Memory Data Layer

• Layer type: MemoryData
• Doxygen Documentation
• Header: ./include/caffe/layers/memory_data_layer.hpp
• CPU implementation: ./src/caffe/layers/memory_data_layer.cpp

The memory data layer reads data directly from memory, without copying it. In order to use it, one must call MemoryDataLayer::Reset (from C++) or Net.set_input_arrays (from Python) in order to specify a source of contiguous data (as 4D row major array), which is read one batch-sized chunk at a time.

Parameters

• Parameters (MemoryDataParameter memory_data_param)
• From ./src/caffe/proto/caffe.proto:

{% highlight Protobuf %} {% include proto/MemoryDataParameter.txt %} {% endhighlight %}

• Parameters
  • Required
    • batch_size, channels, height, width: specify the size of input chunks to read from memory
