1）PaddleHub和PaddlePaddle版本：paddlehub==1.6.1，paddlepaddle==1.7.1 2）系统环境：docker镜像 nvidia/cuda:9.0-cudnn7-runtime-centos7，Python 2.7.5

根据ernie_v2_eng_large模型文档跑示例代码，报错如下：

[root@1cab43374dfd ~]# cat test.py
import paddlehub as hub

# Load ernie pretrained model
module = hub.Module(name="ernie_v2_eng_large")
inputs, outputs, program = module.context(trainable=True, max_seq_len=128)

# Must feed all the following tensor of ernie's module need
input_ids = inputs["input_ids"]
position_ids = inputs["position_ids"]
segment_ids = inputs["segment_ids"]
input_mask = inputs["input_mask"]
# task_ids is not necessary during finetuning
task_ids = inputs["task_ids"]

[root@1cab43374dfd ~]# python test.py
