kivy 中没有名为“numpy.core._multiarray_umath”的模块

I keep getting the below error when trying to import numpy in kivy on an android device.尝试在 android 设备上的 kivy 中导入 numpy 时，我不断收到以下错误。

No module named 'numpy.core._multiarray_umath'

Why am I getting this error if I already installed numpy where the main.py file is located and I also made sure the file it is trying to import (_multiarray_umath) is located in the numpy library before building with buildozer, that is -> _multiarray_umath.cpython-36m-x86_64-linux-gnu.so located in numpy/core ?如果我已经在 main.py 文件所在的位置安装了 numpy，并且在使用 buildozer 构建之前，我还确保它尝试导入的文件 (_multiarray_umath) 位于 numpy 库中，即 -> _multiarray_umath ，为什么会出现此错误.cpython-36m-x86_64-linux-gnu.so位于numpy/core 中？ Thanks in advance.提前致谢。

The file you talk about is a desktop linux binary, not compatible with your android device.您谈论的文件是桌面 linux 二进制文件，与您的 android 设备不兼容。 That is why it didn't work on android and (per the comments) the fix was to put numpy in the requirements so that an android version was built and included by buildozer.这就是为什么它在 android 上不起作用，并且（根据评论）修复是将 numpy 放在要求中，以便 buildozer 构建并包含一个 android 版本。

Listing numpy in the buildozer.spec file fixed the error, but I can't seem to get tensorflow to compile in kivy for android.在 buildozer.spec 文件中列出 numpy 修复了错误，但我似乎无法让 tensorflow 在 kivy for android 中编译。 Does tensorflow not work in kivy on android? tensorflow 在 android 上的 kivy 中不起作用吗？

Tensorflow is not currently supported.目前不支持 Tensorflow。 Apparently tensorflow lite works, but you need to include it via gradle and write some java wrapper code to access it.显然 tensorflow lite 可以工作，但是您需要通过 gradle 包含它并编写一些 java 包装器代码来访问它。
