--------------------------------------------------------------------------------
In which compute environment are you running?
This machine
--------------------------------------------------------------------------------
multi-GPU
How many different machines will you use (use more than 1 for multi-node training)? [1]: 1
Should distributed operations be checked while running for errors? This can avoid timeout issues but will be slower. [yes/NO]: no
Do you wish to optimize your script with torch dynamo?[yes/NO]:no
Do you want to use DeepSpeed? [yes/NO]: no
Do you want to use FullyShardedDataParallel? [yes/NO]: no
Do you want to use Megatron-LM ? [yes/NO]: no
How many GPU(s) should be used for distributed training? [1]:2
What GPU(s) (by id) should be used for training on this machine as a comma-seperated list? [all]:0,1
--------------------------------------------------------------------------------
Do you wish to use FP16 or BF16 (mixed precision)?
no
