The batch sizes are not enough. Assume auto for those not spefified.

i assign
"init_batch_size": [8],
"sys_batch_size": [8,8,8,8],

in the param.json when using dpgen, then a error message was reported :

Description

/home/kemove/intel/intelpython3/lib/python3.6/site-packages/dpgen/generator/run.py:250: UserWarning:

The batch sizes are not enough. Assume auto for those not spefified.

then i changed that :
"init_batch_size": ["auto"],
"sys_batch_size": ["auto"],

still the same error message was reported. what batch_size this message actually mean?

then i delete all of the command about batch_size to let them to be defalut, then another error was reported :

it seems a error about box?

What's the length of your init_data_sys and sys_configs? They should have the same length as init_batch_size and sys_batch_size.

thank you, i fixed it
