UnicodeDecodeError: 'gbk' codec can't decode byte 0xa1 in position 41: illegal multibyte sequence
问题文件：
PaddleDetection\ppdet\core\workspace.py
cfg = AttrDict()
with open(file_path) as f:
问题原因：
文件open时没有指定 encoding='UTF-8'，使用GBK打开yml
修改如下：
cfg = AttrDict() with open(file_path, encoding='UTF-8') as f:
