is there a issue in prepare_semantic3d.py?

[jscksy]

when i run that code,in "points.append(np.loadtxt(line, dtype=np.float32))" the "line" is a point,it cause error: FileNotFoundError: -6.69267368 -0.29421055 1.16930819 -1515.0000 169 186 204

这个问题你解决了么？ loadtxt 的那部分，我以为是我的文件路径不对

Don't use this rope for semantic3d,it's really bad.

The np.loadtxt() function does not accept a single line as input. It is used to load data from a file, not from a specific line. If you want to append a single line of data to points, you can create a list from the line and then append it. Add this:
line = line.strip().split()
before this line: "points.append(np.loadtxt(line, dtype=np.float32))"
