caffe调试：registry失败

防止某一层未注册:

也就是下面的：

I0808 16:09:36.428869 12912 layer_factory.hpp:77] Creating layer data
F0808 16:09:36.428869 12912 layer_factory.hpp:81] Check failed: registry.count(type) == 1 (0 vs. 1) Unknown layer type: MemoryData (known types: )
*** Check failure stack trace: ***

• 1
• 2
• 3

只要加上以下就好，适当调整。
