Python Kreisdiagramm Traceback

Question

Ich versuche, ein Tortendiagramm in Python zu machen, und ich bekomme diese Traceback. Hier ist mein Code

#!/usr/bin/python 

import sys 
import re 
import matplotlib.pyplot as plt 

file1 = open(sys.argv[1]) 
file2 = open(sys.argv[2]) 
file3 = open(sys.argv[3]) 

all = [] 

count_1 = 0 
count_2 = 0 
count_3 = 0 

for line in file1: 
    line = line.strip() 
    if line.startswith(">"): 
     count_1 += 1 

all.append(count_1) 

for line in file2: 
     line = line.strip() 
     if line.startswith(">"): 
       if re.search("CAGE_PLUS", line): 
      count_2 += 1 

all.append(count_2) 

for line in file3: 
     line = line.strip() 
     if line.startswith(">"): 
     if re.search("known", line): 
        count_3 += 1 


all.append(count_3) 


labels = ["All lincRNA", "CAGE lincRNA", "Known lincRNA"] 
sizes = all 
colors = ['yellowgreen', 'mediumpurple', 'lightskyblue'] 

plt.pie(sizes,    # data 
     labels=labels,  # slice labels 
     colors=colors,  # array of colours 
     autopct='%1.1f%%' # print the values inside the wedges 
     ) 
plt.axis('equal') 

plt.savefig('lincRNA_piechart') 

Dies ist, wie ich es bin mit

python /evolinc_docker/lincRNA_fig.py All.lincRNAs.fa lincRNAs.with.CAGE.support.annotated.fa lincRNAs.overlapping.known.lincs.fa 

Und die Zurückverfolgungs ich bin ist immer

Traceback (most recent call last):

    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) 
_tkinter.TclError: no display name and no $DISPLAY environment variable 

Answer 1

Ich lief das Programm mit allen Liste vereinfacht.

import matplotlib.pyplot as plt 
labels = ["All lincRNA", "CAGE lincRNA", "Known lincRNA"] 
sizes = [10, 20, 30] # my arbitrary list just for testing 
colors = ['yellowgreen', 'mediumpurple', 'lightskyblue'] 
plt.pie(sizes, labels=labels,colors=colors, autopct='%1.1f%%') 
plt.axis('equal') 
plt.show() 

Und ich könnte die folgende Handlung bekommen. Also ich denke, Ihr Python-Programm ist in Ordnung. Aber ich habe DISPLAY env Variable überprüft und es ist

Vielleicht möchten Sie Ihr DISPLAY überprüfen und richtig einstellen.
