本文介绍使用飞桨EasyEdge平台部署蘑菇分类模型的流程。先定义图像分类任务，解压并标注蘑菇数据集，划分训练集和验证集，定义数据集类并做图像增强。选用mobilenet_v2网络，配置优化器训练模型，最后保存为静态图，通过EasyEdge平台完成部署，操作简洁。

飞桨最近新上了EasyEdge端与边缘AI服务平台，这对于新手来说非常友好
在原来我们开发了模型之后，没有办法快速部署到手机上
现在有了EasyEdge这个平台，直接在EasyEdge端与边缘AI服务平台部署就可以了，操作十分简洁流畅！下面以一个示例来给大家展示：
对于一个任务，当你想使用深度学习来解决时，一般流程如下：
①问题定义->②数据准备->③模型选择与开发->④模型训练和调优->⑤模型评估测试->⑥部署上线
本项目中的蘑菇的分类的本质是图像分类任务，采用轻量级卷积神经网络mobilenet_v2进行相关实践。
我们将网上获取的数据集以压缩包的方式上传到aistudio数据集中，并加载到我们的项目内。
在使用之前我们进行数据集压缩包的一个解压。

我们先看一下解压缩后的数据集长成什么样子。

img_path = os.path.join('work/mushrooms_train', path) if os.path.isdir(img_path):

img = Image.open(os.path.join(img_path, random.choice(img_paths)))
imgs.append((img, path))
f, ax = plt.subplots(3, 3, figsize=(12,12))for i, img in enumerate(imgs[:9]):
ax[i//3, i%3].imshow(img[0])

ax[i//3, i%3].set_title('label: %s' % img[1])
plt.show()

接下来我们使用标注好的文件进行数据集类的定义，方便后续模型训练使用。
