stl10's Issues

Why (0,3,2,1) for transpose and not (0,2,3,1)?

I was looking at https://github.com/mttk/STL10/blob/master/stl10_input.py#L60:

images = np.transpose(images, (0, 3, 2, 1))

is there a reason that you have (0, 3, 2, 1) and not something else?

I noticed that if you change it to (0, 2, 3, 1) the images get flipped. Does it mean that the first 96 that appears from images = np.reshape(everything, (-1, 3, 96, 96)) corresponds to the HEIGHT but the second 96 corresponds to WIDTH? When you transpose it since the 3 goes before the 2 in (0, 3, 2, 1) it made me assume that since the 2 stayed in the same position that it was the height pixel index.

"img" directory not found

There is an error when we run the code with python 3.6.x. It says there is directory not found which needs us to create the 'img' folder in the current working directory.
I think there is os.mkdir('.\img') needed.

Code to get classname folder instead of numbers

Thank you for this script.

If you want to create class subfolders based on class names instead of numbers insert this snippet before the save_images(images, labels) call:

with open('data/stl10_binary/class_names.txt', 'r') as f:
	names = f.read().splitlines()
i2c = {i+1:names[i] for i in range(len(names))}
labels = [i2c[i] for i in labels]

AttributeError: module 'urllib' has no attribute 'urlretrieve'

I tried running the demo but I found the following error:

(venv2) brandomiranda~/Documents/MIT/MEng/hbf_tensorflow_code/tf_tutorials/stl10 $ frameworkpython stl10_input.py

    filepath, _ = urllib.urlretrieve(DATA_URL, filepath, reporthook=_progress)
AttributeError: module 'urllib' has no attribute 'urlretrieve'

did you ever find an error like this before?
