I am trying to install DeepSpeech in my Alpine container, and while I seem to fulfill all of the requirements according to the documentation, I get 'not compatible with this Python error'.
Here is the log from when I run pip install --verbose deepspeech

I seems that this is a common issue on a Windows environment, but this is a Alpine base image. What am I missing?
From 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 uses the musl libc instead of glibc. The available DeepSpeech Python wheels for "manylinux" won't work on Alpine. You'll need to go through the compiling from source documentation. However, there still may be other musl libc incompatibilities compiling from source.
If Alpine is not a hard requirement you are likely to have a much better installation experience using another Linux base image that supports the pre-compiled wheels.
