This repo is modified based on https://github.com/erikjandevries/mnist-learning-docker.

TLDR: If you don't have nvidia-docker2 installed you need to have that first, refer to https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html for more details, then all you need to do is as following:

  1. install python3, pip , then you need to install pip install imageio and pip install pillow
  2. clone the repo to local
  3. cd <project_root>/prepare, run python download-mnist-data.py
  4. cd <project_root>/basic, run ./build.sh
  5. run time ./cpu_run.sh to train the model using cpu and get the total training time
  6. run time ./gpu_run.sh to train the model using gpu and get the total training time
  7. if you want to check the gpu power and temperature run watch -n 2 nvidia-smi in another tty during the training

mnist-learning-docker

Learning MNIST using TensorFlow in a Docker container

Prepare

You will need the MNIST data set in order to run these Docker images

You can use the provided scripts, based on: https://github.com/datapythonista/mnist, to download the MNIST dataset from: http://yann.lecun.com/exdb/mnist/

Running the script download-mnist-data.py --out-dir=<out_dir> downloads the training and test sets into the required folder/file structure:

  • <out_dir> / <train|test> / <label> / <image_index>.png

By default <out_dir>="/mnt/data/Data/mnist"

Basic Docker image

In this image, you will define and train a TensorFlow model using Keras. After preparing the data, you will need to run the following three scripts.

Build the Docker image

To build the Docker image, run the build.sh script.

Train the model

To train the model, run the Docker image with the train.sh script.

Depending on your hardware, this will take a while. With an Nvidia Geforce 1070 it takes about 25s per epoch. By default the script is set up to run for 3 epochs.

Test predictions

To test the predictions of the model, run the Docker image with the test_predictions.sh script.

This will load the pretrained model from disk and test the predictions on 10 batches of image. For each failed prediction, the image will be displayed, and the true and predicted labels will be printed to the console.
