移动到服务器时Python脚本失败 - （Matplotlib版本控制）

Question

我有这个python脚本：

#!/usr/bin/python
import matplotlib.pyplot as plt
import numpy as np
import time
#from scipy.interpolate import spline

def myround(x, base=24*3600):
    return int(base * round(float(x)/base))

def processFile(filename):
    file = open(filename)
    lastrawline="Hello"
    rawline = file.readline()
    #the array we have is going to be horizonal when we need vertical. So we have to deal with that. 
    dayold=[]
    weekold=[]
    threedayold=[]
    seconds=[]
    now=[]
    count=0
    for rawline in file:
        splitline=rawline.split()
        dayold.insert(0,splitline[4])
        threedayold.insert(0,splitline[5])
        weekold.insert(0,splitline[3])
        seconds.insert(0,splitline[2])
        now.insert(0,splitline[0])
            count=count+1   
    return (seconds,now,dayold,threedayold,weekold)

def graph(seconds,now, dayold, threedayold,weekold):
    dis=4*24*60*60
    x = np.array(seconds[-dis:])

    #x = np.arange(len(seconds))
    ynow = np.array(now)
    yday = np.array(dayold)
    y3day = np.array(threedayold)
    yweek = np.array(weekold)
    # y2 should go on top, so shift them up
    plt.plot(x,ynow, 'white')
    plt.plot(x,yday)
    plt.plot(x,y3day,'purple')
    plt.plot(x,yweek)
    plt.fill_between(x,ynow,yday,color='lightblue')
    plt.fill_between(x,yday,y3day,color='green')
    plt.fill_between(x,y3day,yweek,color='purple')
    plt.fill_between(x,yweek,[0] *len(seconds),color='red')
    currenttime=int(seconds[0])
    print currenttime
    lastweek=myround(currenttime-7*24*3600)
    print lastweek
    plt.xlim(lastweek, currenttime)
    ticks=np.arange(lastweek,currenttime,24*3600)
    labels=[time.strftime("%a", time.gmtime(x)) for x in ticks]
    plt.xticks(ticks,labels)
    plt.grid()
#   plt.show()
    plt.savefig('stress.png')

#processFile("/home/pgrads/joseph/Dropbox/emailAnalysis/resultsOldest.txt")
a=processFile("results.txt")
graph(a[0],a[1],a[2],a[3],a[4])

这会产生这个图表，这很棒。

至少在我的本地机器上。

当我将其上传到服务器时，它会抛出以下错误。

Traceback (most recent call last):
  File "./plotNextActionData.py", line 63, in <module>
    graph(a[0],a[1],a[2],a[3],a[4])
  File "./plotNextActionData.py", line 45, in graph
    plt.fill_between(x,ynow,yday,color='lightblue')
  File "/home/joereddington/env/matplotlib-1.4.0-py2.6-linux-x86_64.egg/matplotlib/pyplot.py", line 2820, in fill_between
    interpolate=interpolate, **kwargs)
  File "/home/joereddington/env/matplotlib-1.4.0-py2.6-linux-x86_64.egg/matplotlib/axes/_axes.py", line 4316, in fill_between
    x = ma.masked_invalid(self.convert_xunits(x))
  File "/home/joereddington/env/numpy-1.8.2-py2.6-linux-x86_64.egg/numpy/ma/core.py", line 2239, in masked_invalid
    condition = ~(np.isfinite(a))
TypeError: Not implemented for this type

注释掉fill_between调用可以很好地生成图形

这不是我想要的那个。知道发生了什么事吗？ MatplotLib显然正在工作，只是这些电话很难......

编辑 - 版本。

家用机器：

josephs-mbp-3$more scrap.py 
import numpy as np
import time
import matplotlib.pyplot 
#from scipy.interpolate import spline

print np.__version__
print matplotlib.__version__
josephs-mbp-3$python scrap.py 
1.6.2
1.1.1
josephs-mbp-3$

服务器：

 blout$more scrap.py 
import numpy as np
import time
import matplotlib.pyplot 
#from scipy.interpolate import spline

print np.__version__
print matplotlib.__version__
blout$python scrap.py 
1.8.2
1.4.0

可能是MatplotLib库的版本吗？也许检查您在本地和服务器上安装的版本。
