registry.count(type) == 1 (0 vs. 1) Unknown layer type: MemoryData (known types: )

[Joya Chen]

When I add code just like

namespace caffe
{
extern INSTANTIATE_CLASS(MemoryDataLayer);
REGISTER_LAYER_CLASS(MemoryData);
}
then ......
Check failed: registry.count(type) == 0 (1 vs. 0) Layer type MemoryData already registered.
I'm crazy......Hope for your answer.~~

Same problem here, but with "Input" layer.

@lopho
I guess I have solved it....
Just add extern INSTANTIATE_CLASS(MemoryDataLayer); only...
you can add
namespace caffe{
.....
REGISTER_LAYER_CLASS(Input);}
Hope to help you

Ah, no, sorry I misread your original bug report. My problem is a different one entirely.
