Matplotlib 动画不接受圆形补丁作为farg

Question

import math

import matplotlib

import matplotlib.pyplot as plt

import matplotlib.patches as patches

from matplotlib.patches import Circle

from matplotlib import animation

from utils import rgb2hex

from tg import small_tg

matplotlib.rcParams["figure.figsize"]=(10, 5)

matplotlib.rcParams['toolbar'] = 'None'

fig, ax = plt.subplots()

ax.axis("equal")

ax.set_xlim(-10, 10)

ax.set_ylim(-5, 5)

ax.axis("off")

state_nodes = []

for state in small_tg["states"]:

    center = small_tg["states"][state]["graphic_properties"]["position"]

    state_nodes.append(Circle(center, 0.2, color = rgb2hex(255, 255, 255)))

def animate(i, state):

    print("&", i ,state)

    y = math.ceil((abs(i-100))*2.55)

    print(i, y, (abs(i-100))*2.55)

    state.set_color = rgb2hex(y,y,y)

    ax.add_artist(state)

    return state,

for state in state_nodes:

    print(state)

    animation.FuncAnimation(fig, animate, fargs = (state,), frames=201, interval=1, blit=True, repeat = False)

plt.show()

for 循环内的打印语句显示状态，但是 animate 函数内的打印语句没有显示任何内容，这意味着该函数没有被调用。我找不到任何逻辑错误。请帮忙。
