python3.8~3.12安装tensorflow-cpu

准备

创建并进入目录

mkdir tf-cpu
cd tf-cpu

编写测试代码

test_tensorflow.py

import tensorflow as tf
 
# 检查TensorFlow版本
print("\nTensorFlow version:", tf.__version__,end='\n\n')
 
# 创建一个简单的计算图并运行它
tensor = tf.constant([[1, 2], [3, 4]])
result = tf.multiply(tensor, 2)
 
# 启动默认的TensorFlow会话(自TensorFlow 2.x起,推荐使用tf.function和eager execution)
if hasattr(tf, 'Session'):  # TensorFlow 1.x风格
    with tf.Session() as sess:
        output = sess.run(result)
        print("Output of multiplication:", output)
else:  # TensorFlow 2.x风格,默认启用eager execution
    output = result.numpy()  # 将Tensor转换为NumPy数组以查看结果
    print("Output of multiplication:\n", output)
