I got this
Training images has shape: (27455, 28, 28) and dtype: <U3
Training labels has shape: (27455,) and dtype: <U2
Validation images has shape: (7172, 28, 28) and dtype: <U3
Validation labels has shape: (7172,) and dtype: <U2
but expected output is this
Training images has shape: (27455, 28, 28) and dtype: float64
Training labels has shape: (27455,) and dtype: float64
Validation images has shape: (7172, 28, 28) and dtype: float64
Validation labels has shape: (7172,) and dtype: float64
where I am going wrong??
