UserWarning: Glyph 24046 (\N{CJK UNIFIED IDEOGRAPH-5DEE}) missing from current font. plt.savefig('score.png')报错怎么解决

这个报错提示是因为当前字体缺少了某个字符，可以尝试以下两种解决方法：

1. 更换字体

使用 plt.rcParams['font.sans-serif'] = ['SimHei'] 将字体更换为中文字体即可。例如：

import matplotlib.pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']
plt.plot([1, 2, 3])
plt.savefig('score.png')

2. 安装缺失的字体

可以通过安装缺失的字体来解决该问题。例如，在 Ubuntu 系统下，可以通过以下命令安装中文字体：

sudo apt-get install fonts-wqy-zenhei

安装完成后，重新运行代码即可。

这个警告是因为在你的代码中，使用了一些当前字体中没有包含的字符，导致这些字符无法正确显示。可以尝试更换字体或者忽略这个警告。如果你想忽略这个警告，可以在代码开头添加以下代码：

import warnings
warnings.filterwarnings("ignore", category=UserWarning)

这样就可以忽略这个警告了。但是，如果你想要正确显示这些字符，可以尝试更换字体。可以在代码中添加以下代码：

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

# 更换字体
myfont = fm.FontProperties(fname='C:\\Windows\\Fonts\\simsun.ttc')
plt.rcParams['font.family'] = ['sans-serif']
plt.rcParams['font.sans-serif'] = [myfont.get_name()]

# 画图
plt.plot(x, y)
plt.show()

这样就可以使用新的字体来显示图表中的字符了。

这是一些Matplotlib的警告信息。其中第一条警告表示，Matplotlib 3.6版本开始不再支持没有“required_interactive_framework”属性的FigureCanvases，这个属性用于指定绘图所需的交互式框架。如果你的代码中使用了这样的FigureCanvas，建议更新Matplotlib版本或修改代码以使用最新的FigureCanvas。

其他的警告则是指出当前字体中缺少一些中文字符，这可能会影响绘图结果的显示效果。可以通过更换字体或安装支持中文字符的字体来解决这个问题。

这些警告信息并不会影响代码的运行，只是提醒你可能需要注意一些绘图的细节问题。建议在代码中加入以下语句来禁止警告的输出：

import warnings

warnings.filterwarnings("ignore")
