ZeroDivisionError: division by zero #26

代码里的数据集目录格式和Cylinder3D一样,数据集目录格式调整下就可以了。下面是代码,看看就明白了 |
Hi I also met this problem. I followed the data_prerare.md but the data structure is not the same as it in the code Actually in the code the data is organized as this SemanticKITTI\dataset\00\velodyne in this function, we cannot read any data, so the error will occur def absoluteFilePaths(directory):
for dirpath, _, filenames in os.walk(directory):
for f in filenames:
yield os.path.abspath(os.path.join(dirpath, f)) |
Hello, may I ask how you finally solved it |
Hello! I encountered an error while running the training file:

The code for running the training file is:

I would like to ask, what are the possible reasons for this error to occur? I have checked my dataset path and there should be no problem, but I am not sure what other reasons are. Thank you
