Question

我正在尝试训练我的模型，并且我有早先生成的csv文件和一个gz文件。我收到此错误，如下所述，不确定是什么错误。

Traceback (most recent call last):
  File "Model.py", line 87, in <module>
    data = pd.concat([pd.read_csv(log)])

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

我的代码：

for foo in range(0,1):
    # Read dataframe
    #data = pd.concat([pd.read_csv(log.replace('0',str(idx),1)) for idx in range(5)])
    log = path + 'train_features/log_.csv'

    test_log = path + 'test_features/log_features.gz'
    data = pd.concat([pd.read_csv(log)])

尝试：

data = pd.read_csv(log, encoding = "utf-8")

尽管我不明白为什么您需要for循环或pd.concat

如果您不知道编码类型，请尝试：此：

import chardet

with open(log, 'rb') as f:
    result = chardet.detect(f.read())  # or readline if the file is large


data = pd.read_csv(log, encoding=result['encoding'])

串联时出现Unicode DecodeError
