KeyError:运行打包的代码时为0L [英] KeyError: 0L when running packaged code

问题描述

我有一个名为rra.py的脚本，该脚本具有以下skelton结构:

I have script called rra.py that has the following skelton structure:

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()

，我还有另一个脚本asys.py，我已在上述脚本rra.py中导入了该脚本，内容如下.

and I have another script asys.py which I have imported in the above script rra.py which has the following content.

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()

当我使用python rra.py在virtualenv外部(甚至在virtualenv内部)执行rra.py时，它会完美执行并绘制asys.py中给出的图和直方图.

When I execute rra.py outside virtualenv(even inside virtualenv) by using python rra.py it executes perfectly and plots the graph and histogram as given in asys.py.

然后我创建了一个"setup.py"文件进行打包，如下所示:

Then I created a 'setup.py' file to package it which is given below:

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__,

    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(),
    author="Muhammed Thaha",
    author_email='[e-mail]',
    download_url='https://github.com/stormvirux/vturra',
    packages=find_packages(exclude='tests'),
    package_data={'vturra': ['data/*.xml']},
    include_package_data=True,
    platforms='any',
    test_suite='vturra.test.test_vturra',
    classifiers = [
        'Programming Language :: Python',
        'Development Status :: 1 - Beta',
        'Natural Language :: English',
        'Environment :: Web Environment',
        'Intended Audience :: Developers',
        'License :: OSI Approved :: Apache Software License',
        'Operating System :: OS Independent',
        'Topic :: Internet :: WWW/HTTP :: Dynamic Content',
        ],
    extras_require={
        'testing': ['pytest'],
    },
    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安装了软件包，安装一切正常.现在，当我执行包vturra时，出现以下错误:

I installed the package using python setup.py install in virtualenv and everything went fine with installation. Now when I execute the package vturra I get the following error:

Traceback (most recent call last):
  File "asys.py", line 65, in <module>

KeyError: 0L

但是，如果我注释掉main()中的函数调用asys.compSub()，它将正常工作.

But if I comment out the function call asys.compSub() in main() it works without any error.

更新 当在virtualenv外部作为独立脚本执行时，该函数完美工作，但是在virtualenv内部，您会遇到上述错误. 我相信这是virtualenv的问题吗?

UPDATE The function works perfectly when executed as a standalone script outside virtualenv but inside virtualenv you get the above error. I beleive it is an issue with virtualenv then?

推荐答案

最终解决了它.这是最新版本的pandas和matplotlib之间的问题. 与具有0.13.0的virtualenv相比，Global System pandas版本为0.10.因此，我在virtualenv中降级为0.10.0.

Finally solved it. It was an issue between latest version ofpandas and matplotlib. Global System pandas version was 0.10 compared to virtualenv that had 0.13.0. So I downgraded to 0.10.0in virtualenv.

现在可以正常工作了.

基本上与matplotlib和pandas> = 0.13的API不兼容. plt.hist系列目前会遇到此问题.

Basically its an API incompatibility with matplotlib and pandas >= 0.13. plt.hist with a Series currently will face this problem.

所以要么使用data['Total.1'].hist()

或传入值plt.hist(data['Total.1'].values,....)

或将熊猫降级到小于0.13的版本.

or downgrade pandas to a version lesser than 0.13.
