What is TensorFlow ResNet?

The TensorFlow ResNet docker image allows querying a TensorFlow server serving the ResNet model. For example, it is very easy to start using the already trained data from the ImageNet image database. For more information check this link.

TL;DR

Before running the docker image you first need to download the ResNet model training checkpoint so it will be available for the TensorFlow Serving server.

$ mkdir /tmp/model-data
$ cd /tmp/model-data
$ wget 'http://download.tensorflow.org/models/official/20181001_resnet/savedmodels/resnet_v2_fp32_savedmodel_NHWC_jpg.tar.gz'
$ tar xzf resnet_v2_fp32_savedmodel_NHWC_jpg.tar.gz --strip-components=2

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-tensorflow-resnet/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
  • All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
  • Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Prerequisites

To run this application you need Docker Engine 1.10.0. Docker Compose is recommended with a version 1.6.0 or later.

How to use this image

Run TensorFlow ResNet client with TensorFlow Serving

Running TensorFlow ResNet client with the TensorFlow Serving server is the recommended way. You can either use docker-compose or run the containers manually.

Run the application using Docker Compose

The main folder of this repository contains a functional docker-compose.yml file. Run the application using it as shown below:

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-tensorflow-resnet/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a new network for the application and the database:
$ docker network create tensorflow-tier
  1. Start a Tensorflow Serving server in the network generated:
$ docker run -d -v /tmp/model-data:/bitnami/model-data -e TENSORFLOW_SERVING_MODEL_NAME=resnet -p 8500:8500 -p 8501:8501 --name tensorflow-serving --net tensorflow-tier bitnami/tensorflow-serving:latest

Note: You need to give the container a name in order to TensorFlow ResNet client to resolve the host

  1. Run the TensorFlow ResNet client container:
$ docker run -d -v /tmp/model-data:/bitnami/model-data --name tensorflow-resnet --net tensorflow-tier bitnami/tensorflow-resnet:latest

Upgrade this application

Bitnami provides up-to-date versions of Tensorflow-Serving and TensorFlow ResNet client, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the TensorFlow ResNet client container. For the Tensorflow-Serving upgrade see https://github.com/bitnami/bitnami-docker-tensorflow-serving/blob/master/README.md#upgrade-this-image

  1. Get the updated images:
$ docker pull bitnami/tensorflow-resnet:latest
  1. Stop your container
  • For docker-compose: $ docker-compose stop tensorflow-resnet
  • For manual execution: $ docker stop tensorflow-resnet
  1. Take a snapshot of the application state
$ rsync -a tensorflow-resnet-persistence tensorflow-resnet-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the TensorFlow Serving data

You can use these snapshots to restore the application state should the upgrade fail.

  1. Remove the currently running container
  • For docker-compose: $ docker-compose rm tensorflow-resnet
  • For manual execution: $ docker rm tensorflow-resnet
  1. Run the new image
  • For docker-compose: $ docker-compose up tensorflow-resnet
  • For manual execution (mount the directories if needed): docker run --name tensorflow-resnet bitnami/tensorflow-resnet:latest

Configuration

Predict an image

Once you have deployed both the TensorFlow Serving and TensorFlow ResNet containers you can use the resnet_client_cc utility to predict images. To do that follow the next steps:

  1. Exec into the TensorFlow ResNet container.
  2. Download an image:
wget https://tensorflow.org/images/blogs/serving/cat.jpg
  1. Send the image to the TensorFlow Serving server.
resnet_client_cc --server_port=tensorflow-serving:8500 --image_file=8500
  1. The model says the image belongs to the category 286. You can check the imagenet classes index to see how the category 286 correspond to a cougar.
calling predict using file: cat.jpg  ...
call predict ok
outputs size is 2
the result tensor[0] is:
[2.41628254e-06 1.90121955e-06 2.72477027e-05 4.4263885e-07 8.98362089e-07 6.84422412e-06 1.66555201e-05 3.4298439e-06 5.25692e-06 2.66782135e-05...]...
the result tensor[1] is:
286
Done.
