TypeError: can't convert np.ndarray of type numpy.object_. The only supported types are: float64, float32, float16, complex64, complex128, int64, int32, int16, int8, uint8, and bool

I encounter this problem when running the following task, but I did not modify any initial configuration after clone this project:

- task:traffic_state_pred
- model: AGCRN
- dataset: METR_LA

complete running command:
`python run_model.py --task traffic_state_pred --model AGCRN --dataset METR_LA`
