Python Matplotlib-单空间字体和格式错误警告

运行中的代码没有任何更改，但现在我遇到了这个错误，我不知道该怎么办：

/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1224: UserWarning: findfont: Font family ['monospace'] not found. Falling back to Bitstream Vera Sans
  (prop.get_family(), self.defaultFamily[fontext]))
/usr/lib/python2.7/site-packages/IPython/core/formatters.py:239: FormatterWarning: Exception in image/png formatter: Locator attempting to generate 20001 ticks from 0.0 to 100.0: exceeds Locator.MAXTICKS
  FormatterWarning,

这句话对我起了作用

sudo pacman -S dina-font

这里是网页的字体

如果您不在Linux上，则必须下载该文件并将其存储在适当的文件夹中。这些是：

#  OS Font paths
MSFolders = \
    r'Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders'

MSFontDirectories   = [
    r'SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts',
    r'SOFTWARE\Microsoft\Windows\CurrentVersion\Fonts']

X11FontDirectories  = [
    # an old standard installation point
    "/usr/X11R6/lib/X11/fonts/TTF/",
    "/usr/X11/lib/X11/fonts",
    # here is the new standard location for fonts
    "/usr/share/fonts/",
    # documented as a good place to install new fonts
    "/usr/local/share/fonts/",
    # common application, not really useful
    "/usr/lib/openoffice/share/fonts/truetype/",
    ]

OSXFontDirectories = [
    "/Library/Fonts/",
    "/Network/Library/Fonts/",
    "/System/Library/Fonts/",
    # fonts installed via MacPorts
    "/opt/local/share/fonts"
    ""
]

monospace字体是否仍在安装？另外，

FormatterWarning

非常直截了当地告诉您出了什么问题。我认为这是在转移注意力。完全相同的代码工作正常，没有任何警告。顺便说一句，我该如何解决单空格字体的问题？我们不能帮助你的代码。
