jupyter notebook中No module named 'tensorflow'

当我们在jupyter notebook中运行时可能会遇见没有某个包的情况，如下：

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-24005895b065> in <module>
      2 import h5py
      3 import matplotlib.pyplot as plt ----> 4 import tensorflow as tf 5 from tensorflow.python.framework import ops 6 import tf_utils ModuleNotFoundError: No module named 'tensorflow'

首先我的jupyter notebook是在本地设置的python3的环境deeplearning下运行的：

userdeMacBook-Pro:~ user$ conda activate deeplearning
(deeplearning) userdeMacBook-Pro:~ user$ jupyter notebook

但是很奇怪的是我python3的环境下已经安装好了tensorflow，但是jupyter中还是显示没有
