tensorflow: Error_Converting_TliteFormat

…## System information##… -Python -2.7.12 -OS -Ubuntu 16.04 -Tensorflow version-1.4.0 -Bazel version-0.8.0 …##Description ###…

I went through the following link and =>https://codelabs.developers.google.com/codelabs/tensorflow-for-poets/#3 and successfully retrained the last layer of the model.
Now i was trying to use that retrained.pb file and convert into.tlite format. =>https://github.com/tensorflow/tensorflow –Downloaded the tensorflow-master directory. –Install Bazel (0.8.0) –Then, using the retrained.pb file,trying to do model format conversion –Downloaded the checkpoints from =>https://github.com/tensorflow/models/blob/master/research/slim/nets/mobilenet_v1.md But got stucked while running the command for conversion.[bazel-bin/tensorflow/python/tools/freeze_graph --input_graph=/home/ee210201/tensorflow-for-poets-2/tf_files/retrained_graph.pb --input_checkpoint=/tmp/checkpoints/mobilenet_v1_0.50_224.ckpt.data-00000-of-00001 --input_binary=true --output_graph=/tmp/checkpoints/frozen_mobilenet.pb --output_node_names=Softmax}

…### Source code ##… 1. (tensorflow) root@pcz-ee210201:/u/tensorflow-master# bazel build -c opt --copt=-msse4.1 --copt=-msse4.2 tensorflow/python/tools:freeze_graph

But while running the below script [To convert into .tlite format] ,i was unable to resolved the following error?

I had this issue because I installed “libtensorflow_framework.so” in my system. Removing this library out of “/usr/local/lib” solved this problem for me.

About the link error of tensorflow/serving#684 , I fixed adding deps on BUILD file under “./tensorflow/tensorflow/contrib/data/” as below.

28 tf_custom_op_library( 29 name = “_prefetching_ops.so”, 30 srcs = [“ops/prefetching_ops.cc”], 31 deps = [ 32 “//tensorflow/contrib/data/kernels:prefetching_kernels”, 33 “@protobuf_archive//:protobuf”, 34 ], 35 )

But it makes core dump…

I am unable to resolve the issue.

I have same problem. No updates?

We started seeing the same error in TensorFlow Serving at around the same time when running an example client - https://github.com/tensorflow/serving/issues/684

tensorflow.python.framework.errors_impl.NotFoundError: /tensorflow/bazel-bin/tensorflow/examples/image_retraining/retrain.runfiles/org_tensorflow/tensorflow/contrib/data/python/ops/../../_prefetching_ops.so: undefined symbol: _ZN6google8protobuf8internal26fixed_address_empty_stringB5cxx11E

Any ideas?
