It's a speed test for CPP、Python、Numba in the same function.

Run

Step1. Check envirement

Python: 3.9

cStandard: c17

cppStandard: c++14

Step2. Install requirements

pip install -r requirements.txt

Step3. Build CPP

g++ -O3 -Wall -shared -std=c++14 -fPIC `python3 -m pybind11 --includes` gemini.cpp -o gemini`python3-config --extension-suffix` `python3-config --ldflags`

Step4. Run test

python test.py

Result
