When i try to use from IPython.display import clear_output, display_html, then i show the error:
(ImportError: No module named IPython)
I am using Python 2.7.13, and im trying to make the game of life from John Conway. I am following this link: http://nbviewer.jupyter.org/url/norvig.com/ipython/Life.ipynb
I have read another questions and answers about it, but any answer works for me. First, this error is showed in command line, and when i try to run this code in a file. Second, this error is direct to IPython, not submodule or something similiar.
Ok, finally i achieved my goal.
I wrote ipython --version but i found, it was not installed.
I tried to install it, with pip. I went to C:\Python27\Scripts, here is pip, you can try in this directory, or add to environment variables.
I tried to install ipython, but i found a error
error: Unable to find vcvarsall.bat
so i installed visual studio c++ 9.0, the version to python 2.7.
pip install ipython
If you scrolled this far you may want to try:
import IPython
as opposed to import Ipython. Notice that 2 letters are capitalized
For Anaconda try,
conda install -c anaconda ipython
Use this code to install the IPython library:
!pip install ipython
import IPython
Well, this works on Google Colab.
This is most likely because ipython is not installed.
You can install it with pip.
pip install ipython
If you are using Anaconda (the full version) ipython comes preinstalled. If you are using Miniconda or if the ipython is deleted for some reason you can re-install with
conda install -c anaconda ipython
If you are using it with jupyter. You might want to register the ipython with a user.
python -m ipykernel install [--user] [--name <machine-readable-name>] [--display-name <"User Friendly Name">]

I have a similar issue, but it appears when I was running the script under sudo. Fast and easiest way was to install IPython under sudo.
sudo pip3 install IPython
I am running a script that uses IPython module, in my terminal. If you are also trying to do something similar, this answer might help you.
!pip3 install IPython
Things to keep in mind:-
'I' and 'P' in IPython are uppercase.
I am running the above command in python 3.7.
you need to import
from IPython.display import Image
initially, I imported
from IPython.display import image
so there is Image not image
For me, the problem (that drove me crazy) is that I actually needed capitalization. The correct import after pip install is:
from IPython.display import display, update_display
etc.

I have used widely used packages(installed via pip) for a while in Jupyter notebook without any issues. I tried to do Python coding in VScode,but it somehow cannot load those packages.
I have tried changing python interpreter, but it did solve the issue. Does anyone know how to resolve this issue?
First make sure that you have the python interpreter installed on your computer. In your vscode UI you should see a terminal. You can install and upgrade pip through there if needed by using these commands:
pip install --upgrade pip
From here you should be able to import using pip commands.
Hi you can use terminal for installation.
otherwise you can anaconda iDE its very good tool and user friendly.
Did pip install pdfrw, uninstalled and reinstalled, restarted my laptop, but still unable to import the specified package as it returns error: No module named 'pdfrw'.
https://pypi.org/project/pdfrw/#pdfrw-philosophy
Any advice is appreciated.
Update: Tried installing by cmd, I'm using Jupyter Notebook as IDE :)
You have to make sure that the Python that you are using with Jupyter Notebook is the same that the one for which you are installing that package. If you have several Python interpreters installed or if you installed Ananconda to use Jupyter, you have to take care of which pip are you invoking from CMD.
If you are using Jupyter from Ananconda, try to install the package using conda.
conda install pdfrw
Another thing that you can do is open a Command Prompt and type:
where python
you will get the path to the interpreters that you have installed. In my case I get:
>>> C:\Windows\system32>where python
C:\Python39\python.exe
C:\Python38\python.exe
>>> C:\Windows\system32>where pip
C:\Python39\Scripts\pip.exe
C:\Python38\Scripts\pip.exe
Then you can use a concrete interpreter to call pip, in my case I will do:
C:\Python39\python.exe -m pip install pdfrw
After the installation finish, invoke the same interpreter you use to call pip:
C:\Python39\python.exe
Then try to import pdfrw. If you can import it, then the problem is that you are using a different interpreter in Jupyter Notebook.
I am trying to run jupyter notebook and getting following error. I am using Win 7 with anaconda python 3.7.
