Whenever I use ipython, hydrogen (atom) or jupyter notebook can't find any of the installed modules. I know I have pandas installed but the notebook says it's not found.
When I run the script normally (python script.py) it does import without any errors.
What can be the reason and solution?
Try the following:
pip3 install ipykernel --upgrade
python3 -m ipykernel install --user
Make sure that pandas is installed using pip3.
import pandas it threw the module not found error but when I importy numpy it did not throw me any error.
pip3 list to show the list of install packages and see if panda is on that list.pip3 install seems to have done the trick. Its strange because when i used pip install and conda install it says the package was already there. Is this something I need to fix or be worried about?pip install install python 2.x packages and pip3 install python 3.x.
I was having a similar issue. I installed a text processing tool using pip3. The installation was successful and I was able to run the test-code from the terminal, however I was unable to execute the same code from jupyter notebook. Checked that the sys.version was 3.7.1 in notebook but the terminal version was 3.6.9.
The problem was resolved after executing the following commands and relaunching the notebook:
pip3 install ipykernel --upgrade
python3 -m ipykernel install --user
I had the exact same problem on a newly installed virtual env. Turned out the problem was I was using an old version of pip and jupyter. The below did the trick for me:
$pip3 install pip --upgrade
$pip3 install jupyter --upgrade
For Anaconda/Jupyter Notebook:
Firstly go to your Anaconda Prompt.
Then activate your environment (or skip this if you want to do it in base)
pip3 install ipykernel --upgrade
Then put this code.
python -m ipykernel install --user --name torch --display-name "PyTorch (base)"
Here, torch = name of your virtual env (put anaconda-base for the base environment)
PyTorch (base) = display name you want to show in the kernel; replace it with your wish.
Then you will see the option to change the kernel (From Kernel Option) to your virtual environment you are looking for.

And if it is in VS Code, please check this answer. This solves it perfectly.
Look to the top right corner and click on the displayed Python version.
It should appear a list of your Python versions. Scroll down to the Python version you want to use and click on it.
After that you should see the Python version you selected in the top right corner.
The issue seems to be resolved by running pip3 install rather than pip install.
Something that worked for me, after hours looking for an answer was to delete the local Jupyter setting folder.

I had the same problem for my jupyter notebook. I installed the modules using the computers terminal and then when I tried loading them in my jupyter notebook, I couldn't load the modules but they were working just fine in the terminal.
At first, I checked the python versions and the terminal was running a python 3.8.5 version and the jupyter notebook was running 3.8.3, I thought this was the reason behind the problem and I updated the whole anaconda package but it still didn't work.
Then I opened the anaconda prompt and installed the package again and I saw that most of the package was already installed and said requirement satisfied but there was just one part that got installed in the anaconda prompt. (Note: I never uninstalled the package in any terminal, and just installed it again in the anaconda prompt). After installing it in the anaconda prompt, it started working just fine.
In summary, try and install the package again in the anaconda prompt.
pip install (module_name)
First, uninstall pip:
pip uninstall pip
then download get-pip.py:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
or use
wget https://bootstrap.pypa.io/get-pip.py
Finally run the script:
python get-pip.py
This will reinstall and install or upgrade pip to the latest version.
And that solved the problem.
The commands:
pip3 install ipykernel --upgrade
python3 -m ipykernel install --user
worked for me only after I re-installed pip (note I was having the issue for Python 3.7).
For that I did:
pip uninstall pip
then I used the (deprecated) command:
sudo easy_install pip
I also deleted any pip related thing in /usr/local/bin with the command:
rm -rf pip*
I had the same issue with other packages (scikit-commpy and ModulationPy).
import <package_name> was working on a script.py but not on a notebook.ipynb.
What worked for me:
To run %pip install <package_name> inside the notebook.
You only need to do it once (it will probably say "dependencies already installed" but afterwards it will solve the issue).
What didn't work for me but might be helpful:
sys.version from both script.py and notebook.ipynbhelp('modules') on both and compare
help('modules <package_name>') for filtering the long list to your specific package.
python --versionand show us the output. What I'm thinking is that you have two versions of python running on your machine. The terminal is running one and atom is running the other version.python --versionPython 3.6.5 :: Anaconda custom (x86_64). @amb1s1 this is what I get.import platformplatform.python_version()Let see what version Atom is using.
