efficient net 4 and resnet 50

[georgeper2001]

Is efficient net 4 or efficient net 0 for Chip Classification and resnet 50 and resnet 18 are used for Object Detection?
can you use efficient net 4 for Object?

For chip classification, the default model is a ResNet (see available sizes here). An example of using an EfficientNet can be seen here.

For object detection, the default model is a FasterRCNN. Using an external model is trickier; see example here.
