我遇到了我的csv输入文件故障的整体阅读问题,可以通过在我的read_csv函数中添加“ error_bad_lines = False” 来解决这些问题。
但是我需要报告创建问题的许多文件,我以为我需要捕获该异常。我通过使用
进行了尝试except pd.parser.CParserError
和
except ExceptionSubclass as exceptionsubclass:
通过Internet搜索后,在两种情况下我都无法捕获此异常,如果您有任何举报所有故障文件的想法,请告诉我。
我遇到错误:
Traceback (most recent call last):

答案 0 :(得分:0)
尝试使用except pd.errors.ParserError
代替except pd.parser.CParserError
。
这是大熊猫饲养的exception。
