解决问题了的话求看官老爷们给个👍哈 谢谢支持QAQ
日常总结我踩过的坑 今天是cnocr的安装 首先第一行代码 pip安装cnocr（一个ocr工具第三方库 ）
pip install cnocr -i https://pypi.tuna.tsinghua.edu.cn/simple/
报错信息在文末 需要翻老底的可以去看看
这里报出了error: Microsoft Visual C++ 14.0 or greater is required. Get it with “Microsoft C++ Build Tools”: https://visualstudio.microsoft.com/visual-cpp-build-tools/
这个错误 看的很明显了让你安装visual c++ 14.0 后面的链接十分不友好给了一个下图 你都不知道要安装那个
看这里 有的帖子让你安装个VS 这个跟一下就知道一看就是个开发环境 不可能运行需要开发环境的 所以直接安装运行环境就好了
链接在这里！！！！链接在这里！！！！链接在这里！！！！链接在这里！！！！链接在这里！！！！链接在这里！！！！
https:不要下载//www.microsoft.com不要下载这个/en-us/download/confirmation.aspx?id=48159
https://learn.microsoft.com/zh-CN/cpp不要下载这个/windows/latest-supported-vc-redist?view=msvc-170
上面两个链接我都安装了 但是不通过 是其他up更新的帖子
下面这个有绝对可以解决问题
链接：https://pan.baidu.com/s/1_a4H3TuLQzH7KFjIsKKfOg?pwd=g2qs
因为可能有不止一个环境的缺失这个属于大礼包吧 不能解决请找我
点击后会自动下载一个文件 安装了就可以继续在pip install中继续安装你想安装的第三方库了（可以不重启）

Installing collected packages: Polygon3, opencv-python, onnx, click, matplotlib, onnxruntime, cnstd, cnocr
DEPRECATION: Polygon3 is being installed using the legacy ‘setup.py install’ method, because it does not have a ‘pyproject.toml’ and the ‘wheel’ package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the ‘–use-pep517’ option. Discussion can be found at https://github.com/pypa/pip/issues/8559

关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。

我想解析一个已经存在的.mid文件，改变它的乐器，例如从“acousticgrandpiano”到“violin”，然后将它保存回去或作为另一个.mid文件。根据我在文档中看到的内容，该乐器通过program_change或patch_change指令进行了更改，但我找不到任何在已经存在的MIDI文件中执行此操作的库.他们似乎都只支持从头开始创建的MIDI文件。 最佳答案 MIDIpackage会为您完成此操作，但具体方法取决于midi文件的原始内容。一个MIDI文件由一个或多个音轨组成，每个音轨是十六个channel中任何一个上的
本文主要介绍在使用Selenium进行自动化测试或者任务时，对于使用了iframe的页面，如何定位iframe中的元素文章目录场景描述解决方案具体代码场景描述当我们在使用Selenium进行自动化测试的时候，可能会遇到一些界面或者窗体是使用HTML的iframe标签进行承载的。对于iframe中的标签，如果直接查找是无法找到的，会抛出没有找到元素的异常。比如近在咫尺的例子就是，CSDN的登录窗体就是使用的iframe，大家可以尝试通过F12开发者模式查看到的tag_name,class_name,id或者xpath来定位中的页面元素，会抛出NoSuchElementException异常。解决
