ERNIE-GEN 运行预置的文本生成任务在评估验证集阶段报错

在AIStudio运行https://github.com/PaddlePaddle/ERNIE/tree/94a2367ba7f0f83b48330233450ea095d8dc9382/applications/tasks/text_generation 中的生成任务在验证集评估阶段报错

评估过程会在output文件夹中生成evaluate_step 文件，但是是空的。。 请问一下这个任务的代码应该运行在哪个版本的paddlepaddle-gpu 和paddlehub 中的呢 我的运行环境是paddlepaddle-gpu==2.3.2， paddlehub==2.3.0
