I am trying to setup virtual environment for every deep learning project that i do locally on my laptop so that every package like numpy, matplotlib, opencv-python etc. i installed will be installed in that environment only not on my laptop globally. Now, the problem is i activate the virtual environment using source ENV_NAME/bin/activate and when i import libraries like cv2 in my notebook after installing cv2 in that environment setup, it says "
ModuleNotFoundError: No module named 'cv2'" please see the screenshots below. but when i deactivate that environment and install cv2 on my laptop globally and then try to import cv2, it works fine. Could someone please tell my why?
You need to restart the kernel in Jupyter Notebook for the new modules to show up.
Not sure if you already found the solution, but I stumbled upon this blog and it answers most questions of the type: I installed package X and now I can't import it in the notebook. Help!
You can install the package directly in the jupyter notebook using:
# Install a pip package in the current Jupyter kernel
import sys
!{sys.executable} -m pip install opencv-python
if using pip.
OR
# Install a conda package in the current Jupyter kernel
import sys
!conda install --yes --prefix {sys.prefix} opencv-python
if using conda.

I am trying to use tensorflow io to process mp3 audio files.
My operating system is Ubuntu 20.04.
I created a new dedicated virtual environnement and activated it using pyenv :
pyenv virtualenv testtfio; pyenv local testtfio
I also upgraded pip as I thought it might cause the issue. Then I installed tensorflow_io :
pip install tensorflow_io
This generates installation of this package and all dependencies as I can see after using "pip freeze".
Then when I try to import tensorflow_io it shows :
ModuleNotFoundError: No module named 'tensorflow_io'
What am I doing wrong ?
Thanks for your help
The issue was linked to Jupyter : I was using jupyter notebook in my new local environnement and it was running (I suppose from the pyenv global environment), but I forgot to install it in local virtualenv.
In order to solve the import issue in Jupyter notebook I just had to install Jupyter in my new local virtualenv.
pip install jupyter
I keep getting the error: ModuleNotFoundError: No module named 'seaborn'
when trying to import seaborn.
I have installed seaborn using both pip install seaborn and conda install seaborn.
I saw on seaborn that I am not the only one who has had this issue, but I have not been able to resolve this problem, how can I check and updated that my pip/conda points to the same installation as my interpreter?
EDIT:
I have tried running !pip install seaborn in the notebook, but this still does not work. I have also created my own conda env and installed seaborn (it shows base in the photos) but this also did not work.
you might have an old version of Jupyter notebook, so need to try this command to install it in the current kernel.
import sys
!{sys.executable} -m pip install seaborn
In the New Jupyter version (2019) can be installed simply as:
%pip install seaborn
Note: Answer from different question!
When I issue an Anaconda prompt conda search pytorch
then I get pytorch installed even issuing conda list command gives me:
pytorch 1.5.1 py3.7_cuda102_cudnn7_0 pytorch
But when I start python on command prompt and then issue import pytorch i get ModuleNotFoundError: No module named 'pytorch'.
Even I tried to do the same after issuing
conda create -n pytorch_env -c pytorch pytorch torchvision
conda activate pytorch_env
conda install -c pytorch pytorch torchvision
as written in Installing PyTorch via Conda but of no use. BTW does it require a restart of the machine after installing Anaconda? Also, let me know how I can use PyTorch in Jupyter notebooks.
Verify the installation with import torch not pytorch. Example code below, source.
from __future__ import print_function
import torch
x = torch.rand(5, 3)
print(x)
If above throws same issue in Jupyter Notebooks and if you already have GPU enabled, try restarting the Jupyter notebook server as sometimes it requires restarting, user reported.
when I tried to import this package from Jupyter notebook, I got following error message: ModuleNotFoundError: No module named 'torch'. Then, I tried installing Jupyter notebook application from Anaconda navigator for my environment(torch).
Restarted my Jupyter notebook and ran import torch and this time it worked
Otherwise, you need CPU only version of PyTorch.
conda install pytorch torchvision cpuonly -c pytorch
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

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:

I can import tensorflow on my computer:
>>> import tensorflow as tf
>>>
So I'm confused why this is another situation in notebook?
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
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 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.
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
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
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
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.
run this command which will install tensorflow inside conda
conda install -c conda-forge tensorflow
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

Once done I ran command
(tensorflow)C:>jupyter notebook
It opened new Juypter window and able to Run fine -
import tensorflow as tf
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"
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.
There are two ways to fix this issue.
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
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
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
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/
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
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.
