Your Problem

1. You are using Python on macOS M1 (or M2, etc) and are trying to install a Python library which uses a native library.
2. You install the Python library (e.g. using pip) and the native library (using Homebrew).
3. You get an error saying that the native library cannot be located even though it's installed using Homebrew.

Example: You are trying to use e.g. pyfluidsynth. You've installed pyfluidsynth with pip, and also ran brew install fluidsynth. However, import fluidsynth still gives an error:

ImportError: Couldn't find the FluidSynth library.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
