Cascade Training Error OpenCV 3.0.0 - Train dataset for temp stage can not be filled. Branch training terminated. Cascade classifier can't be trained. Check the used training parameters.
"Train dataset for temp stage can not be filled. Branch training terminated. Cascade classifier can't be trained. Check the used training parameters."
I checked same problem under it.

However, error still occurred in this system. Also, I use OpenCV 3.0.0 with Python 2.7.12 on Ubuntu16.04.

Train dataset for temp stage can not be filled. Branch training terminated.
Cascade classifier can't be trained. Check the used training parameters.
So, anyone teach me how to solve it?
There are tons of questions in this forum answering this. Use the search bar, and read
Thank you!
I already read them, to search "train dataset" and I understood cause which is nglist.txt isn't read. So, I tried it, for examle, I wrote absolute path in nglist.txt, but it isn't improved.
