I have tried to install jupyter lab on my Kubuntu machine.
If I install jupyter lab with 'pip3 install jupyter jupyterlab' the command 'jupyter notebook' works completly fine. But if I try to run 'jupyter lab' every time I get the message:
Traceback (most recent call last):
File "/usr/local/bin/jupyter", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python3.6/dist-packages/jupyter_core/command.py", line 230, in main
command = _jupyter_abspath(subcommand)
File "/usr/local/lib/python3.6/dist-packages/jupyter_core/command.py", line 133, in _jupyter_abspath
'Jupyter command `{}` not found.'.format(jupyter_subcommand)
Exception: Jupyter command `jupyter-lab` not found.
What is wrong?
I tried to reinstall jupyter and jupyterlab multiple times with the same issue.
Its the space. Its always the space. Never ever use spaces within package name. Its always either namepart1-namepart2 or namepart1namepart2. This is because arguments are separated by space. So if you put space in between, it makes pip think that you want to install two different packages named jupyter and lab. Just use:
python -m pip install jupyterlab
Or simply:
pip install jupyterlab
No need to uninstall or reinstall anything. However to run jupyter lab server you might want to add spaces as follows:
jupyter lab
In my case, the only way to fix this was to add the following directory to the PATH in Linux:
/home/ubuntu/.local/bin
When installing jupyterlab, we may get warning like this:
Installing collected packages: jupyterlab
WARNING: The scripts jlpm, jupyter-lab, jupyter-labextension and jupyter-labhub are installed in '/home/tln/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed jupyterlab-3.0.14
So as per this warning, scripts like jupyter-lab will be unavailable unless added to the PATH.
Use below command to add these scripts to be able to use from command line:
tln#tln-X550LD:~$ export PATH="$HOME/.local/bin:$PATH"
That's it. This worked fine for me.
I had the same error on Windows 10. It was with pip install jupyterlab. Then after the error I uninstalled it with pip and reinstalled with "pip install jupyterlab". Everything worked flawlessly thereafter.
In your case you're using pip3. Try it as above or see if pip3 needs an update.
I had same issue. I solved it running pip install jupyterlab in prompt with admin privilegies.
Had the same issue and resolved it by installing with pip3
pip3 install jupyterlab;
jupyter lab
If you face -bash: jupyter-lab: command not found or -bash: jupyter: command not found, etc., you can look for "jupyter-lab" and enter that full path instead.
Mac:
$ /Users/mark/venv/bin/jupyter-lab
Windows:
C:\mark\venv\Scripts\jupyter-lab.exe
I got this same error every time I forgot to activate the virtualenv jupyterlab was installed into. After activating the virtualenv, all's well.
With pip
$ source [path_to_venv]/bin/activate
With pipenv
$ pipenv shell
Then, with a prompt indicating an activated shell, you can enter your command
(venv) $ jupyter lab
With conda or other more holistic python environments, you probably use their gui to activate a virtualenv with jupyter and jupyterlab installed.
Install with Anaconda
conda install -c conda-forge notebook
conda install -c conda-forge jupyter
conda install -c conda-forge jupyter_contrib_nbextensions
Once installed you just have to run
pip install jupyterlab
~/.local/bin/jupyter-lab
and ready and open browser http://localhost:8888/lab
Ubuntu 22
Lubuntu 22
well the problem is like this:
the jupyterlab module has not been packaged for debian, but the jupyterlab_server package has, named python3-jupyterlab-server.
please sudo apt install python3-jupyterlab-server.
then, as your user, run pip3 install jupyterlab, that will install it in your ~/.local/bin a few programs, the missing jupyter-lab among them.
last, but not least, run jupyter-serverextension enable --py jupyterlab.
to be able to run jupyter lab, you first need to run export PATH="/home/$(whoami)/.local/bin:"$PATH. this command will run automatically if added to your ~/.bash_profile.
ubuntu can not find the jupyter-lab because it is not in path.
in order to check the place of installment. run below command
find ~ -name jupyter-lab
possible result: /home/soshiant/.local/bin/jupyter-lab
for adding a directory to the Linux path you can follow below link:
How to add a directory to the PATH
if anyone still struggling ...
try:
find ~ -name jupyter-lab
and then:
export PATH=[path]
then try again: jupyter lab
note:
don't add any extra spaces and PATH is case sensitive and if u still struggling just try to install any missing pkgs after hosting to the main path by opining another tab or changing the path to main.
and then host to localhost:8888/lab
that should works fine...
