batch_size

[Pumpkin123709]

When I set batch_size to 8, the shape of the input_ids of the model's input is [9,n]. The first dimension of input_ids is always one more than bs.

The reason is that: not every batch have location input or output data, which will lead to a running error caused by partially trained modules (e.g., box decoder can not be trained if there are no location out data). Therefore, we additionally include a mock data item to avoid the error. The weight of the data item for loss calculation is set to zero.
