ModuleNotFoundError: No module named 'tensorflow'

在 cmd:我的python版本是:

C:\Users\casper>python --version
Python 3.6.5 :: Anaconda, Inc.  

python 版本:

C:\Users\casper>conda --version
conda 4.5.4  

在 python 提示我像下面这样安装 Tensorflow:

conda create -n tensorflow python=3.6  
// CPU edition    
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow    

在 python 提示 :我的 Tensorflow 版本是:

(base) C:\Users\casper>activate tensorflow

(tensorflow) C:\Users\casper>python
Python 3.6.2 |Continuum Analytics, Inc.| (default, Jul 20 2017, 12:30:02) [MSC v.1900 64 bit (AMD64)] on win32

这真的是我第一次使用所有这些库和技术，我迷失了方向，我可以看到所有不同的 Python 版本，现在对我来说真的一团糟。我怎么能修好呢？

请记住更改为正确的内核。您可以在 Jupyter Notebook 中按 Kernel 执行此操作。 .然后选择Change kernel并选择您的内核。
