在Jupyter Notebook中导入TensorFlow时遇到麻烦，但在bash中运行良好

Question

我在没有安装anaconda的情况下通过“使用本机pip安装”安装了张量流，并且能够在从Terminal启动的Python控制台中导入TensorFlow。 图片

但是我在Jupiter Notebook中运行了相同的代码，结果显示出来。 图片

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

----> 1 import tensorflow as tf
      2 hello = tf.constant('Hello, TensorFlow!')
      3 sess = tf.Session()
      4 print(sess.run(hello))

ImportError: No module named tensorflow

我该如何解决这个问题？

Python，Tensorflow和Jupyter要么必须处于保存版本python2 / python3。 以下是使用python3设置jupyter和Tensorflow的命令

sudo apt install python3-pip
pip3 install --upgrade pip   ##optional
pip3 install jupyter


##Install Tensorflow
pip3 install --upgrade tensorflow

Test
$ python3

##Launch jupyter
jupyter notebook   
(In Ubuntu you may need to launch ~/.local/bin/jupyter-notebook until you relaunch the bash i.e. PATH issue)
##Create new notepad and run
import tensorflow as tf
