windows yolov5 代码运行train.py时报错：

  File "D:\Anaconda\envs\torch2\lib\site-packages\yaml\loader.py", line 34, in __init__
    Reader.__init__(self, stream)
  File "D:\Anaconda\envs\torch2\lib\site-packages\yaml\reader.py", line 85, in __init__
    self.determine_encoding()
  File "D:\Anaconda\envs\torch2\lib\site-packages\yaml\reader.py", line 124, in determine_encoding
    self.update_raw()
  File "D:\Anaconda\envs\torch2\lib\site-packages\yaml\reader.py", line 178, in update_raw
    data = self.stream.read(size)
UnicodeDecodeError: 'gbk' codec can't decode byte 0xaf in position 238: illegal multibyte sequence

看起来像是编码解码错误；

前面都是系统的代码，最后追述yolov5自定义的代码到这句：

data_dict = yaml.safe_load(f)  # data dict

网上搜索后，根据参考链接1修改为：

with open(data, "r", encoding='UTF-8') as f:

就好了，但是后面又有其它错误，慢慢改之吧；
