random_distortion(probability, grid_height, grid_width, magnitude)
最终选择参数为
p.random_distortion(probability=0.8, grid_height=3, grid_width=3, magnitude=6)

其他参数效果:
magnitude和grid_width,grid_height越大,扭曲程度越大
p.random_distortion(probability=0.6, grid_height=6, grid_width=6, magnitude=5)

random_erasing(probability, rectangle_area)
rectangle_area表示覆盖区域的比例,值越大比例越大。但是设置为1的时候并不是全覆盖,不知道为什么,反正也没必要弄清楚
p.random_erasing(1,1)

zoom_random(probability, percentage_area)
放大图片,然后按照percenta_area的比例对图片进行crop。
p.zoom_random(probability=1, percentage_area=0.2)
