Alpine 上的 Mozilla DeepSpeech

Question

我正在尝试在我的 Alpine 容器中安装 DeepSpeech，虽然我似乎满足了文档中的所有要求，但我得到 'not compatible with this Python error'。

这是我运行 pip install --verbose deepspeech

时的日志

我认为这是 Windows 环境中的一个常见问题，但这是一个 Alpine 基础映像。我错过了什么？

Answer 1

deepspeech 仅在 64 位版本中可用。您的 python 可能是 32 位的。用

验证

python -c "import struct; print(struct.calcsize('P') * 8)"

如果显示 32 位，则需要重新安装 64 位 Python。

Answer 2

来自https://github.com/mozilla/DeepSpeech/tree/v0.5.1#installing-bindings-from-source：

If pre-built binaries aren't available for your system, you'll need to install them from scratch. Follow these native_client installation instructions.

Alpine Linux 使用 musl libc 而不是 glibc。 "manylinux" 可用的 DeepSpeech Python 轮子在 Alpine 上不起作用。您需要通过源文档进行编译。但是，仍然可能存在从源代码编译的其他 musl libc 不兼容问题。

如果 Alpine 不是硬性要求，您可能会使用另一个支持 pre-compiled 轮子的 Linux 基础映像获得更好的安装体验。
