Question

我正在尝试导入tsv文件。其中一条线很糟糕，我不知道哪一条。我想要大熊猫忽略那条线。这不起作用：

bob_date_parser2 = lambda x: datetime.datetime.strptime(x, "%m/%d/%Y")  #"3/7/2013"
df = pd.read_csv(fname, sep="\t", parse_dates=['country_release'], date_parser=bob_date_parser2, encoding='utf8',
                 warn_bad_lines=False, error_bad_lines=False)

我知道我的文件处理是正确的，因为我只能head第一行并导入而没有任何问题。但是，当我尝试使用

时，我的整个文件read_csv失败了

我在熊猫上13.1

Pandas warn_bad_lines = False，error_bad_lines = False仍在尝试解析坏线
