TorchViTDetPredictor parse input error

[Cathy0908]

When i use TorchViTDetPredictor to predict my images, the inputs cannot be parsed.
I tried two input formats.

Format 1: inputs is np.ndarray:

Raise KeyError: 'LoadImageFromWebcam is not in the pipeline registry'

Format 1: inputs is local file path:

Raise ValueError: unknown url type: '/000000037777.jpg'

My full code is as follows:

import os
import numpy as np
from PIL import Image
from easycv.predictors.detector import TorchViTDetPredictor

model_path='./vitdet_maskrcnn.pt'
predictor = TorchViTDetPredictor(model_path = model_path)
img = './000000037777.jpg'

# format 1
input_data_list = [img]  
# format 2
input_data_list = [np.asarray(Image.open(img))]

output_list = predictor.predict(input_data_list)
print(output_list)
