please follow the install instructions

The installation is not specific to termux on android which only supports pip, any help to get out installed through pip on android

@sheneeb faiss on pip (faiss-cpu and faiss-gpu) is hosted unofficially by kyamagu/faiss-wheels, so it is more appropriate to report the problem there rather than here.

There is a mention of installation on raspberry pi any way to get hold of that
