6 years ago it may be because data download. i download data manually from http://yann.lecun.com/exdb/mnist/ and changed mnist.py. basic models work. but random_forest still bad.
`
mnist_path = "D:\PYProjects\tensorflow\mnist\"
TRAIN_IMAGES = 'train-images-idx3-ubyte.gz'
TRAIN_LABELS = 'train-labels-idx1-ubyte.gz'
TEST_IMAGES = 't10k-images-idx3-ubyte.gz'
TEST_LABELS = 't10k-labels-idx1-ubyte.gz'
local_file = base.maybe_download(TRAIN_IMAGES, train_dir,
source_url + TRAIN_IMAGES)
local_file=mnist_path + TRAIN_IMAGES with gfile.Open(local_file, 'rb') as f: train_images = extract_images(f)
local_file = base.maybe_download(TRAIN_LABELS, train_dir,
source_url + TRAIN_LABELS)
local_file = mnist_path + TRAIN_LABELS with gfile.Open(local_file, 'rb') as f: train_labels = extract_labels(f, one_hot=one_hot)
local_file = base.maybe_download(TEST_IMAGES, train_dir,
source_url + TEST_IMAGES)
local_file = mnist_path + TEST_IMAGES with gfile.Open(local_file, 'rb') as f: test_images = extract_images(f)
local_file = base.maybe_download(TEST_LABELS, train_dir,
source_url + TEST_LABELS)
local_file = mnist_path + TEST_LABELS with gfile.Open(local_file, 'rb') as f: test_labels = extract_labels(f, one_hot=one_hot) `
when i try basic models, i get follow error.