I was using conda to install
conda install -c conda-forge jupyterlab
and this error came about.
I simply used this command to get it to run.
pip install jupyterlab
In my ubuntu installation this was qused by not using sudo before the install.
sudo pip install jupyterlab
If you already installed jupyterlab, and it dit not work, you can install again using sudo, you dont need to remove the old version first for it to work

I could use some clarification regarding anaconda envs and the installed packages. I have just began using environments other than the base to keep my installations clean.
I just deleted my anaconda3 folder, installed it from scratch, made a new environment and tried to run a jupyter-notebook.
When reading excel via pandas I get the error Missing optional dependency 'xlrd'
prompting me to install xlrd via conda or pip.
So I open the terminal, activate the env I’m working in and install it using conda. I close the JN from the terminal, reopen it and run the same code. The problem persists.
I repeat the procedure, this time indicating the name of the env at the end. Problem persists.
I checked which python in the terminal, it is indeed the anaconda3/envs/newenv/bin/python
I do the same (in the new env) using pip. I use the command .../anaconda3/envs/newenv/bin/python -m pip install xlrd. I get the message Requirement already satisfied: xlrd in ./anaconda3/envs/newenv/lib/python3.7/site-packages (1.2.0).
I even tried installing the package inside the notebook using !conda install xlrd, still I get the same error.
Finally, I open Jupyter via the base env, and the package works there perfectly.
I have no idea why I can’t install this under the newenv, which was the point of having local envs after all.
Thanks heaps for your help!
You need to install the kernel in Jupyter to be able to use it.
jupyter kernelspec list
That command will give you the list of kernels you have. I am assuming it only shows you Python3
You will now need to install a kernel. Remember to do this while inside your virtual environment
python3 -m pip install ipykernel
python3 -m ipykernel install --user --name <your-new-kernel-name>
You should now see this in Jupyter notebook. Select the kernel in Jupyter and you should be good to go.
Another thing you may want to try is to install Jupyter while inside your virtual environment. While inside your virtual environment, you could do:
python3 -m pip install jupyter lab
and then while still inside your virtual environment, run jupyter after checking which jupyter. It should solve your problem as well.
after restart my ubuntu 16.04, could not find pip
I can only get my original pip via python3 -m pip freeze
if I use pip freeze there shows bash: /usr/bin/pip: No such file or directory
And I installed my jupyter via pip install and I could not use jupyter notebook command now. It shows jupyter: command not found
And I make sure I use sudo apt-get update and when I want to install a new jupyter with sudo apt-get install jupyter-notebook it shows
E: Unable to locate package jupyter-notebook
Seems several system configuration go wrong? How to recover these? How can I open my jupyter?
bash: /usr/bin/pip: No such file or directory
Verify the file /usr/bin/pip exists. If it does check the first line:
head -1 /usr/bin/pip
The line (called shebang) must be something like #!/usr/bin/python. If it isn't edit the file and fix the shebang line to point to an existing python binary.
I installed my jupyter via pip install and I could not use jupyter notebook command now. It shows jupyter: command not found
It's because pip installed jupyter into a directory not in $PATH. Most probably /usr/local/bin/. Check the directory with pip show --files jupyter and add the directory to your $PATH both in the current shell and in your ~/.bash_profile.
I want to install a new jupyter with sudo apt-get install jupyter-notebook it shows E: Unable to locate package jupyter-notebook
Try sudo apt-get update.
The pip problem has been solved.
The reason is that PATH is somehow modified and it loses the ~/.local/bin, the original pip is in this path and pip also install jupyter notebook in this path.
