I followed your instructions to compile TensorFlow for iOS and then put your project into the example folder.

When I compile your project now, I get this error:

This program requires version 3.2.0 of the Protocol Buffer runtime library, but the installed version is 3.1.0.

Do you know the output of your .pb file from quantization is quantized or float?

Is it possible for you to share speed and accuracy measurements of the yolo on ios? I am trying to find a optimal solution for tracking, detecting on mobile phone. It seems very hard to make a real time solution.

The xcodeproject references a file that does not exist and is not used within the project.
But this fie is missing which causes a compile error. The reference should probably be removed therefore:

imagenet_comp_graph_label_strings

I followed the installation steps, but I get a runtime exception when running on the device:

[libprotobuf FATAL /Volumes/build-storage/build/master_iOS-mac/opencv/3rdparty/protobuf/src/google/protobuf/stubs/common.cc:67] This program requires version 3.2.0 of the Protocol Buffer runtime library, but the installed version is 3.1.0. Please update your library. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "/Users/Peter/Downloads/tensorflow-1.2.0/tensorflow/contrib/makefile/gen/proto/tensorflow/core/util/test_log.pb.cc".) libc++abi.dylib: terminating with uncaught exception of type google::protobuf::FatalException: This program requires version 3.2.0 of the Protocol Buffer runtime library, but the installed version is 3.1.0.

(Version verification failed in "/Users/Peter/Downloads/tensorflow-1.2.0/tensorflow/contrib/makefile/gen/proto/tensorflow/core/util/test_log.pb.cc".)

I tried building libprotobuf 3.2 from source but then I have a similar issue that says the library was build against 3.1.
Help would be appreciated, could you perhaps share your project?

I have no quantization folder inside bazel-bin/tensorflow/tools. However, I have it inside tensorflow-master/tensorflow/tools/quantization. I just removed the bazel-bin and simply put tensorflow/tools/quantization/quantize_graph and it tells me can not find the directory or file.
Do you know why it happen.
How am I able to get a quantization folder inside bazel-bin?

You are using quantize_graph tool to quantize the model.
https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/lite
On this website, they are suggesting freeze the graph using .pb and .ckpt, then convert it to .tflite.
I think freeze_graph tool can also generate a quantized model.
Do you know what is the difference?
Where is the .ckpt file for darkflow?
