以下是原帖,上边该补充的都说了=================分割线=============
谷歌在大型图像数据库ImageNet上训练好了一个Inception-v3模型,这个模型我们可以直接用来进来图像分类。下载地址:https://storage.googleapis.com/download.tensorflow.org/models/inception_dec_2015.zip下载完解压后,得到几个文件:
其中的classify_image_graph_def.pb 文件就是训练好的Inception-v3模型。
imagenet_synset_to_human_label_map.txt是类别文件。
随机找一张图片:如对这张图片进行识别,看它属于什么类?
代码如下:先创建一个类NodeLookup来将softmax概率值映射到标签上。
然后创建一个函数create_graph()来读取模型。
最后读取图片进行分类识别:

以下是亲自验证,上图====================分割线====================================
上面这张图,识别成seashore,还是挺准的。
注意,我是windows环境运行的,目录要用r'路径'或者双反斜杠"\"!不然总会出如下错误
tensorflow.python.framework.errors_impl.NotFoundError: NewRandomAccessFile failed to Create/Open: D: f.jpg : ϵ ͳ\udcd5Ҳ\udcbb\udcb5\udcbdָ\udcb6\udca8\udcb5\udcc4\udcceļ\udcfe\udca1\udca3; No such file or directory
还有,我目前不知道为什么一把图片弄个路径就出错,目前我是直接放文件夹里才能用的。不然就是下面那个错误
#读取图片image_data = tf.gfile.FastGFile('1.jpg', 'rb').read() #直接的'1.jpg'tensorflow.python.framework.errors_impl.InvalidArgumentError: NewRandomAccessFile failed to Create/Open: D:\tf\1.jpg : \udcceļ\udcfe\udcc3\udcfb\udca1\udca2Ŀ¼\udcc3\udcfb\udcbb\udcf2\udcbe\udced\udcb1\udcea\udcd3\udcb2\udcbb\udcd5\udcfdȷ\udca1\udca3
