Description

I am trying to run the megatron-deepspeed gpt pretrain example with 1 GPU but I get this error. Do I have to change something from the pretrain_gpt.sh file?
assert last_epoch_num_samples < (num_samples_per_epoch + 1),
AssertionError: last epoch number of samples exceeded max value.

Research direction

Start with the Megatron-DeepSpeed GPT pretrain example and inspect pretrain_gpt.sh alongside the reported assertion about last_epoch_num_samples. Reproduce the example with one GPU and determine the conditions that trigger the assertion. Done means the documented example runs without this assertion or clearly identifies the required configuration change.
