查了下資料，應該是我強行轉換格式（xlsx->csv）所引起的字符編碼問題
這里稍微總結一下由字符編碼問題引起的錯誤該如何解決辦法呢，如下：
- 文件另存為csv
- 如果不是像我那樣強轉所導致的，就增加分隔符參數
df = pd.read_csv(csv_path)
df = pd.read_csv(csv_path, encoding='utf-8',sep = '\t')
或者增添這個參數
df = pd.read_csv(csv_path, error_bad_lines=False) #報錯
再或者增添這個參數
df = pd.read_csv(csv_path, engine="python") #報錯
