The training of the models with EfficientNet-V2-B3 per epoch took an average of 2 days and 3 hours on a TPU pod slice V3-32. All training processes were moved to a TPU pod slice V3-256 to speed up training. Using EfficientNet-V2-B3, a model could be trained within 12 hours and 30 minutes on average per epoch after changing the training device. For the model with EfficientNet-V2-S as the encoder, it took 15 hours and 26 minutes on average to train each epoch, while for the model with EfficientNet-V2-M as the encoder, it required 1 day and 7 hours.
