查了下资料，应该是我强行转换格式（xlsx->csv）所引起的字符编码问题
这里稍微总结一下由字符编码问题引起的错误该如何解决办法呢，如下：

• 文件另存为csv
• 如果不是像我那样强转所导致的，就增加分隔符参数

? df = pd.read_csv(csv_path)
? df = pd.read_csv(csv_path, encoding=‘utf-8‘,sep = ‘\t‘)

或者增添这个参数

  df = pd.read_csv(csv_path, error_bad_lines=False) #报错

再或者增添这个参数

  df = pd.read_csv(csv_path, engine="python") #报错
