No module named tensorflow in jupyter

I have some imports in my jupyter notebook and among them is 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:

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:

>>> import tensorflow as tf
>>>

So I'm confused why this is another situation in notebook?

I solve it by just updating Jupyter Notebook, So I think that the problem maybe using old version of Jupyter

solve it with pip:

pip install --upgrade jupyter

or with conda:

conda update jupyter

If you have installed TensorFlow globally then this issue should not be occurring. As you are saying you have installed it, maybe you did it in a virtual environment.

Some background:

By default, Jupyter will open with a global python interpreter kernel.

Possible solutions:

Change your jupyter notebook kernel to your virtual environment kernel. Please check here to see how to create a kernel out of your virtual environment.

Troubleshooting:

If the above solution dint work lets do some troubleshooting. When you add your new kernel to jupyter you might have got output like below

Installed kernelspec thesis-venv in C:\Users\vishnunaik\AppData\Roaming\jupyter\kernels\venv Check the file kernel.json in this path, which might look something like below

{
 "argv": [
  "C:\\Users\\vishnunaik\\Desktop\\Demo\\CodeBase\\venv\\Scripts\\python.exe",
   "-m",
   "ipykernel_launcher",
   "-f",
   "{connection_file}"
 ],
"display_name": "thesis-venv",
"language": "python",
"metadata": {
  "debugger": true
}

}

Check the path to the python.exe is rightly pointing to your virtual environment python version or not. If not then update it accordingly.

Now you should be able to use a virtual environment in your jupyter notebook. If your kernel takes a lot of time to respond see jupyter notebook server logs, sometimes you might get output like this

[I 21:58:38.444 NotebookApp] Kernel started: adbd5551-cca3-4dad-a93f-974d7d25d53b, name: thesis-venv C:\\Users\\vishnunaik\\Desktop\\Demo\\CodeBase\\venv\\Scripts\\python.exe: No module named ipykernel_launcher

This means your virtual environment doesnot have ipykernel installed. So install it in your virtual environment using below command.

pip install ipykernel

Now you have done everything possible, so I hope this will solve your issue.

TensorFlow package doesn't come by default with the root environment in Jupyter, to install it do the following :

  • Close Jupyter Notebook.
  • Open Anaconda Navigator (In windows : you can find it using the search bar)
  • On the sidebar, click on the Environments tab (by default you are using the root env).
  • You can see the installed packages, on the top switch to not-installed packages and search for tensorflow, if it doesn't show, click on Update index and it will be displayed.

The installation takes some time

Other supported libraries are necessary to install with TensorFlow.Make sure if these libraries are installed:

  • numpy
  • scipy
  • jupyter
  • matplolib
  • pillow
  • scikit-learn
  • tensorflow-addons,
  • tensorflow.contrib

This worked for me. I followed this: https://www.pythonpool.com/no-module-named-tensorflow-error-solved/

Run python -m ipykernel install --user --name <Environment_Name>. This should add your environment to the jupyter kernel list.

Change the kernel using Kernel->Change Kernel option or New-><Environment_Name>.

Note : Replace <Environment_Name> with the actual name of the environment.

As suggested by @Jörg, 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.

When I created TensorFlow virtual env, the spec had the entry for python which was pointing to base env. Thus by changing W:\\miniconda\\python.exe to W:\\miniconda\\envs\\tensorflow\\python.exe solved the problem.

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.

Probably there is a problem with the TensorFlow in your environment. In my case, After installing some libs, my TensorFlow stopped working.

So I installed TensorFlow again using pip. like so:

just run 

pip install tensorflow

then I re-imported it into my jupyter notebook as :

import tensorflow as ft

In case you want to install jupyter and base libs try this:

pip install jupyter tensorflow keras numpy scipy ipython pandas matplotlib sympy nose

Conda environment fetches the tensorflow package from the main system site-packages.

Step 1: Just deactivate conda environment 

conda deactivate  

pip install tensorflow

Step 2: Switch back to conda environment 

conda activate YOUR_ENV_NAME

jupyter notebook

Step 3: Run the cell with import tensorflow you should be able to import.

Thanks

There are two ways to fix this issue.

  1. The foremost way is to create a new virtual environment and install all dependencies like jupyter notebook, tensorflow etc.

conda install jupyter notebook

conda install -c conda-forge tensorflow

  1. The other way around is to install tensorflow in the current environment (base or any activated environment).

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:

https://conda.io/docs/user-guide/tasks/manage-environments.html

I had the same problem, and solved it by looking at the output of:

jupyter kernelspec list

which outputs the kernel information:

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.

So, to remove the Jupyter kernelspec, just use:

jupyter kernelspec remove python3

or jupyter kernelspec remove python2 if you're using python 2

Now, the output of jupyter kernelspec list should point to the correct kernel.

See https://github.com/jupyter/notebook/issues/397 for more information about this.

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

pip install jupyter

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 Prompt and 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. 

conda install -c conda-forge tensorflow

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:

 conda install -c conda-forge tensorflow

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"

This is what I did to fix this issue -

I installed tensorflow for windows by using below link -

https://www.tensorflow.org/install/install_windows

Once done - I activated tensorflow by using below command -

C:> activate tensorflow (tensorflow)C:> # Your prompt should change

Once done I ran below command -

(tensorflow)C:> conda install notebook

Fetching package metadata ........... Solving package specifications: .

Package plan for installation in environment

The following NEW packages will be INSTALLED:

If you installed a TensorFlow as it said in official documentation: https://www.tensorflow.org/versions/r0.10/get_started/os_setup.html#overview

I mean creating an environment called tensorflow and tested your installation in python, but TensorFlow can not be imported in jupyter, you have to install jupyter in your tensorflow environment too:

conda install jupyter notebook

After that I run a jupyter and it can import TensorFlow too:

jupyter notebook
