How to enable the C++ classification sample compilation enabled

[Fanhe0718]

Want to enable macro “TF_SRC_DIR” and compile the C++ classification example, so can anyone give me a simple guide? Thanks a lot.

Follow the steps mentioned here to build C++ classification sample: https://github.com/openvinotoolkit/openvino_tensorflow/blob/master/examples/README.md#c-implementation-for-classification

According to below web guide, can’t compile the C++ classification sample, so can’t find directory “classification_sample” in <path-to-openvino-tesnsorflow-repository>/build_cmake/example/, from “CMakeLists.txt”, I can see that need to enable macro “TF_SRC_DIR”, so how to enable that? ***@***.*** From: Chandrakant Khandelwal ***@***.******@***.***> Sent: Wednesday, November 10, 2021 12:22 AM To: openvinotoolkit/openvino_tensorflow ***@***.***> Cc: He, Fan1 ***@***.***>; Author ***@***.***> Subject: Re: [openvinotoolkit/openvino_tensorflow] How to enable the C++ classification sample compilation enabled (Issue #211) Follow the steps mentioned here to build C++ classification sample: https://github.com/openvinotoolkit/openvino_tensorflow/blob/master/examples/README.md#c-implementation-for-classification — You are receiving this because you authored the thread.

To run the C++ examples you need tensorflow built from source. Copying the build steps from the readme:

1. To built tensorflow from source, please use following script:
   python3 build_tf.py --output_dir "path-to-tensorflow-dir"
   Note: here "path-to-tensorflow-dir" is a user defined location for saving the Tensorflow libs.
   https://github.com/openvinotoolkit/openvino_tensorflow/blob/master/docs/BUILD.md#TensorFlow

2. Once your TF build is successful, pls run the following command:
   python3 build_ovtf.py --use_tensorflow_from_location "path-to-tensorflow-dir"

and it build the OpenVINO integration with Tensorflow library as well as classification samples too, the build_ovtf.py set the TF_SRC_DIR macro in it and you don't need to set that up separately.

Let me know exactly in which step are getting the error? and what is the error?

TF and ovtf all builded successfully, but the macro “TF_SRC_DIR” not enabled in the initial version, so I can’t find the classification sample in the build-complete repo. I just want to how to enable “TF_SRC_DIR”, that it which file I need to modify or need add an option such as “-D TF_SRC_DIR”, thanks.

Check line 517 of the build file: https://github.com/openvinotoolkit/openvino_tensorflow/blob/master/build_ovtf.py
The flag "TF_SRC_DIR" is added automatically, if the tensorflow source location is provided properly.
