思路：

找一個 demo.py ，執行，檢驗

# 引入 tensorflow 模組 
import tensorflow as tf 
# 建立一個整型常量，即 0 階 Tensor
t0 = tf.constant(3, dtype=tf.int32) 
# 建立一個浮點數的一維陣列，即 1 階 Tensor
t1 = tf.constant([3., 4.1, 5.2], dtype=tf.float32) 
# 建立一個字串的2x2陣列，即 2 階 Tensor
t2 = tf.constant([['Apple', 'Orange'], ['Potato', 'Tomato']], dtype=tf.string) 
# 建立一個 2x3x1 陣列，即 3 階張量，資料型別預設為整型 
t3 = tf.constant([[[5], [6], [7]], [[4], [3], [2]]]) 
# 列印上面建立的幾個 Tensor 
print(t0)
print(t1)
print(t2)
print(t3)
 

執行 demo.py

問題#1 找不到指定模組？

D:\下載>
 

本地安裝

 pip install tensorflow-1.11.0-cp36-cp36m-win_amd64.whl 

完成後再次執行 demo.py

>>> 
==== RESTART: D:\下載\forGPU--CUDA--TensorFlow--CUDNN\tensorflow_demo_01.py ====
Tensor("Const:0", shape=(), dtype=int32)
Tensor("Const_1:0", shape=(3,), dtype=float32)
Tensor("Const_2:0", shape=(2, 2), dtype=string)
Tensor("Const_3:0", shape=(2, 3, 1), dtype=int32)
>>> 

嗯，這個表明 tensorflow 安裝成功了。

下個問題，如何檢驗 tensorflow-gpu 安裝成功了？
