Python 属性错误：'；模块'；对象没有属性'；打开'；

我正在尝试使用以下代码在Linux中打开压缩为.lzma文件的.csv文件：

import lzma
import pandas as pd

myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

with lzma.open(myfile,'rt') as f:
   pair_info=pd.read_csv(f,engine='c',header=0,index_col=0)

其中myfile是Linux中存在的路径

但是我得到了一个错误：

with lzma.open(stock,'rt') as f:
AttributeError: 'module' object has no attribute 'open'

    with lzma.LZMAFile(compressed,'r') as uncompressed:
TypeError: coercing to Unicode: need string or buffer, file found

open_cmd=open if compression is None else __import__(compression).open
AttributeError: 'module' object has no attribute 'open'

我尝试添加以下内容：

import lzma
import pandas as pd

    myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

    with open(myfile) as compressed:
         with lzma.LZMAFile(compressed,'r') as uncompressed:
             line in uncompressed:
             print(line)  

但我得到了一个错误：

with lzma.open(stock,'rt') as f:
AttributeError: 'module' object has no attribute 'open'

    with lzma.LZMAFile(compressed,'r') as uncompressed:
TypeError: coercing to Unicode: need string or buffer, file found

open_cmd=open if compression is None else __import__(compression).open
AttributeError: 'module' object has no attribute 'open'

我也尝试过：

import pandas as pd
import lzma
import pickle

myfile= '/home/stacey/work/roll_158_oe_2018-03-02/BBG.XTKS.8219.S/inst.BBG.XTKS.8219.S.csv.lzma'

myoutput = pickle_load(myfile,'lzma')
print(myoutput )

def pickle_load(filePath,compression=None):
    open_cmd=open if compression is None else __import__(compression).open
    with open_cmd(filePath,'r') as f:
        output=pickle.load(f)
    return output

但我还是犯了一个错误：

with lzma.open(stock,'rt') as f:
AttributeError: 'module' object has no attribute 'open'

    with lzma.LZMAFile(compressed,'r') as uncompressed:
TypeError: coercing to Unicode: need string or buffer, file found

open_cmd=open if compression is None else __import__(compression).open
AttributeError: 'module' object has no attribute 'open'

当我在cmd行上运行python-v时，我得到了以下输出：

>>> import lzma

我做错了什么？我怎样才能让它工作？我环顾四周，但看不到任何其他解决方案。

显然，您需要从

lzma

模块调用一个类来打开文件：

import lzma#python 3，试试python 2中的lzmaffi
将open（'one-csv-file.xz'）压缩为：
lzma.LZMAFile（压缩）为未压缩：
对于未压缩的行：
用（线）填充

摘自

Python2.7.x和Python3.3+之间的lzma模块存在一些差异

Python2.7.x没有

lzma.open

和

lzma.LZMAFile

不接受类似文件的对象。这里有一个函数，用于以独立于Python版本的方式打开

lzma

文件

def open_lzma_file(f, *args, **kwargs):
    import os
    try:
        import lzma
    except ImportError:
        raise NotImplementedError('''This version of python doesn't have "lzma" module''')
    if hasattr(lzma, 'open'):
        # Python 3.3+
        # lzma.open supports 'str', 'bytes' and file-like object
        return lzma.open(f, *args, **kwargs)
    # Python 2.7.x
    # This version has LZMAFile 
    # LZMAFile doesn't take-file like object in Python 2.7
    if not isinstance(f, basestring):
        # probably a file like object
        if hasattr(f, 'name') and os.path.exists(f.name):
            f = f.name
        else:
            raise TypeError('Expected `str`, `bytes`, `unicode` or file-like object with valid `name` attribute pointing to a valid path')
    return lzma.LZMAFile(f, *args, **kwargs)

用法
只需传递一个

str

、

bytes

或类似文件的对象

with open_lzma_file(myfile,'rt') as f:
   pair_info=pd.read_csv(f,engine='c',header=0,index_col=0)

您是否调用了您的文件

lzma.py

？如果是这样，请将其重命名为.Hi@roganjosh，没有名为lzma.py的文件。您是从命令行还是IDE工作的？第一个代码段应适用于python3.3或更高版本。尝试从命令行调用它，将其作为方法列出谢谢@Luca Bezerra。我试图实现yur Solution（请参见对问题的编辑），但我得到了一个不同的错误：lzma.LZMAFile（已压缩，'r'）为未压缩：TypeError：强制使用Unicode：需要字符串或缓冲区，找到文件您能看一下吗please@Stacey1.您使用的是什么版本的python？2.您知道导入的

lzma

是否正确吗？尝试

python-v

，然后

importlzma

，并检查路径是否符合您的期望。您的路径中可能安装了另一个lzma包或版本。@LucaBezerra谢谢，我正在运行Python 2.7.12。我可以导入lzma，但不知道如何判断我的版本（lzma.\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。这有帮助吗？@Stacey你用什么命令来运行脚本？当您运行

Python

时，您粘贴的更新输出似乎使用python2作为默认版本。您是否在某种虚拟环境中运行脚本？如果没有，您可以尝试运行

python3.py

？
