jupyter notebook中No module named 'tensorflow'

當我們在jupyter notebook中運行時可能會遇見沒有某個包的情況，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是在本地設置的python3的環境deeplearning下運行的：

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

但是很奇怪的是我python3的環境下已經安裝好了tensorflow，但是jupyter中還是顯示沒有

(deeplearning) userdeMBP:~ user$ python
Python 3.7.2 (default, Dec 29 2018, 00:00:04) [Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import tensorflow >>> tensorflow.__version__ '1.13.1' >>> 

可見安裝了1.13.1版本的tensorflow

 

解決方法有：

打開你的anaconda navigator，按下圖選擇，之后apply安裝就行:

 報了個錯：

UnsatisfiableError: The following specifications were found to be in conflic
pytorch
tensorflow == 1.11.0
use conda info <package> to check dependencies

使用conda info tensorflow查看依賴后，發現tensorflow <= 1.12.0版本不支持python3.7，而anaconda navigator中提供的tensorflow的最高版本是1.12.0，所以我就將其降到了3.6版本，即在指定的環境deeplearning下運行：

(deeplearning) userdeMBP:~ user$ conda install python=3.6

 當然這樣可能會導致一些之前安裝的包的丟失,因為再import tensorflow時可見之前安裝的tensorflow沒了：

(deeplearning) userdeMBP:~ user$ python
Python 3.6.8 |Anaconda, Inc.| (default, Dec 29 2018, 19:04:46) 
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'

 

然后再安裝就可以看見安裝成功：

然后再查看：

(deeplearning) userdeMBP:~ user$ python
Python 3.6.8 |Anaconda, Inc.| (default, Dec 29 2018, 19:04:46) 
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow
>>> tensorflow.__version__
'1.12.0'
>>> 

可見相應的環境deeplearning中成功安裝了tensorflow == 1.12.0版本

 

⚠️

如果在過程中還是有UnsatisfiableError的錯，除了依賴的問題，還可以試試：

userdeMBP:~ user$ conda update conda

更新conda
