latest docker image from paddlepaddle/paddle:latest can't import fluid

[jetfuel]

I am trying to run the paddle docker image to test paddle fluid.
So first I pull the docker images with

docker pull paddlepaddle/paddle

Once the update is completed. I tried to run paddlepaddle/paddle:latest and import paddle.fluid and got the following error.

Looks like the linking is missing the tensorrt_engine_op.h. Since tensorrt_engine_op.h is a pretty new file. I suspect that we just miss the configuration for it.

It's weird, the CI system should have tested such cases with python unit tests.
I found something wrong with the CMakeList.txt and will open a PR latter.
