我要查档案预处理.py从这段来自https://github.com/intel-isl/Open3D-PointNet2-Semantic3D的windows10上的代码来看,原始代码在ubuntu上。你知道吗
import os
import subprocess
import shutil
import open3d
from dataset.semantic_dataset import all_file_prefixes
def wc(file_name):
out = subprocess.Popen(
["wc", "-l", file_name], stdout=subprocess.PIPE, stderr=subprocess.STDOUT
).communicate()[0]
return int(out.partition(b" ")[0])
def prepend_line(file_name, line):
with open(file_name, "r+") as f:
content = f.read()
f.seek(0, 0)
f.write(line.rstrip("\r\n") + "\n" + content)

# Skip if already done
if os.path.isfile(pcd_file):
print("pcd {} exists, skipped".format(pcd_file))
return

# which are non-integers.

错误如下:
