I have temporarily solved this issue by changing num_workers=4 and prefetch=250 to num_workers=2 and prefetch=125. However, I'm not sure why setting a higher number of num_workers would lead to this error. It seems that different numbers of GPU cards need to match the appropriate number of num_workers.

may some oom occurs in training,

 num workers * gpus <= cpus cores

I am using a total of 4 machines, each equipped with 4 V100 GPUs with 16GB of memory and 100 cores of dedicated CPU.
