# Load the data set

# Shuffle the data
X, Y = shuffle(X, Y)

# Make sure the data is normalized

# Create extra synthetic training data by flipping, rotating and blurring the

# Define our network architecture:

# Input is a 32x32 image with 3 color channels (red, green and blue)
network = input_data(shape=[None, 32, 32, 3],
data_preprocessing=img_prep,
data_augmentation=img_aug)

# Step 1: Convolution
network = conv_2d(network, 32, 3, activation='relu')

# Step 2: Max pooling
network = max_pool_2d(network, 2)

# Step 3: Convolution again
network = conv_2d(network, 64, 3, activation='relu')

# Step 4: Convolution yet again
network = conv_2d(network, 64, 3, activation='relu')

# Step 5: Max pooling again
network = max_pool_2d(network, 2)

# Step 6: Fully-connected 512 node neural network
network = fully_connected(network, 512, activation='relu')

# Step 7: Dropout - throw away some data randomly during training to prevent over-fitting
network = dropout(network, 0.5)

# Step 8: Fully-connected neural network with two outputs (0=isn't a bird, 1=is a bird) to make the final prediction

# Tell tflearn how we want to train the network

错误：
UnicodeDecodeError: 'ascii' codec can't decode byte 0xa8 in position 6: ordinal not in range(128)
该如何更改代码

Answer 1

加入：
import sys
defaultencoding = 'utf-8'
if sys.getdefaultencoding() != defaultencoding:
reload(sys)
sys.setdefaultencoding(defaultencoding)
