LoadCombine Operator.
|
|
|
|
LoadCombine operator loads LoDTensor variables from a file, which could be
|
|
loaded in memory already. The file should contain one or more LoDTensors
|
|
serialized using the SaveCombine operator. The
|
|
LoadCombine operator applies a deserialization strategy to appropriately load
|
|
the LodTensors, and this strategy complements the serialization strategy used
|
|
in the SaveCombine operator. Hence, the LoadCombine operator is tightly coupled
|
|
with the SaveCombine operator, and can only deserialize one or more LoDTensors
|
|
that were saved using the SaveCombine operator.
