NVidia's TensorRT 4 tutorial halts showing: UFF parsing failed

Hello,

I’ve been trying to run the TensorRT tutorial (https://docs.nvidia.com/deeplearning/sdk/tensorrt-api/topics/topics/workflows/tf_to_tensorrt.html) but the program halts at:

engine = trt.utils.uff_to_trt_engine(G_LOGGER, uff_model, parser, 1, 1 << 20)

The program produces the following error:

---------------------------------------------------------------------------
AssertionError                            Traceback (most recent call last)
<ipython-input-21-d6e6de8c521d> in <module>()
----> 1 engine = trt.utils.uff_to_trt_engine(G_LOGGER, uff_model, parser, 1, 1 << 20)

/usr/lib/python2.7/dist-packages/tensorrt/utils/_utils.py in uff_to_trt_engine(logger, stream, parser, max_batch_size, max_workspace_size, datatype, plugin_factory, calibrator)
    225         filename, line, func, text = tb_info[-1]
    226 
--> 227         raise AssertionError('UFF parsing failed on line {} in statement {}'.format(line, text))
    228 
    229 

AssertionError: UFF parsing failed on line 219 in statement assert(engine)

I’m not yet very familiar with TensorRT. Could any one provide me with additional information to solve this?

Library information:
Tensorflow: 1.4.1
TensorRT: 4.0.0.3
Cuda: 8.0.33
cuDNN: 6.0.21

We created a new “Deep Learning Training and Inference” section in Devtalk to improve the experience for deep learning and accelerated computing, and HPC users:
https://devtalk.nvidia.com/default/board/301/deep-learning-training-and-inference-/

We are moving active deep learning threads to the new section.

URLs for topics will not change with the re-categorization. So your bookmarks and links will continue to work as earlier.

Hi @Koen-fj have you solved this problem?
If you have resolved it ,please share the solution.
