包好像有兼容性问题

1.Python版本问题

首先是这里只说了Require Python version <=3.12，但是实际上需要3.8以上，不然有依赖会报错：

后面去包管理中心（https://pypi.org/project/pdf2zh/1.6.9/）看了下，这里确实有说明需要3.8以上。（因为没研究过，不知道pypi这里的说明是不是分开维护的，和github仓库这边的有些差异……）

之后换了，3.11，安装正常

2.pdf2zh命令报错OpenCV bindings requires "numpy" package：

提示没有numpy，但是实际上是有的，不确定是本地环境问题，还是依赖包直接有冲突？

好的，这就修改一下

[Byaidu]

numpy 应该是版本低了，可以重装一下

[yansheng836]

好像不是这个numpy版本低的问题，它当前已经是最新了

不知道了，可能你安装的 python 有问题吧，正常 numpy 引入 typing 不应该报错的

[yansheng836]

卸载干净，又重新安装了个3.12，用上了，感谢。

其实还有个问题，一开始报错，看了这个（https://github.com/Byaidu/PDFMathTranslate/issues/27）之后发现默认是用Google翻译的，fq之后就好了，有点好奇的是为啥这里提示连接问题，里面有个url，却不是google翻译那个呢？
