我导入functools后,我从解释器收到这样的消息:

回溯(最近一次调用最后一次):文件"C:/Users/Admin/Documents/Python/decorator.py",第1行,在导入functools文件"C:\ Python3\lib\functools.py",第22行,in从类型导入MappingProxyType ImportError:无法导入名称'MappingProxyType'

import functools


def trace(func):
    def inner(*args, **kwargs):
        print(func.__name__, args, kwargs)
        return func(*args, **kwargs)
    functools.update_wrapper(inner, func)
    return inner


@trace
def foo(x):
    return x


foo(42)

使用PyCharm作为IDE,使用CPython作为解释器

我正在使用 pythonanywere.com 来部署我的 Django 应用程序。所以我在那个虚拟环境中安装了一些机器学习库。

您可以在下面看到我在故事板中的项目层次结构。问题是内容大小缩小并等于滚动视图高度。我想这是因为故事板迫使我明确指定我不应该做的表格视图的高度。但是我应该如何指示内容视图的动态高度？

约束列表：

我知道有几个主题在考虑同一个问题，但是那里给出的方法实际上并没有帮助。

我的项目结构如下所示：

• CMakeLists.txt
• 部门
  • 格卢
  • GLFW
• 包括
• 源代码
  • ...
  • 图形
    • ...
    • CMakeLists.txt

两个值得关注的 CMakeLists.txt 文件：
