说明：

  使用的测试集为从数据集中每10条音频取一条，共874条。

5.准备数据

  生成数据集的list,label_list.txt,train_list.txt,test_list.txt
执行create_data.py即可生成数据列表，里面提供了生成多种数据集列表方式，具体看代码。

python create_data.py

  生成的列表是长这样的，前面是音频的路径，后面是该音频对应的标签，从0开始，路径和标签之间用\t隔开。

dataset/UrbanSound8K/audio/fold2/104817-4-0-2.wav	4
dataset/UrbanSound8K/audio/fold9/105029-7-2-5.wav	7
dataset/UrbanSound8K/audio/fold3/107228-5-0-0.wav	5
dataset/UrbanSound8K/audio/fold4/109711-3-2-4.wav	3

5.特征提取（可选，如果进行特征提取，训练耗时提升36倍）,已提取的特征文件和已训练的模型文件下载。模型放到model目录下，特征放到features目录下。

6.训练,可以通过指定–model_type的参数来指定模型，进行模型训练。

7.测试

  测试采用流式测试的方式，即每次送入模型2秒的音频数据，将音频数据转为[1,1,64,100]维度的张量数据，然后送入到模型中进行推理，每次都很得到推理的结构，可以根据阈值来判断该事件是否发生。
