Question

我正在Mac上执行MNIST手指识别任务，但它没有显示图像的预测值，而只是进行了准确的检查。

我在Mac上使用Spyder。它似乎在Windows上可以正常工作，但在我的Mac上却不能。顺便说一句，我正在使用python（spyder）3.7。

import tensorflow as tf
import numpy as np
from matplotlib import pyplot as plt

mnist = tf.keras.datasets.mnist

(x_train, y_train),(x_test, y_test) = mnist.load_data() 
x_train, x_test = x_train / 255.0, x_test / 255.0

model = tf.keras.models.Sequential([tf.keras.layers.Flatten(input_shape=(28, 28)), 
                                    tf.keras.layers.Dense(512, activation=tf.nn.relu), 
                                    tf.keras.layers.Dropout(0.2),
                                    tf.keras.layers.Dense(10, activation=tf.nn.softmax)])

model.compile(optimizer='adam',loss='sparse_categorical_crossentropy',metrics=['accuracy']) 
model.fit(x_train, y_train, epochs=1)
model.evaluate(x_test, y_test)

x_pred_value = np.argmax(model.predict(x_test),axis=1)

for i in range(7):
    print("\nThe following digit is a ",x_pred_value[i]) 
    plt.imshow(x_test[i])
plt.show()

我希望代码能给我输出照片并使用以下行给出预测：“以下输出为...”

此外，这些是我收到的警告消息：

在Mac上的MNIST手写数字识别任务，但不输出手写数字的照片
