1.3.2 【Optional execution】 Additional installation steps for processor graphics (GPU)

$ cd /opt/intel/computer_vision_sdk/install_dependencies/
$ sudo -E su
$ uname -r
4.15.0-42-generic #<--- display kernel version sample

### Execute only when the kernel version is older than 4.14
$ ./install_4_14_kernel.sh

$ ./install_NEO_OCL_driver.sh
$ sudo reboot

2. Downgrade to stable OpenCV

Since OpenCV 4.0.0-pre introduced by default had bug in Gstreamer and it did not work properly, we will reinstall OpenCV 3.4.3 on our own.

$ sudo -H pip3 install opencv-python==3.4.3.18
$ nano ~/.bashrc
export PYTHONPATH=/usr/local/lib/python3.5/dist-packages/cv2:$PYTHONPATH

$ source ~/.bashrc

3. Upgrade to Tensorflow v1.11.0

Upgrade to old version Tensorflow v1.9.0, introduced by default, to Tensorflow v1.11.0, as subsequent model optimizer processing will fail.

$ sudo -H pip3 install pip --upgrade

$ python3 -c 'import tensorflow as tf; print(tf.__version__)'
1.9.0 #<--- display Tensorflow version sample

$ sudo -H pip3 install tensorflow==1.11.0 --upgrade
or
$ sudo -H pip3 install tensorflow-gpu==1.11.0 --upgrade

How to check the graph structure of a ".pb" file [Part.2]

Convert to text format.

1. Run graph structure analysis program

$ python3 tfconverter.py
### ".pbtxt" in ProtocolBuffer format is output.
### The size of the generated text file is huge.

How to check the graph structure of a ".pb" file [Part.3]

Use Tensorboard.

1. Build Tensorboard

$ cd ~
$ git clone -b v1.11.0 https://github.com/tensorflow/tensorflow.git
$ cd tensorflow
$ git checkout -b v1.11.0
$ bazel build tensorflow/tensorboard:tensorboard

2. Run log output program for Tensorboard

import tensorflow as tf
from tensorflow.python.platform import gfile

with tf.Session() as sess:
    model_filename ="xxxx.pb"
    with gfile.FastGFile(model_filename, "rb") as f:
        graph_def = tf.GraphDef()
        graph_def.ParseFromString(f.read())
        g_in = tf.import_graph_def(graph_def)

    LOGDIR="path/to/logs"
    train_writer = tf.summary.FileWriter(LOGDIR)
    train_writer.add_graph(sess.graph)

3. Starting Tensorboard

$ bazel-bin/tensorflow/tensorboard/tensorboard --logdir=path/to/logs

4. Display of Tensorboard

Access http://localhost:6006 from the browser.
