C:\Program Files\JetBrains\PyCharm 2021.3\plugins\python\helpers\pycharm_matplotlib_backend\backend_interagg.py:68: UserWarning: Glyph 21697 (\N{CJK UNIFIED IDEOGRAPH-54C1}) missing from current font. FigureCanvasAgg.draw(self怎么解决

这个警告提示了一个问题：在当前环境中找不到“\N{CJK UNIFIED IDEOGRAPH-54C1}”这个字符的字形信息，也就是“产品”这个汉字的字形信息。因此，当 matplotlib 绘制图形时，无法正确显示该字符。

要解决这个问题，你可以通过以下步骤进行操作：

1. 安装中文字体库，例如 SimHei 字体库。

2. 在代码中进行如下设置：

   import matplotlib
   matplotlib.rcParams['font.family'] = 'sans-serif'
   matplotlib.rcParams['font.sans-serif'] = ['SimHei']

这样，就可以在 matplotlib 中使用 SimHei 字体来显示中文字符。

3. 如果你仍然收到警告，可以尝试重新生成 matplotlib 的字体缓存：

   import matplotlib.font_manager as fm
   fm._rebuild()

这会重新生成 matplotlib 的字体缓存，从而确保 matplotlib 能够正确地加载所有字体。

通过以上操作，你应该可以解决该警告问题。

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")

解释下这段报错内容C:\Program Files\JetBrains\PyCharm 2021.3.1\plugins\python\helpers\pycharm\_jb_pytest_runner.py:8: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html from pkg_resources import

这段报错内容是在运行 PyCharm 的 pytest_runner.py 文件时出现的。报错信息指出，使用 pkg_resources 模块的方式已被标记为过时（DeprecationWarning）并且不再推荐使用。pkg_resources 是一个用于处理 Python 包和资源的工具，但现在官方推荐使用 setuptools 库来代替它。

建议你查看给出的链接，了解如何使用 setuptools 来替代 pkg_resources，以解决这个问题。
