I have met the
PluginFieldCollection in the TensorRT Developer Guide,
samplePlugin and the
sampleUffSSD samples. I noticed that in the
FlattenConcat plugins included in
sampleUffSSD sample, this class defined a static member variable whose type is
PluginFieldCollection and this member is used as the construct function parameters.
But I still cannot figure out the usage of this member, especially, when and how this static member field is used. Or, is it used during serialize
Engine or deserialization when calling
serialize(), or when calling
getOutputDimensions() … ?
This object has confused me very long time, thanks for any explains.
