• 标题：调用fluid.layers.lstm时报NameError: name 'core' is not defined

• 版本、环境信息：    1）PaddlePaddle版本：PaddlePaddle 1.7.0    2）GPU：Tesla v100 3) 环境：AIstudio

• 问题描述：调用fluid.layers.lstm时报NameError: name 'core' is not defined

• 调用代码 _, last_h, _ = fluid.layers.lstm( input=out, init_h = init_h, init_c = init_c, max_len = 32, hidden_size =768, num_layers = 2, dropout_prob = 0.1, #is_bidirec = True )
