jt command not installing properly

[dspoka]

Mac OS Sierra 10.13
pip 9.0.1
Python 2.7.13

I used
pip install jupyterthemes

and it seems like it installs successfully but the jt command does not exist.
have tried uninstalling and installing with sudo too.
any help?

[dunovank]

Hmm... that's a new one... I'm really not sure.
Does it work if you replace jt with jupyter-theme

as in:
jupyter-theme -t oceans16

[jasonseney]

Update - Not sure if this is the same issue, but I had to restart jupyter after setting this up for it to pick up the custom.css file for the first time.

[dunovank]

Thanks for the feedback. onedork should be one word 'jt -t onedork' . Not sure if that was a typo or not. But either way I'll need to make sure it raises an error when the theme name doesn't match any of the existing themes. Was that the issue (do you see the new theme after running 'jt -t onedork' )?. How about after refreshing the browser cache? Starting a new jupyter session? Restarting the browser and a new jupyter session?

@dunovank Thank you for the reply - I actually edited my comment after figuring it out. (Unrelated to typo of theme).

I had to restart my jupyter process and it picked it up no problem after that. I read that it only checks for the custom.css file if it's there on startup. Subsequent changes to the theme work fine after restarting. I didn't have this issue with jupyter-themer because they use an entirely different (perhaps deprecated) location for the custom CSS.

Perhaps it's worth mentioning the restart in the README? Thanks!

[dunovank]

Yes, a long needed addition to the readme. Will do that asap. Thanks again for the feedback!

[sananth12]

@dspoka I had the same issue, and this worked for me:
(First, uninstall any older versions)

pip install --user git+https://github.com/dunovank/jupyter-themes.git

[dunovank]

Thanks @sananth12 ! Putting a note in the readme about this.

[biographie]

I've tried uninstalling existing versions and re-installing from the github repo, but I'm still getting " name 'jupyter' is not defined"

I've restarted jupyter as well and nothing seems to be solving the problem. Any suggestions?

[chw946]

I've tried following the README instruction:

# uninstall any existing versions
pip uninstall jupyterthemes
# install from the github repo
pip install --user git+https://github.com/dunovank/jupyter-themes.git

but it seems my zsh still complaining

zsh: command not found: jt

Does anyone know how to solve this?

[biographie]

chw946,
I too am having the same exact problem, and using zsh. Have yet to find a solution

[dunovank]

@biographie what's the output of terminal command: echo $PYTHONPATH

(I'm also using zsh and haven't had any issues. It's been a while but I seem to remember having to manually set my PYTHONPATH to prioritize anaconda packages after installing zsh).

[biographie]

@dunovank im not getting any output when echo $PYTHONPATH

any ideas on how to go about this?

[dunovank]

disclaimer: messing with PATH variables is always risky so proceed at your own discretion

If you're using anaconda you might try adding the following lines to your .zshrc

# PATH
export PATH="$HOME/anaconda/bin:$PATH"

# PYTHONPATH
export PYTHONPATH="$PYTHONPATH:$HOME/anaconda/bin/"

or replace $HOME/anaconda/bin/ with the path that gets returned when you execute which python

[dunovank]

@biographie any luck with this?

[biographie]

@dunovank great stuff - it worked!
just one last issue which is off-topic, but using the onedork theme, all the plots i've got in r have a dark overlay. is that they way it's meant to be?

thanks a lot for your help

[dunovank]

Glad to hear it. I'm going to mark this as resolved then. Would you mind opening a separate issue about the plots? A screenshot of the issue would also help. Thanks!

[dannaf]

I guess this issue closed 3 days ago but as a first time user of jupyterthemes who just encountered it for the first time and followed the instructions in the readme I still ran into this exact problem.

Maybe the following information helps:

I am running on a fresh AWS Linux instance with Python/IPython/Jupyter installed not via Anaconda, and the pip installation (for which I need to use sudo) does seem to work normally during the installation part (before trying it). It results in an installation at /usr/local/lib/python2.7/site-packages/jupyterthemes and a short launcher file at /usr/local/bin/jt. The launcher file seems fine, and it imports main from jupyterthemes. It is there and both locate and which commands find it there.

When I try to run jt and jt -l it works, but on jt -t oceans16 it complains about permission. Then when I run sudo jt -t oceans16 this is when the sudo: jt: command not found (running bash), and which reports which: no jt in (/sbin:/bin:/usr/sbin:/usr/bin). At this point I did sudo /usr/local/bin/jt -t oceans16 and it seemed to work fine.

