code speed problem #6
Comments
Hi, If you're using your own data, the problem can be: 1. your point clouds are big; 2. data loading seems slow (it takes 1.8s?). Best, |
emmmm The number of point clouds is about 1w, and the speed of reading point clouds accounts for 1.8s.I use TXT file to read。 There have a good way to read? |
One way to do it, it's maybe to precompute the neighbors using a kd-tree, and modify the database to have this at hand for each epoch. knn complexity it's n^2, so if your cloud is big, the implementation in python can take a while. Open3d has an efficient implementation |
I tested the code with my data. The running time was 4s, the computer was 1070, and the video memory was 8 gigabytes.What is wrong?Excluding the read data time, the network runs in 2. 2 seconds
