matplotlib安装好了但是进行导入的时候就报错如下图：

经过搜集资料通过如下方法解决： 

找到路径中的位置C:\Ananconda\envs\tf_1_5\Lib\site-packages\pyparsing（因为我是在tensorflow中跑的代码，相应的python环境也在这里面，你只需要找到安装python的位置，就可以找到对应的__init__.py文件）

 打开__init__.py文件并将下面的代码进行修改

class version_info(NamedTuple):
    major: int
    minor: int
    micro: int
    releaselevel: str
    serial: int

    @property
    def __version__(self):
        return "{}.{}.{}".format(self.major, self.minor, self.micro) + (
            "{}{}{}".format(
                "r" if self.releaselevel[0] == "c" else "",
                self.releaselevel[0],
                self.serial,
            ),
            "",
        )[self.releaselevel == "final"]

    def __str__(self):
        return "{} {} / {}".format(__name__, self.__version__, __version_time__)

    def __repr__(self):
        return "{}.{}({})".format(
            __name__,
            type(self).__name__,
            ", ".join("{}={!r}".format(*nv) for nv in zip(self._fields, self)),
        )

修改后的代码

class version_info():
  def __init__(self,major:int,minor:int,micro:int,releaselevel:str,serial:int):   
      self.major = major
      self.minor = minor
      self.micro = micro
      self.releaselevel = releaselevel
      self.serial = serial
  @property
  def __version__(self):
      return "{}.{}.{}".format(self.major, self.minor, self.micro) + (
          "{}{}{}".format(
              "r" if self.releaselevel[0] == "c" else "",
              self.releaselevel[0],
              self.serial,
          ),
          "",
      )[self.releaselevel == "final"]
  def __str__(self):
      return "{} {} / {}".format(__name__, self.__version__, __version_time__)
  def __repr__(self):
      return "{}.{}({})".format(
          __name__,
          type(self).__name__,
          ", ".join("{}={!r}".format(*nv) for nv in zip(self._fields, self)),
      )
