components to compute TSQUARED.
Do you know what this could be caused by? I tried it with two different videos. I feel like I remember seeing this happen before but I can't remember exactly what where the circumstances.
Thanks!
