Question

我试图在我的Alpine容器中安装DeepSpeech，虽然我似乎满足了文档中的所有要求，但我却“与此Python错误不兼容”。

这是我运行pip install --verbose deepspeech

我似乎这是Windows环境中的常见问题，但这是Alpine基本映像。我想念什么？

Answer 1

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

如果预构建的二进制文件不适用于您的系统，则需要从头开始安装它们。请遵循这些native_client安装说明。

Alpine Linux使用musl libc而不是glibc。适用于“ manylinux”的DeepSpeech Python轮子在Alpine上不起作用。您需要完成源文档中的编译。但是，仍然可能从源代码编译其他Musl libc不兼容性。

如果对Alpine的要求不是很高，那么使用另一个支持预编译轮子的Linux基本映像，您可能会获得更好的安装体验。

Answer 2

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