TypeError: only integer scalar arrays can be converted to a scalar index

[GregKuhlmann]

Upon running python main.py I get the following error:

('Extracting', 'MNIST_data/train-images-idx3-ubyte.gz')
Traceback (most recent call last):
  File "main.py", line 44, in <module>
    mnist = input_data.read_data_sets("MNIST_data/", one_hot=True)
  File "/Users/kuhlmann/autoencoder_demo/input_data.py", line 150, in read_data_sets
    train_images = extract_images(local_file)
  File "/Users/kuhlmann/autoencoder_demo/input_data.py", line 40, in extract_images
    buf = bytestream.read(rows * cols * num_images)
  File "/usr/local/Cellar/python/2.7.12_1/Frameworks/Python.framework/Versions/2.7/lib/python2.7/gzip.py", line 275, in read

Fixed by following advice here:

[anasvp444]

add [0] to the function _read32 in input_data.py

def _read32(bytestream):
dt = numpy.dtype(numpy.uint32).newbyteorder('>')
return numpy.frombuffer(bytestream.read(4), dtype=dt)[0]