After I added ~/.local/bin to PATH I can run pip and jupyter notebook, in brief this is a path problem
I have installed a created a virtualenv machinelearn and installed a few python modules (pandas, scipy and sklearn) in that environment.
When I run jupyter notebook, I can import pandas and scipy in my notebooks - however, when I try to import sklearn, I get the following error message:
import sklearn
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-8fd979e02004> in <module>()
----> 1 import sklearn
ImportError: No module named 'sklearn'
I am able to import all modules, at the command line - so I know they have been successfully installed:
(machinelearn) me#yourbox:~/path/to/machinelearn$ python -c "import pandas, scipy, sklearn"
(machinelearn) me#yourbox:~/path/to/machinelearn$
How can I import sklearn in my jupyter notebook running in a virtualenv?
You probably have not installed jupyter / IPython in your virtualenv. Try the following:
python -c "import IPython"
and check that the jupyter command found in your $PATH is the one from the bin folder of your venv:
which jupyter
For windows users in a powershell console, you can use the following to check that the jupyter command in your $env:Path is the one from the Scripts folder of you venv:
get-command jupyter
Edit: if this is the problem, just run python -m pip install jupyter in your venv.
Edit 2: actually you might also need:
python -m ipykernel install --user --name=my-virtualenv-name
and then switch the kernel named "my-virtualenv-name" in the jupyter user interface.
Edit 3: maybe the --user flag in the last command is a bad idea:
python -m ipykernel install --name=my-virtualenv-name
Another approach to take is to have one global jupyter installation, but to point to different kernels to run as the backend.
That approach is outlined here in their docs:
http://help.pythonanywhere.com/pages/IPythonNotebookVirtualenvs
Copying below in case the link breaks:
You can use a virtualenv for your IPython notebook. Follow the following steps:
Install the ipython kernel module into your virtualenv
workon my-virtualenv-name # activate your virtualenv, if you haven't already
pip install ipykernel
Now run the kernel "self-install" script:
python -m ipykernel install --user --name=my-virtualenv-name
Replacing the --name parameter as appropriate.
You should now be able to see your kernel in the IPython notebook menu: Kernel -> Change kernel and be able so switch to it (you may need to refresh the page before it appears in the list). IPython will remember which kernel to use for that notebook from then on.
To use Jupyter notebook with virtual environment (using virtualenvwrapper) plus packages installed in that environment, follow steps below:
create a virtual environment
mkvirtualenv --no-site-packages --python=/your/python/path your_env_name
Activate the virtual environment
workon your_env_name
Install Jupyter and other packages
pip install jupyter, numpy
Add a new kernel to your Jupyter config
ipython kernel install --user --name=your_env_name
Done. You may now use Jupyter notebook under the virtual environment.
jupyter-notebook
Disclaimer: the question has been answered but is hidden in one of the replies. I googled and took sometime to find the right answer. So I just summarize it so someone having the same issue can easily follow.
Assuming that jupyter is installed on your machine, not on the virtual environtment.
Using a virtual environment with Jupyter notebook
VENV_NAME = "YOUR VIRTUAL ENV NAME"
1) virtualenv VENV_NAME
2) source venv/bin/activate
3) Add this package if not present: pip3 install ipykernel
4) Then execute this command: ipython kernel install --user --name=VENV_NAME
5) Now open up the Jupyter Notebook and in change kernel select VENV_NAME
6) To install a new package perform pip3 install <PACKAGE NAME> in your terminal and repeat step 4.
Hope it helps!
Solution without adding a new kernel globally!!
create a new virtual environment by
python3 -m virtualenv envname
Activate your enviroment and install jupyter in it by
pip install jupyter
One thing you have to make sure before installing jupyter is that you don't have following packages already installed in it.
ipykernel
ipython
ipython-genutils
ipywidgets
jupyter
jupyter-client
jupyter-console
jupyter-core
If you've previously installed them then first uninstall them by pip uninstall.
Install your desired packages in activated virtualenv and launch jupyter in it and voila!
Creation of virtualenv with python3 -m venv command
I had the same problem as yours.
