So when num_workers=2 you have at most 2 workers simultaneously putting data into RAM, not 3. Well our CPU can usually run like 100 processes without trouble and these worker processes aren't special in anyway, so having more workers than cpu cores is ok. Webnum_workers, which denotes the number of processes that generate batches in parallel. A high enough number of workers assures that CPU computations are efficiently managed, i.e. that the bottleneck is indeed the neural network's forward and backward operations on the GPU (and not data generation). ウグイス山形WebIt is a machine-learning specific language and enhances the development process by allowing developers to work on algorithms and machine learning models without … うぐいす岡山
