我有一個名為rra.py的腳本,它具有以下skelton結(jié)構(gòu)：

usn=""

usnl=[]

from bs4 import BeautifulSoup

import re

import asys

import glob

import os

import sys

import sys

def inputIndex():

#some processsing

def getval():

#some processing

def parsehtml():

#some processsing

def ret():

#some processing

def main():

inputIndex()

ret()

parsehtml()

getval()

print "watsuup"

asys.Compavg()

asys.compSub()

print "nearly done"

return 0

if __name__ == '__main__':

inputIndex()

main()

asys.Compavg()

asys.compSub()

我在上面的腳本rra.py中導入了另一個腳本asys.py,其中包含以下內(nèi)容.

import pandas as pd

import numpy as np

import matplotlib.pyplot as plt

from scipy import stats

import statsmodels.api as sm

from numpy.random import randn

import matplotlib as mpl

import seaborn as sns

sns.set_color_palette("deep", desat=.6)

mpl.rc("figure", figsize=(8, 4))

def Compavg():

data=Total()

markMax=[]

markAvg=[]

N = 5

ind = np.arange(N)

width = 0.35

fig = plt.figure()

ax = fig.add_subplot(111)

markMax.extend((data["Total"].max(),data["Total.1"].max(),data["Total.2"].max(),data["Total.3"].max(),data["Total.4"].max()))

markAvg.extend((data["Total"].mean(),data["Total.1"].mean(),data["Total.2"].mean(),data["Total.3"].mean(),data["Total.4"].mean()))

rects1 = ax.bar(ind, markMax, width, color='black')

rects2 = ax.bar(ind+width, markAvg, width, color='green')

ax.set_xlim(-width,len(ind)+width)

ax.set_ylim(0,120)

ax.set_ylabel('Marks')

ax.set_title('Max, Mean and Your Marks')

xTickMarks = ['Subject'+str(i) for i in range(1,6)]

ax.set_xticks(ind+width)

xtickNames = ax.set_xticklabels(xTickMarks)

plt.setp(xtickNames, rotation=10, fontsize=10)

ax.legend( (rects1[0], rects2[0]), ('Max', 'Mean') )

plt.show()

print "finished reading 1"

def compSub():

#max_data = np.r_[data["Total"]].max()

#bins = np.linspace(0, max_data, max_data + 1)

data=Total()

print data['Total']

plt.hist(data['Total'],linewidth=0, alpha=.7)

plt.hist(data['Total.1'],linewidth=0,alpha=.7)

plt.hist(data['Total.2'],linewidth=0,alpha=.7)

plt.hist(data['Total.3'],linewidth=0,alpha=.7)

plt.hist(data['Total.4'],linewidth=0,alpha=.7)

plt.title("Total marks Histogram")

plt.xlabel("Value")

plt.ylabel("Frequency")

plt.show()

print "finished reading 2"

def Total():

print "going to read"

data=pd.read_csv("output11cs.csv")

df3=data[['Total','Total.1','Total.2','Total.3','Total.4','Total.5','Total.6','Total.7']]

data["Main Total"]=df3.sum(axis=1)

data = data.dropna()

data.reset_index(drop=True)

return data

#compSub()

#Compavg()

當我通過使用python rra.py執(zhí)行virtualenv之外的rra.py(甚至在virtualenv內(nèi))時,它執(zhí)行完美并繪制asys.py中給出的圖形和直方圖.

然后我創(chuàng)建了一個’setup.py’文件來打包它,如下所示：

from ez_setup import use_setuptools

use_setuptools()

from setuptools import setup, find_packages

from setuptools.command.test import test as TestCommand

import vturra

import sys

class PyTest(TestCommand):

def finalize_options(self):

TestCommand.finalize_options(self)

self.test_args = []

self.test_suite = True

def run_tests(self):

import pytest

errcode = pytest.main(self.test_args)

sys.exit(errcode)

setup(name="vturra",

version=vturra.__version__,

license='Apache Software License',

tests_require=['pytest'],

install_requires=['matplotlib>=1.2.1',

'pandas',

'numpy',

'scipy',

'beautifulsoup',

'requests',

'patsy',

'seaborn==0.2.1',

'BeautifulSoup4'

],

cmdclass={'test': PyTest},

description="Downloads results from VTU website and analyzes the result",

long_description=open('README.md').read(),

package_data={'vturra': ['data/*.xml']},

include_package_data=True,

test_suite='vturra.test.test_vturra',

classifiers = [

],

extras_require={

},

entry_points={

"console_scripts": [

"vturra=vturra.rra:main"

#"pip%s=pip:main" % sys.version[:1],

#"pip%s=pip:main" % sys.version[:3],

],

}

)

我在virtualenv中使用python setup.py install安裝了軟件包,安裝完成后一切正常.現(xiàn)在,當我執(zhí)行包vturra時,我收到以下錯誤：

Traceback (most recent call last):

File "asys.py", line 65, in

KeyError: 0L

但是,如果我在main()中注釋掉函數(shù)調(diào)用asys.compSub(),它的工作沒有任何錯誤.

UPDATE

該函數(shù)作為virtualenv之外的獨立腳本執(zhí)行時效果很好,但在virtualenv中你會得到上述錯誤.

我相信這是virtualenv的一個問題呢？

最佳答案 終于解決了.這是最新版本的thepandas和matplotlib之間的問題.

與擁有0.13.0的virtualenv相比,Global System pandas版本為0.10.所以我在virtualenv降級到0.10.0.

現(xiàn)在它的工作完美.

基本上它與matplotlib和pandas的API不兼容> = 0.13. plt.hist與系列目前將面臨這個問題.

所以要么使用數(shù)據(jù)[‘Total.1’].hist()

或者傳入值plt.hist(data [‘Total.1’].values,….)

或?qū)andas降級到小于0.13的版本.
