No module named tensorflow in jupyter
提问by Skotti Bendler
I have some imports in my jupyter notebook and among them is tensorflow:
我的 jupyter 笔记本中有一些导入，其中包括 tensorflow：
ImportError Traceback (most recent call last)
<ipython-input-2-482704985f85> in <module>()
4 import numpy as np
5 import six.moves.copyreg as copyreg
----> 6 import tensorflow as tf
7 from six.moves import cPickle as pickle
8 from six.moves import range
ImportError: No module named tensorflow
I have it on my computer, in a special enviroment and all connected stuff also:
我在我的电脑上有它，在一个特殊的环境和所有连接的东西中：
Requirement already satisfied (use --upgrade to upgrade): tensorflow in /Users/mac/anaconda/envs/tensorflow/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): six>=1.10.0 in /Users/mac/anaconda/envs/tensorflow/lib/python2.7/site-packages (from tensorflow)
Requirement already satisfied (use --upgrade to upgrade): protobuf==3.0.0b2 in /Users/mac/anaconda/envs/tensorflow/lib/python2.7/site-packages (from tensorflow)
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.10.1 in /Users/mac/anaconda/envs/tensorflow/lib/python2.7/site-packages (from tensorflow)
Requirement already satisfied (use --upgrade to upgrade): wheel in /Users/mac/anaconda/envs/tensorflow/lib/python2.7/site-packages (from tensorflow)
Requirement already satisfied (use --upgrade to upgrade): setuptools in ./setuptools-23.0.0-py2.7.egg (from protobuf==3.0.0b2->tensorflow)
I can import tensorflow on my computer:
我可以在我的电脑上导入 tensorflow：
>>> import tensorflow as tf
>>>
So I'm confused why this is another situation in notebook?
所以我很困惑为什么这是笔记本中的另一种情况？

If you installed a TensorFlow as it said in official documentation: https://www.tensorflow.org/versions/r0.10/get_started/os_setup.html#overview
如果您按照官方文档中的说明安装了 TensorFlow：https: //www.tensorflow.org/versions/r0.10/get_started/os_setup.html#overview
I mean creating an environment called tensorflowand tested your installation in python, but TensorFlow can not be imported in jupyter, you have to install jupyter in your tensorflow environment too:
我的意思是创建一个名为tensorflow的环境并在 python 中测试你的安装，但是 TensorFlow 不能在 jupyter 中导入，你也必须在你的 tensorflow 环境中安装 jupyter：
conda install jupyter notebook
After that I run a jupyter and it can import TensorFlow too:
之后我运行了一个 jupyter，它也可以导入 TensorFlow：
jupyter notebook

Jupyter runs under the conda environment where as your tensorflow install lives outside conda. In order to install tensorflow under the conda virtual environment run the following command in your terminal:
Jupyter 在 conda 环境下运行，因为您的 tensorflow 安装位于 conda 之外。为了在 conda 虚拟环境下安装 tensorflow，请在终端中运行以下命令：
conda install -c conda-forge tensorflow

I had the same problem, and solved it by looking at the output of:
我遇到了同样的问题，并通过查看以下输出解决了它：
jupyter kernelspec list
jupyter kernelspec list
which outputs the kernel information:
输出内核信息：
python2 /Users/Username/Library/Jupyter/kernels/python2
python3 /Users/Username/Library/Jupyter/kernels/python3
Notice that the path points to the Jupyter kernel for the user. To use it within the the Anaconda environment, it needs to point to the conda env you are using, and look something like Anaconda3\envs\Env_Name\share\jupyter\kernels\python3.
请注意，该路径指向用户的 Jupyter 内核。要在 Anaconda 环境中使用它，它需要指向您正在使用的 conda env，并且看起来像Anaconda3\envs\Env_Name\share\jupyter\kernels\python3.
So, to remove the Jupyter kernelspec, just use:
因此，要删除 Jupyter 内核规范，只需使用：
jupyter kernelspec remove python3
jupyter kernelspec remove python3
or jupyter kernelspec remove python2if you're using python 2
或者jupyter kernelspec remove python2如果您使用的是 python 2
Now, the output of jupyter kernelspec listshould point to the correct kernel.
现在，输出jupyter kernelspec list应该指向正确的内核。

