networkx - 为什么会有“预期任一字符串的元素”

Question

      import networkx as nx
      from bokeh.transform import linear_cmap
      from bokeh.io import show, output_notebook
      from bokeh.plotting import figure
      from bokeh.models import Circle, HoverTool, TapTool, BoxSelectTool
      from bokeh.models.graphs import from_networkx
      from bokeh.palettes import Spectral6
      output_notebook()
      G=nx.Graph(G_fb)
      plot = figure(x_range=(-1.1, 1.1), y_range=(-1.1, 1.1))
      plot.add_tools(HoverTool(tooltips=[("Name", "@name"), 
                               ("Club", "@club")]), 
                                TapTool(), 
                                BoxSelectTool())
      graph = from_networkx(G, nx.spring_layout, iterations=1000, scale=1, center=(0,0))
      graph.node_renderer.data_source.data['name'] = list(G.nodes())
      graph.node_renderer.glyph = Circle(size=10)
      graph.node_renderer.glyph = Circle(
      size=10, 
      fill_color=linear_cmap(degrees, palette=Spectral6,low=0, high=100, low_color='blue', high_color='red')

      plot.renderers.append(graph)
      show(plot)

它出现了一个错误说：

期望 String、Dict(Enum('expr', 'field', 'value', 'transform'), Either(String, Instance(Transform), Instance(Expression), Color)) 或 Color 的元素，得到 { '字段': [5, 6, 12, 7, 8, 6, 6, 9, 8, 4, 3, 5, 5, 7, 5, 7, 4, 4, 3, 6, 3, 5, 10 , 1, 7, 4, 8, 2, 9, 6, 5, 5, 9, 11, 11, 3, 9, 1, 10, 1, 6, 6, 5, 8, 7, 7, 4, 7 , 2, 1, 3, 1, 6, 3, 1, 1, 2, 2, 1, 2, 2, 1], '变换': LinearColorMapper(id='1194', ...)}

G_fb 的一部分： 11 1 15 1 16 1 41 1 43 1 48 1 18 2 20 2 27 2 28 2 29 2 37 2 42 2 55 2 11 3 43 3 45 3 62 3 9 4 15 4 60 4 52 5 10 6 14 6 57 6 58 6 10 7 14 7 18 7 55 7 57 7 58 7 20 8 28 8 31 8 41 8 55 8 21 9 29 9 38 9 46 9 60 9 14 10 18 10 33 10 42 10 58 10 3 43 11 48 11 52 12 34 13 18 14 33 14 42 14 55 14 58 14 17 15 25 15 34 15 35 15 38 15 39 15 41 15 44 15 51 15 53 15 19 16