ImportError: Something is wrong with the numpy installation. While
importing we detected an older version of numpy in
['C:\Users\shaher11\Anaconda3\lib\site-packages\numpy']. One
method of fixing this is to repeatedly uninstall numpy until none is
found, then reinstall this version.
i think it is the same problem that mentioned here
I had a similar problem on python 3.6 (which I have to use for Keras) and reinstalling using "conda remove numpy" and "conda install numpy" didn't do the trick.
What worked was using pip3 instead. i.e. "pip 3 install numpy"
I think conda was trying to install the wrong version of numpy for the python version. Might be worth a try for your python 3.7 issue.
"conda update --all" worked for me.
Also, for anyone trying this on Jupyter using GCP, open a terminal in Jupyter itself and run that command to get it to work.
This works in Python 3.6:
conda install -c conda-forge numpy==1.19.5. Neither pip install or pip3 install was able to resolve the ImportError in my case.
I have recently installed Anaconda with Python 3.5 and all the rest. I come from R where I am used to install packages dynamically. I am trying to install a module called scitools through jupyter notebook. I would like to recreate this in jupyter. However, I don't know how to dynamically install packages (if it's possible). I would greatly appreciate your help. Thank you!
EDIT: I am trying to use conda as recommended by the community, but it's not working. I am using mac OSX
Check Jake Vander Plus Blog here to learn how to install a package with pip from Jupyter Notebook.
# Install a pip package in the current Jupyter kernel
import sys
!{sys.executable} -m pip install numpy
So if you have already done the install with anaconda, you may already have the module installed. In that case in your jupyter notebook after you have activated your kernel, you just need to make sure you execute the import statement.
import scitools
If you haven't installed that module yet, you can install it one of two ways. Both work from your command line or terminal.
pip install scitools
or since you have Anaconda
conda install scitools
and that should do it. Your import statement in your notebook when executed should correctly locate and enable the use of that module.
I had the same issue. It turns out if you open an anaconda window, which in Windows is accessible under the Anaconda drop down, it points to the correct location to install (or update) using pip.
I wonder if it's possible to install python packages without leaving the IPython shell.
See the accepted answer from #Chronial which is the best way to do this in modern ipython or jupyter (as of 2018) is to use the %pip magic:
%pip install my_package
The answer below from 2011 is now outdated: See the accepted answer for an easier way to do this in modern jupyter.
You can use the ! prefix like this:
!pip install packagename
The ! prefix is a short-hand for the %sc command to run a shell command.
You can also use the !! prefix which is a short-hand for the %sx command to execute a shell command and capture its output (saved into the _ variable by default).
This answer is outdated: See the accepted answer for an easier way to this in modern jupyter.
aculich's answer will not work in all circumstances, for example:
If you installed ipython/jupyter in a venv and run it directly via the venv's python binary
If you have multiple python versions, like EntryLevelR.
The correct command is:
import sys
!{sys.executable} -m pip install requests
The best way to do this in modern ipython or jupyter is to use the %pip magic:
%pip install my_package
import pip
pip.main(['install', 'package_name'])
The above shell-based answers don't work unless pip is in your $PATH (e.g. on Windows).
I like hurfdurf's answer, but on its own iPython may not recognize the new module (especially if it adds to the library path). Here's an augmented example with iPython 3:
import pip
pip.main(['install','pygame'])
# import pygame at this point can report ImportError: No module named 'pygame'
import site
site.main()
# now with refreshed module path...
import pygame
In case you are using Conda Package Manager, the following syntax might fit your needs
$ conda install -c conda-forge <targetPackageName>
https://pypi.org/project/earthpy/
!pip install packagename or similar codes will not be the true answer if we have various python versions, where the desired python version is not the system default one. Such codes will install packages on the system default python version only. From my opinion, the following code would be helpful:
import pip
if int(pip.__version__.split('.')[0])>9:
from pip._internal import main
else:
from pip import main
main(['install', 'package_name']) # the strings in the square brackets could be specified as needed
This code is written based on pip version, which can be run from within the console and will be applied on any python versions which path is set by the console; This python version specs could be seen by import sys; sys.version, sys.path. I'm not sure this is the best approach, but the aforementioned code worked for my purposes and !pip install packagename or %pip install packagename did not (where python: 2.7.9, pip: 19.2.3, IPython QtConsole: 3.1.0).
