我在Python中有这个子代码,我无法理解它是什么或它做什么,尤其是这句话:
X[:,:,:,i]
子码是:
train_dict = sio.loadmat(train_location)
X = np.asarray(train_dict['X'])
X_train = []
for i in range(X.shape[3]):
X_train.append(X[:,:,:,i])
X_train = np.asarray(X_train)
Y_train = train_dict['y']
for i in range(len(Y_train)):
if Y_train[i]%10 == 0:
Y_train[i] = 0
Y_train = to_categorical(Y_train,10)
return (X_train,Y_train)
