pickle.load(mnist_pickle) returns UnicodeDecodeError: 'ascii' codec can't decode byte 0x90 in position 614: ordinal not in range(128) about ai-for-beginners HOT 3 OPEN

I see couple of ways of fixing issue:

• bring back mnist.pkl.gz to the repository (since it's missing currently) and make sure accessing fields by strings works there
• change to code to access data using integers, not strings (this seem to work):

print(MNIST[0][0][0][130:180])
print(MNIST[0][1][0])
features = MNIST[0][0].astype(np.float32) / 256.0
labels = MNIST[0][1]
fig = pylab.figure(figsize=(10,5))
for i in range(10):
ax = fig.add_subplot(1,10,i+1)
pylab.imshow(features[i].reshape(28,28))
pylab.show()

i fixed the 'ascii' code error by specifying the encoding parameter: MNIST = pickle.load(mnist_pickle, encoding='latin1')

additional info:

mnist.pkl.gz is not available in the original location, so I downloaded it from
https://github.com/mnielsen/neural-networks-and-deep-learning/blob/master/data/mnist.pkl.gz

I assume the data is structured differently in this file.
