| Software | Version |

| CUDA | 10.2 |
## 1.爲什麼在擴展Node.js類時，我們將變量包裹在大括號中，如{EventEmitter} = require 'events'

{EventEmitter} = require 'events' 

class Rooster extends EventEmitter 
    constructor: -> 
    @on 'wake', -> console.log 'COCKADOODLEDOO!' 

(foghorn = new Rooster).emit 'wake' # COCKADOODLEDOO! 

此：

{EventEmitter} = require 'events' 

相當於這個JavaScript：

var EventEmitter; 
EventEmitter = require('events').EventEmitter;

## 2.Sequelize: difference of DataTypes and Sequelize
The second parameter in both of them is just the sequelize package itself

## 3.Sequelize logs question marks on the console instead of the values
logQueryParameters: true,

## 2.安裝YOLO環境需求
* CMake >= 3.12
* CUDA 10.0 (For GPU)
* OpenCV >= 2.4 (For CPU and GPU)
* cuDNN >= 7.0 for CUDA 10.0 (for GPU)
* OpenMP (for CPU)
* Other Dependencies: make, git, g++
