问题描述：在使用TrOCR预训练模型(如trocr-base-stage1.pt,trocr-base-printed.pt等)时，遇到了一个错误。当运行以下脚本时，会出现以下错误：AssertionError: Could not infer model type from Namespace。

错误发生在以下代码段中：

if __name__ == '__main__':
    model_path = '/content/trocr-base-printed.pt'
    jpg_path = "/content/pan4.jpeg"
    beam = 5
    

model, cfg, task, generator, bpe, img_transform, device = init(model_path, beam)

sample = preprocess(jpg_path, img_transform)

text = get_text(cfg, generator, model, sample, bpe)

print(text)
print('done')

=======================================================================

### | [label] load dictionary: 50265 types

错误原因：在初始化模型时，无法从Namespace中推断出模型类型。
