TensorFlow SSD训练自己的数据 checkpoint问题 40C

1、参考教程:https://blog.csdn.net/liuyan20062010/article/details/78905517
2、一直到训练成功!
3、导入模型测试,代码

# Restore SSD model.
ckpt_filename = '../train_model/model.ckpt-100'
# ckpt_filename = '../checkpoints/VGG_VOC0712_SSD_300x300_ft_iter_120000.ckpt'
isess.run(tf.global_variables_initializer())
saver = tf.train.Saver()
saver.restore(isess, ckpt_filename)

4、错误信息:

图片说明

5、经网上查阅,说是修改了模型结构的问题,但是只是按教程上面修改了类别数,且训练成功了。其他均未修改。

亨利先生 不是要用原本的ssd300模型,这个我跑通了。我现在是自己训练好了模型,然后再导入自己的模型的时候,它报了这个错误。应该说这个错误是说网络结构变化了,但是训练完就直接导入,网络结构不会发生变化啊。
