问题描述

在做YoloV5剪枝的时候，遇到如下问题;

   return load(stream, SafeLoader)
  File "D:\Users\wh109\anaconda3\lib\site-packages\yaml\__init__.py", line 79, in load
    loader = Loader(stream)
  File "D:\Users\wh109\anaconda3\lib\site-packages\yaml\loader.py", line 34, in __init__
    Reader.__init__(self, stream)
  File "D:\Users\wh109\anaconda3\lib\site-packages\yaml\reader.py", line 85, in __init__
    self.determine_encoding()
  File "D:\Users\wh109\anaconda3\lib\site-packages\yaml\reader.py", line 124, in determine_encoding
    self.update_raw()
  File "D:\Users\wh109\anaconda3\lib\site-packages\yaml\reader.py", line 178, in update_raw
    data = self.stream.read(size)
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 198: illegal multibyte sequence

读取data的yaml文件遇到了无法解析的字符。

原因分析

新版本的YoloV5，在yaml文件里有个小火箭的图标

# YOLOv5 🚀 by Ultralytics, GPL-3.0 license

把这个删除掉就可以了
