python + igrph。類型錯誤：繪圖不可

我想使用Python筆記本，IGRAPH包繪製的圖片，例如代碼是在這裏（我認爲這是正確的）python + igrph。類型錯誤：繪圖不可

!pip install cairocffi 
import cairocffi as cairo 

corlor = [] 
for i in g.vs['name']: 
    if set([i]) < set(degree_15): 
     corlor.append('red') 
    elif set([i]) < set(degree_30): 
     corlor.append('rgba(255,0,0,0.5)') 
    elif set([i]) < set(degree_60): 
     corlor.append('orange') 
    else: 
     corlor.append('yellow') 
ig.plot(g, 
     #'C:\Users\Vincent Du\Desktop\degree_plot.jpg', 
     layout=geometry_layout, 
     vertex_label=g.vs['name'], 
     scale=1.0, 
     vertex_color=corlor, 
     vertex_frame_width=0.5, 
     edge_width=0.05, 
     vertex_label_size=ig.rescale(g.degree(),out_range=(1,12)), 
     vertex_size=ig.rescale(g.degree(),out_range=(5,25)), 
     bbox=(1200,800), 
     margin = 10, 
     )

而且還是一個錯誤。我不知道如何解決這個問題，謝謝！

我想我已經安裝了開羅，但它仍然無法正常工作

我不知道究竟是什麼數據類型的ig.plot（）有，但作爲「類型錯誤」表明，一些你的參數有錯誤的數據類型。也似乎你使用的是Python3，它應該是pip3而不是pip。希望這可以幫助你。
