anaconda+tensorflow-gpu+matplotlib matplotlib无法绘图

Question

import matplotlib

matplotlib.use('TkAgg')
import matplotlib.pyplot as plt

plt.plot([1,2,3,4])

plt.ylabel('some numbers')

plt.show()

当运行上述代码时，报错

ImportError: Cannot load backend 'TkAgg' which requires the 'tk' interactive framework, as 'headless' is currently running

matplotlib的版本号为3.2，使用matplotlib.get_backend()
时返回为'agg'
将后端改为'TkAgg'时出现上述报错
但是使用conda list命令查询安装包时发现其实已经安装了tk