回答by Kelemu
the problem may when the Jupyter notebook may launching from the default but for able to import tensorflow and keras libraries so you have to install jupyter notebook like what you have installed the libraries
当 Jupyter Notebook 可能从默认启动但能够导入 tensorflow 和 keras 库时，问题可能会出现，因此您必须像安装库一样安装 jupyter notebook
pip install jupyter

I was able to load tensorflow in Jupyter notebook on Windows by: first do conda create tensorflow install, then activate tensorflow at the command prompt , then execute "Jupyter notebook" from command line. Tensorflow imports at the notebook with no error. However, I was unable to import "Pandas" &"Matplotlib, ....etc"
我能够通过以下方式在 Windows 上的 Jupyter notebook 中加载 tensorflow：首先执行 conda create tensorflow install，然后在命令提示符下激活 tensorflow，然后从命令行执行“Jupyter notebook”。Tensorflow 在笔记本上导入，没有错误。但是，我无法导入“Pandas”和“Matplotlib, ....etc”

I also had the same problem for a long time. I wanted to import tensorflow inside the jupyter notebook within windows 10. I followed all the instructions and commands that were suggested and it was not working from the command prompt. Finally, I tried this command with the Anaconda Promptand it worked successfully. If you are using jupyter notebook within Anaconda then go goto the windows search terminal and type "Anaconda Prompt" and inside it type following command, It will install the tensorflow inside the jupyter notebook.
我也有同样的问题很长一段时间。我想在 Windows 10 中的 jupyter notebook 中导入 tensorflow。我遵循了所有建议的说明和命令，但它在命令提示符下不起作用。最后，我在Anaconda Prompt 上尝试了这个命令并且成功了。如果您在 Anaconda 中使用 jupyter notebook，则转到 Windows 搜索终端并键入“Anaconda Prompt”，然后在其中键入以下命令，它将在 jupyter notebook 中安装 tensorflow。
conda install -c conda-forge tensorflow

As suggested by @J?rg, if you have more than one kernel spec. You have to see the path it points to. In my case, it is actually the path that was to be corrected.
正如@J?rg 所建议的，如果您有多个内核规范。你必须看到它指向的路径。就我而言，它实际上是要更正的路径。
When I created TensorFlowvirtual env, the spec had the entry for python which was pointing to baseenv. Thus by changing W:\\miniconda\\python.exeto W:\\miniconda\\envs\\tensorflow\\python.exesolved the problem.
当我创建TensorFlow虚拟 env 时，规范中有指向baseenv 的python 条目。从而通过改变W:\\miniconda\\python.exe来W:\\miniconda\\envs\\tensorflow\\python.exe解决问题。
So it is worth looking at your kernel spec. Delete that is not needed and keep those you want. Then look inside the JSON files where the path is given and change if needs be. I hope it helps.
因此，值得查看您的内核规范。删除不需要的，保留你想要的。然后查看给出路径的 JSON 文件，并根据需要进行更改。我希望它有帮助。

There are two ways to fix this issue.
有两种方法可以解决此问题。
- The foremost way is to create a new virtual environment and install all dependencies like jupyter notebook, tensorflowetc.
- 最重要的方法是创建一个新的虚拟环境并安装所有依赖项，如jupyter notebook、tensorflow等。
conda install jupyter notebook
conda install jupyter notebook
conda install -c conda-forge tensorflow
conda install -c conda-forge tensorflow
- The other way around is to install tensorflow in the current environment (base or any activated environment).
- 另一种方法是在当前环境（基础或任何激活的环境）中安装 tensorflow。
conda install -c conda-forge tensorflow
conda install -c conda-forge tensorflow
Note:It is advisable to create a new virtual environment for every new project. The details how to create and manage virtual environment using conda can be find here:
注意：建议为每个新项目创建一个新的虚拟环境。可以在此处找到如何使用 conda 创建和管理虚拟环境的详细信息：

Conda environment fetches the tensorflow package from the main system site-packages.
Conda 环境从主系统站点包中获取 tensorflow 包。
Step 1: Just deactivate conda environment
第 1 步：只需停用 conda 环境
conda deactivate
pip install tensorflow
Step 2: Switch back to conda environment
第 2 步：切换回 conda 环境
conda activate YOUR_ENV_NAME
jupyter notebook
Step 3: Run the cell with import tensorflowyou should be able to import.
第 3 步：运行单元格，import tensorflow您应该可以导入。
Thanks
谢谢
