pycharm中names[c] if hide_conf else f'{count}\n{conf:.2f}'\n无法分行只显示?怎么改

在PyCharm中,使用`\n`来换行有时可能无法正常工作,这可能是因为PyCharm的默认设置不会将`\n`解释为换行符。你可以尝试在字符串前面加上字母`r`,将其转换为raw string,这样`\n`就会被正确解释为换行符。例如: ``` names[c] if hide_conf else rf'{count}\n{conf:.2f}' ``` 这样{count}和{conf:.2f}就会在输出结果中分行显示。

还是没有让{count}和{conf:.2f}输出分行

如果在PyCharm中使用raw string和`\n`仍然无法让{count}和{conf:.2f}输出分行,你可以尝试使用`os.linesep`代替`\n`。`os.linesep`是Python中与平台相关的换行符,可以根据当前操作系统的不同自动选择使用`\n`或`\r\n`。例如: ``` import os names[c] if hide_conf else f'{count}{os.linesep}{conf:.2f}' ``` 这样{count}和{conf:.2f}就会在输出结果中分行显示。

pycharm中没有 if __name__ == '__main__': unittest.main()代码执行报错问题

如果在 PyCharm 中执行 unittest 测试时遇到了 `if __name__ == '__main__': unittest.main()` 报错的问题,可能是因为 PyCharm 中的配置问题。解决方法如下: 1. 确认测试代码中包含了 `if __name__ == '__main__': unittest.main()`,并且没有语法错误。 2. 在 PyCharm 中,打开运行配置(Run Configuration)对话框。 3. 在对话框中,选择要运行的测试文件或测试目录,并且选择 Python 解释器。 4. 在运行选项卡下,找到 Working directory 选项,选择项目根目录或测试文件所在目录。 5. 点击 OK 保存配置,然后重新运行测试。 如果以上方法无法解决问题,可以尝试升级 PyCharm 版本或者重新安装 Python 解释器。

解释minorization-maximization (MM) algorithm,并给出matlab代码编写的例子

Minorization-maximization (MM) algorithm是一种常用的优化算法,用于求解非凸问题或含有约束的优化问题。该算法的基本思想是通过构造一个凸下界函数来逼近原问题,然后通过求解凸下界函数的最优解来逼近原问题的最优解。具体步骤如下: 1. 初始化参数 $\theta_0$,设 $k=0$; 2. 构造一个凸下界函数 $Q(\theta|\theta_k)$,使其满足 $Q(\theta_k|\theta_k)=f(\theta_k)$; 3. 求解 $Q(\theta|\theta_k)$ 的最优值 $\theta_{k+1}=\arg\min_\theta Q(