In my case I had created the virtualenv with the command
python3 -m venv ./my_virtual_env --system-site-packages
The problem was I could not install jupyter inside the virtual environment as it was already in the system-site-package (when you try to install it, it tells you "Requirement already satisfied").
To install jupyter, (and in a first instance pip, that does not get installed neither in your virtual environment with this command) but still have access to system-site-package you can run :
python3 -m venv ./my_virtual_env
Activate you virtual environment, run pip3 install jupyter (and pip3 install pip) and then turn on the option include-system-site-packages in the file ./my_virtual_env/pyvenv.cfg.
After deactivation and reactivation of you environment, you will have access to system site-packages.
Creation of virtualenv with virtualenv command
Given this answer you can prevent the access to system site-packages by creating a file ./my_virtual_env/lib/python3.4/no-global-site-packages.txt,
and get the access back by removing it.
You can still install jupyter inside your virtual-environment if you have created your virtual env using:
python -m venv --system-site-packages path/to/my-venv
Simply do this:
activate-your-env
pip install -I jupyter
And you are now ready to go
jupyter notebook
I am using the Jupyter notebook with Python 3 selected. On the first line of a cell I am entering:
import pandas as pd
The error I get from the notebook is, ImportError: No module named 'pandas'. How can I install pandas to the jupyter notebook? The computer I launched the Jupyter notebook from definitely has pandas.
I tried doing:
!pip install pandas
And it says it is already installed but for Python 2.7 at the bottom. My script shows it is a Python 3 script at the top though.
When I do echo $PATH in Ubuntu is shows that '/home/user/anaconda2/bin' is on the first entry. I think I may need to change this to be anaconda3?
UPDATE: When I try and launch a Python3 script through jupyter the command line which launched Jupyter gives me the error "ImportError: No module named 'IPython.paths'. Then there is a timeout waiting for 'kernel_info' reply. Additionally, I tried removing anaconda but still experience the same error. I have tried to make so many quick fixes now, that I am not sure what the next step is to get this working.
As your default python version is 2.x , if you don't have any emphasis on the python 3.x you can try from the first by the below scripts.
pip install --upgrade pip
pip install jupyter
then in jupyter notebook:
!pip install pandas
The version of notebook will be 2.x.
Otherwise install pip3 by the below Linux commands.
sudo apt-get install python3-setuptools
sudo easy_install3 pip
now you can add pandas to the notebook by !pip3 install pandas.
This worked for me
in Jupiter notebook
import sys
print(sys.executable)
copy path eg:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
install the module on the terminal like this.
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3 -m pip install pandas
Or it can be installed directly from Jupyter Cell as follows
! /Library/Frameworks/Python.framework/Versions/3.7/bin/python3 -m pip install pandas
If you use anaconda already as a distribution, stop using pip in that context. Use conda instead and you will stop having headaches. The command lines and procedures for setting up a new environment are pretty well documented here.
Basically upgrading python or having specific branches:
conda update python
conda install python=3.5
Or using specific environments:
conda create -n py35 python=3.5 anaconda
simple step to resolve the problem is
( NOTE: Remember what you have selected python 2 or python 3).
for python 2+
!pip install pandas
or if you have user permission error type
!pip install pandas --user
for python 3+
!pip3 install pandas
or if you have user permission error type
!pip3 install pandas --user
If pip3 is install you could run
!pip3 install pandas
This is what i have done in my system:
I have installed both anaconda for python 2.7 and anaconda for python 3.5. Anaconda helps keep both the environment separate.
In Ubuntu:
The directory structure is like this:
anaconda2/bin/
anaconda3/bin/
Whenever i want to use python 2.7 i go to anaconda2/bin/ and create an environment or activate already existing environment and install or import all the necessary packages and same goes for python3.5 (go to anconda3/bin/ create or activate the required environment). This helps me keep things separate.
Since you are using anaconda you should first use "conda install " if that package is not found, then you can use pip install .
