基本配置：

Anaconda 3 4.2.0（python3.5）

注意：

1、代码存放至全英文目录下；

2、电脑管家之类的安全软件暂时关闭（因为发布出来的exe文件属于可执行文件，电脑管家可能会认为发布出来的文件为病毒，自动删除）

具体操作步骤如下：

1、写好的python代码，存放至全英文的目录下：

import keras
from keras.models import Sequential
import numpy as np
import pandas as pd
from keras.layers import Dense
import random
import matplotlib.pyplot as plt
from tensorflow.examples.tutorials.mnist import input_data
from tkinter import filedialog
import tkinter.messagebox #这个是消息框，对话框的关键
file_path = filedialog.askdirectory()

mnist = input_data.read_data_sets(file_path, validation_size=0)

#随机挑选其中一个手写数字并画图
num = random.randint(1, len(mnist.train.images))
img = mnist.train.images[num]
plt.imshow(img.reshape((28, 28)), cmap='Greys_r')
plt.show()

x_train = mnist.train.images
y_train = mnist.train.labels
x_test = mnist.test.images
y_test = mnist.test.labels

#reshaping the x_train, y_train, x_test and y_test to conform to MLP input and output dimensions
x_train = np.reshape(x_train, (x_train.shape[0], -1))
x_test = np.reshape(x_test, (x_test.shape[0], -1))
y_train = pd.get_dummies(y_train)
y_test = pd.get_dummies(y_test)

#performing one-hot encoding on target variables for train and test
y_train=np.array(y_train)
y_test=np.array(y_test)
#defining model with one input layer[784 neurons], 1 hidden layer[784 neurons] with dropout rate 0.4 and 1 output layer [10 #neurons]
model=Sequential()
model.add(Dense(784, input_dim=784, activation='relu'))
keras.layers.core.Dropout(rate=0.4)
model.add(Dense(10,input_dim=784,activation='softmax'))
# compiling model using adam optimiser and accuracy as metric
model.compile(loss='categorical_crossentropy', optimizer="adam", metrics=['accuracy'])
# fitting model and performing validation
model.fit(x_train, y_train, epochs=20, batch_size=200, validation_data=(x_test, y_test))
y_test1 = pd.DataFrame(model.predict(x_test, batch_size=200))
y_pre = y_test1.idxmax(axis = 1)
result = pd.DataFrame({'test': y_test, 'pre': y_pre})
tkinter.messagebox.showinfo('Message', 'Completed!')

2、通过命令行，按照pyinstaller

pip install pyinstaller

3、命令行打包文件

先切换路径至python代码所在目录，执行语句：

pyinstaller -F -w xxx.py

4、等待打包完成，会生成一个build文件夹和一个dist文件夹，exe可执行文件就在dist文件夹里，如果程序引用有资源，则要把资源文件放在这个exe正确的相对目录下。

5、运行exe文件。

有时运行文件会出错，此时需要拷贝下图所示的文件夹至exe文件所在目录

运行成功！
