🐛 Bug Description

To Reproduce

Steps to reproduce the behavior:

  1. set batch size of model as 2000
  2. set len of infer dataset as 10001
  3. error occur

reason: infer dataset will be split as 5*2000+1, 2000 will be shaped as np.array vector, and 1 will be shaped as np.array scalar.
Calling np.concatenate between vector and scalar will raise error.

Expected Behavior
