Hadoop on Windows cmd, one mapper and multiple inputs, Error: subprocess failed

Question

I want to execute a Python file which is related to machine learning and as you know there are two files as inputs (train and test) which are important to make learning process. Also I have no reduce file.

I have three doubts to run my command:

1. Using two input files, I used -input file1 -input file2 according to Using multiple mapper inputs in one streaming job on Hadoop?
2. Turn off reduce, I used -D mapred.reduce.tasks=0 according to How to write 'map only' hadoop jobs?
3. How to make flush my "sys.stdin" when I want to read next input? Indeed I used sys.stdout.flush() in my Python code.

This is my command on cmd Windows:

D:\hadoop\bin\hadoop jar D:\hadoop\share\hadoop\tools\lib\hadoop-streaming-2.3.0.jar 
-D mapred.reduce.tasks=0
-file /in/Deeplearning.py -mapper "python Deeplearning.py" 
-input /in/train.csv -input /in/test.csv 
-output /output

I use: Windows 10 64bit Python 3.6 and my IDE is spyder 3.2.6, Hadoop 2.7.2, Java jdk1.8.0_161

This is my Python code:

import sys
import numpy as np
from numpy.random import permutation
import pandas as pd
import tflearn
from tflearn.layers.core import input_data,dropout,fully_connected
from tflearn.layers.conv import conv_2d
from tflearn.layers.normalization import local_response_normalization
from tflearn.layers.estimator import regression
from sklearn.cross_validation import train_test_split


def split_matrices_into_random_train_test_subsets():
    train = pd.read_csv(sys.stdin)
    train = np.array(train)
    train = permutation(train)
    X = train[:,1:785].astype(np.float32) 
    y = train[:,0].astype(np.float32)
    return train_test_split(X, y, test_size=0.33, random_state=42)

def reshape_data(Data,Labels):
    Data = Data.reshape(-1,28,28,1).astype(np.float32)
    Labels = (np.arange(10) == Labels[:,None]).astype(np.float32)
    return Data,Labels

X_train, X_test, y_train, y_test = split_matrices_into_random_train_test_subsets()

X_train,y_train = reshape_data(X_train,y_train)
X_test,y_test = reshape_data(X_test,y_test)
sys.stdout.flush() 
test_x = np.array(pd.read_csv(sys.stdin))
test_x = test_x.reshape(-1,28,28,1)
  
def Convolutional_neural_network():
    network  = input_data(shape=[None,28,28,1],name='input_layer')
    network  = conv_2d(network, nb_filter=6,  filter_size=6, strides=1, activation='relu', regularizer='L2')  
    network  = local_response_normalization(network)
    network  = conv_2d(network, nb_filter=12, filter_size=5, strides=2, activation='relu', regularizer='L2') 
    network  = local_response_normalization(network)
    network  = conv_2d(network, nb_filter=24, filter_size=4, strides=2, activation='relu', regularizer='L2')
    network  = local_response_normalization(network)    
 
    network = fully_connected(network, 128, activation='tanh')
    network = dropout(network, 0.8)
    network = fully_connected(network, 256, activation='tanh')
    network = dropout(network, 0.8) 
    network = fully_connected(network, 10, activation='softmax') 
    
    sgd   = tflearn.SGD(learning_rate=0.1,lr_decay=0.096,decay_step=100)
    top_k = tflearn.metrics.top_k(3) 
    
    network = regression(network, optimizer=sgd, metric=top_k, loss='categorical_crossentropy')
    return tflearn.DNN(network, tensorboard_dir='tf_CNN_board', tensorboard_verbose=3)
    
model = Convolutional_neural_network()
model.fit(X_train, y_train, batch_size=128, validation_set=(X_test,y_test), n_epoch=1, show_metric=True)

P = model.predict(test_x)

index = [i for i in range(1,len(P)+1)]
result = []
for i in range(len(P)):
    result.append(np.argmax(P[i]).astype(np.int))

res = pd.DataFrame({'ImageId':index,'Label':result})
print('%s\t' % (res))

My Python code works properly, I just want to run it on Hadoop ecosystem. When I ran command, I got it:
