Let’s split package names by components:
- numpy — package name
- 1.13.3 — package version
- cp27 — the package was compiled to be used with this version of Python
- cp27mu — compilation flags
- linux — operating system
- armv7l — processor architecture
This means that package numpy contains binary extensions written in C and compiled for specific processor, OS and Python version.
The following package is pure Python:
- protobuf — name
- 3.4.0 — version
- py2.py3 — the package is written in highly portable manner and is suitable for both major versions of Python
- none — is not OS-specific
- any — suitable to run on any processor architecture