In Windows:
If you install both anaconda2 and anaconda3, its quite easy..
the shortcuts for anaconda prompt are in C:\Users\your-username\
there will be two folders anconda2 and anaconda3, you can start conda prompt for python2.7 from anaconda2 and python3.5 from anconda3
So, once you start the anaconda prompt you can just type "jupyter notebook" to open jupyter notebook in browser and import pandas(or any package).
You can check this link:
http://conda.pydata.org/docs/test-drive.html#managing-conda
I meet the same problem in jupyter notebook, and I run the command below and solve my problem:
!pip install pandas
For Windows
The first step is to create a new conda environment. A conda environment is like a virtualenv that allows you to specify a specific version of Python and set of libraries. Run the following commands from a terminal window:
conda create -n name_of_my_env python
This will create a minimal environment with only Python installed in it. To put your self inside this environment run:
source activate name_of_my_env
On Windows the command is:
activate name_of_my_env
The final step required is to install pandas. This can be done with the following command:
conda install pandas
To install a specific pandas version:
conda install pandas=0.20.3
To install other packages, IPython for example:
conda install ipython
To install the full Anaconda distribution:
conda install anaconda
If you need packages that are available to pip but not conda, then install pip, and then use pip to install those packages:
conda install pip
pip install django
Simple solution : In a Notebook's cell type and execute the code:
import sys
!{sys.executable} -m pip install pandas
Ｉuse window 7 for work and I had the same problems when I tried to import Pandas. So I tried to install packages under each environment:
Run cmd and type the following code:
activate py27
conda install pandas
If the system asks you do you want to install the following new packages, choose Y for [yes]
And install pandas for each different environment if you installed Python27, Python 35 and Python 36, as I did.
Then problem solved if you run jupyter notebook again and you can import pandas successfully.
You can also solve the same problem for packages like numpy, scipy, etc..
Maybe its a broken (pip) installation. Following worked for me:
sudo apt --fix-broken install
Followed by:
sudo pip3 install pandas
Hope this helps.
I was getting the error
modulenotfounderror: no module named 'pandas'
in jupyter.
I tried the command:
!pip install pandas
and it worked like a charm.
My pandas version was 0.20.3 I have updated to 0.25 using conda update pandas. I have checked in Command Line Interface(CLI) its pd.__version__ '0.25.1'.
In Jupyter notebook its showing '0.20.3'.
Please restart jupyter notebook. note is cache your pandas. or you can create a new notebook
One silly mistake that you could make is to invoke Jupyter with your local machine
python installation and not the anaconda python. I had the same problem and just
setting the PATH did not work for me.
FIX: By default, anaconda binaries are in "<Path_to_anaconda>/bin". For example, in my case, they are in "/home/klakhotia/anaconda3/bin". This directory will also contain the binary to anaconda jupyter. Launch the jupyter from here or create an alias in your .bashrc that points to this file.
What worked for me was:
pip3 install pandas jupyter
I'm using Anaconda on Windows x64. I'm trying to install some library using pip. However, the the command line isn't recognizing pip or any other scripts. The folder that they are all in is in both the user and system PATH variable. pip is there and works if I use the entire file path. Is there a way to fix this?
When creating your environment, you need to specify pip as a dependency:
conda create --name my-env pip
activate my-env
pip install ...
Installing a new environment with all default anaconda packages:
conda create --name my-env anaconda
Do this worked for me:
conda install pip
and try:
pip install package_name
Make sure you have the following dir added to PATH:
C:\Python27\Scripts
I worked for me if I start cmd and do cd C:\Users\ComputerName\Python27\Scripts
Then I typed in 'pip install "library"' and it worked!
If you don't know how to access cmd just press Win+R and type in cmd!
Hope it helped!
Try typing
python -m pip install --upgrade pip
in CMD
It worked for me.
I had it myself because of my username which uses this character "ï" which causes an encoding problem in the PATH variable. Therefore, scripts cannot be found by anaconda.
I had to install Anaconda For everyone and not just the current user to solve this problem.
Add script folder location to path, for individual user installation it will be "C:\Users\<user>\Anaconda3\Scripts" and for everyone installation it can be found in Program Files "C:\Program Files\Anaconda3\Scripts"
