Question

我一般都是python / scripting的新手。需要有关如何解决问题的指导。我有以下python代码，可以在我的Mac上工作，但不是当我切换到Windows时。

create_data_frame.py

#!/usr/bin/env python
from argparse import ArgumentParser
from data_frame import DataFrame
from display_statistics import DisplayStatistics
from pprint import pprint


def main():

    # cli args
    parser = ArgumentParser()

    parser.add_argument(
        '-v', '--verbose',
        help='More verbose output',
        action='store_true',
        default=False,
    )

    """
    parser.add_argument('-t', '--datatype',
        help = 'what is the data type: csv, excel, webpage?',
        required=True )
    """

    parser.add_argument(
        '-r', '--rootpath',
        help='root path',
        required=True
    )

    parser.add_argument(
        '-p', '--pattern',
        help='pattern to look for',
        required=True,
    )

    args = parser.parse_args()

    df1 = DataFrame(
        root_path=args.rootpath,
        pattern=args.pattern,
    )

    df2 = DisplayStatistics(root_path=args.rootpath,
                            pattern=args.pattern,
    )
    print 'From data_frame'

    df1.data_frame()
    df1.summary_stats()


    print 'From display_statistics'
    #df2.data_frame()
    #df2.get_dict()
    #print df2.summary_stats()
    #print df2.box_plot()
    #print df2.cross_tab()






if __name__ == '__main__':
    main()

data_frame.py

# !/usr/bin/env python

from os import path, walk
from fnmatch import filter
import pandas as pd


class DataFrame(object):
    def __init__(self, root_path, pattern):
        self.root_path = root_path
        self.pattern = pattern
        self.rf_list = []  # create  empty list to store ReaderAnalysis.csv locations
        self.all_readerfiles = []
        self.frame = pd.DataFrame()


    def get_dict(self):
        return {
            'root_path': self.root_path,
            'pattern': self.pattern,
            'rf_list': self.rf_list,
            'all_readerfiles': self.all_readerfiles,
            'frame': self.frame
        }

    def data_frame(self):
        for root, dirs, files in walk(self.root_path):
            for filename in filter(files, self.pattern):
                self.rf_list.append(path.join(root, filename))

        for readerfiles in self.rf_list:
            df = pd.read_csv(readerfiles)
            df["Sample_IDs"] = ['Control 1','Control 2','Control 3','Control 1','Control 2','Control 3']
            df['RunID'] = readerfiles[readerfiles.find("_RunID") + 1:readerfiles.find("/ReaderFiles")]
            df['Instrument'] = readerfiles[readerfiles.find("Data/") + 5:readerfiles.find("_")]
            self.all_readerfiles.append(df)
        self.frame = pd.concat(self.all_readerfiles)

    def summary_stats(self):
        class_type = type(self.frame)
        dim = self.frame.shape
        first_6 = self.frame.head(6)
        last_6 = self.frame.tail(6)
        describe = self.frame.describe()
        return [class_type, dim,describe]

我收到以下错误：

Traceback (most recent call last):
  File "create_data_frame.py", line 67, in <module>
    main()
  File "create_data_frame.py", line 50, in main
    df1.data_frame()
  File "D:\ControlTracking\create_data_frame\data_frame.py", line 37, in data_frame
    self.frame = pd.concat(self.all_readerfiles)
  File "C:\Python27\lib\site-packages\pandas\core\reshape\concat.py", line 206, in concat
    copy=copy)
  File "C:\Python27\lib\site-packages\pandas\core\reshape\concat.py", line 239, in __init__
    raise ValueError('No objects to concatenate')
ValueError: No objects to concatenate

我在我的Mac上运行相同的代码并且工作正常。我有什么明显的差异吗？我可能在设置环境时犯了错误，但我该如何检查。

Pycharm Mac与Windows 10
