TensorFlow Udacity 1_notmnist - Part 1
Summary of 1_notmnist
Basically 1_notmnist is to learn how to display data in Jupyter Notebook. Besides, it also let us know on sklearn - a python machine library - so that we can then compare with TensorFlow. This is the exact ipynb file at Tensorflow Github Repo.
This is as a form of sharing and discuss on better way to solve 1_notmnist problem. Do not copy and paste directly as it does not help on improving yourself + the answer is not optimized.

# start a docker container docker run -p 8888:8888 -it b.gcr.io/tensorflow-udacity/assignments:latest
Let's take a peek at some of the data to make sure it looks sensible. Each exemplar should be an image of a character A through J rendered in a different >font. Display a sample of the images that we just downloaded. Hint: you can use the package IPython.display.
Solving Problem 1
import os, random dir_name = "notMNIST_large" folder_names = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J"] for folder in folder_names: im_name = random.choice(os.listdir(dir_name + "/" + folder)) im_file = dir_name + "/" + folder + "/" + im_name display(Image(filename=im_file))
Before I get to Problem 1 I have spent a lot of time download the notMNIST_large due to low RAM I have given to my VM that run the docker container.
For the problem part, it teaches us on using
display(Image(filename=im_file)) which is a very useful function of showing image file on Jupyter Notebook.
