我在 SO 上看到了很多关于这个问题的问题,但没有一个得到解答(或者解决方案不起作用),我不知道为什么。人们不断遇到这个错误,但没有提供解决方案。从过去的几天来看,即使我遇到了这个错误(注意:它似乎在我的物理设备上工作正常(不是在调试时,它只有在我释放它时才工作),但在 android 模拟器上却不起作用,所以我很确定我的互联网工作正常):
Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info.

我正在尝试生成长 PDF 的摘要。所以,我所做的,首先使用pdfminer.six库将我的 pdf 转换为文本。接下来,我使用了此处讨论中提供的 2 个函数。

这是一个输入图像,我得到的预测为 2791 2g rj14
尽你所能,ocr 做得很好,但安排被破坏了(破坏了整个目的)。有时它会以正确的顺序输出,但有时却不会,所以当它没有以正确的顺序输出时,我正在尝试开发一种算法,该算法将预测num_plate字符串作为输入并根据我的国家/地区重新排列它(印度)。
