model = resnet50(pretrained=True, num_classes=38)

model = paddle.Model(model)

# 模型训练配置
model.prepare(......) # 评估指标

model.fit(.......)

model.save('/home/aistudio/model')

model.load('/home/aistudio/model')

以上操作皆成功，之后预测报错。

#预测
result = model.predict(val_dataset)

#报错

AttributeError: 'Model' object has no attribute '_place'

/opt/conda/envs/python35-paddle120-env/lib/python3.7/site-packages/paddle/hapi/model.py in predict(self, test_data, batch_size, num_workers, stack_outputs, callbacks)
1684 test_data,
1685 batch_sampler=test_sampler,
-> 1686 places=self._place,
1687 num_workers=num_workers,

这是怎么回事呢？谢谢
