get_movie_vectors将电影特征转化为向量时报错

[aajingmingtao]

我的版本：paddle-serving-app 0.9.0
paddle-serving-client 0.9.0
paddle-serving-server-gpu 0.9.0.post1028
paddlepaddle-gpu 2.4.2.post117

我想要采用PaddleRec与Milvus深度结合，进行电影推荐。看到官方教程，走的步骤。
首先执行python -m paddle_serving_client.convert --dirname ./movie_model/4/ --model_filename ./movie_model/4/rec_inference.pdmodel --params_filename ./movie_model/4/rec_inference.pdiparams得到的模型，然后执行python get_movie_vectors.py就会报错了：
