 **Note:**
 1) As the global batch size  (batch_size x num_devices) is an important hyper-parameter, it is recommended to keep the global batch size unchanged for reproduction or adjust the learning rate linearly to a new global batch size.
-2) The current configuration with a batch_size of 512, was initially set for a machine with 64GB of VRAM. To avoid running out of memory (OOM) on machines with smaller VRAM, consider reducing the batch_size to 256 or lower.

To avoid running out of memory (OOM) on machines with smaller VRAM, consider reducing the batch_size to 256 or lower. Simultaneously, to maintain the consistency of training results, please scale the learning rate down proportionally with decreasing batch_size.