My conclusion/hypothesis is that the issue is a path issue specifically between sudo and non-sudo invocations, because pip seems to install it to /usr/local/bin while the sudo invocation looks in /sbin:/bin:/usr/sbin:/usr/bin where it doesn't need to find it, and the sudo invocation is necessary for proper permissions for jt -t.

Hope that helps.
Thanks!

Daniel

ps the specific permissions complaint that gets me to use sudo in the first place for jt -t is:

[ec2-user@ip-172-31-44-101 ~]$ jt -t oceans16
Traceback (most recent call last):
  File "/usr/local/bin/jt", line 11, in <module>

[dunovank]

Thanks for taking the time to give detailed feedback, very much appreciated. I'll re-open this now.

[unnir]

just want to say, I've the same issue, the solutions above did not help me.

MacOs, python 3.5, conda.

I

[dunovank]

Hey @unnir sorry about the trouble. Can you tell me the output of these two shell commands?

echo $PATH
echo $PYTHONPATH
which python

Also, are you using basic bash (default shell in os x terminal) or something like zsh? Just to be clear, you're having the same permissions issue as reported by @dannaf ?

[unnir]

@dunovank you don't have to be sorry :) everything is fine, mac is very special

echo $PATH
/Users/vadimborisov/anaconda/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Library/TeX/texbin

echo $PYTHONPATH

which python
/Users/vadimborisov/anaconda/bin/python

so, I had an empty path for $PYTHONPATH,
I updated it, and now everything works like magic 👍

thank you!

[dunovank]

Good to hear @unnir , glad it worked.

Just to clarify for anyone who runs into this issue in the future. If you get an error saying that jt has not been installed correctly when trying to install a theme, first check to make sure the prioritized version of python on your system is included in your $PYTHONPATH.

In a terminal

# points to custom python install
$ echo $PYTHONPATH
# path to current prioritized python version
$ which python

If echo $PYTHONPATH doesn't return anything, open up your shell profile and update your $PYTHONPATH to include the one returned by which python.

In your .bashrc (or equivalent)

#ex. if which python returned /home/jingyang/anaconda3/bin/python
export PYTHONPATH="/home/jingyang/anaconda3/bin/python"

Save, open a new terminal session, and retry theme install.

[ghost]

Yes, thanks @dunovank. I just installed jupyter-themes, and was having the same issue when I tried to call jt in the terminal, but updating $PYTHONPATH (which was empty) fixed the problem.

[dunovank]

closing since this seems to be resolved, thanks everyone!

[rolisanchez]

For those who still had problems even with correct PATH and PYTHONPATH
I installed jupyter-themes by using the command:

pip install --user

Which is recommended instead of using sudo, but got the zsh: command not found: jt error.

After installing with sudo instead of --user (not recommended) the jt command worked.

[xshi0001]

Hi , I want to ask a question that is it useful for windows 10 to use these themes?

[unnir]

@xshi0001 usefulness of something is always up to you.

[ZhangHongdaZWQ]

Why did my jupyter notebook and the web site post a different picture when I installed it all? I want the same theme as the website, how to set it? Can you help me? Thank you very much!

[wd1969]

Jt works but nothing shows.It seems to be invalid that I have made a lot of efforts. Can I provide an alternative way of operating?For example, the following can be normal.But I also need to open the toolbar and set the font.
Set_nb_theme('chesterish')
hope to help Thank you

[RootofalleviI]

Hello! After updating my PYTHONPATH variable, the command jt still doesn't work. Could you help me? Thanks! (I'm using Ubuntu 17.10)

[yanghtr]

@RootofalleviI
I also meet the problem.
I think you can use find / -name "jt" to find where is jt
I find my jt is in ~/.local/lib/python3.5/site-packages/bin while my python is in /usr/local/bin
Then I

cd ~/.local/lib/python3.5/site-packages/bin  

python jt -l  

python jt -t oceans16

[namanpaul]

I am facing the same issue as @RootofalleviI , the PYTHONPATH variable fails to retain the path value. Any help or work around would be much appreciated. I am using Ubuntu 18.04.1 LTS

Thanks!

[nickreader]

Hi all,

I used jupyterthemes on a Mac at my work and it has worked fine. I've switched to a Windows and after installing jupyterthemes using pip when I try to set a theme by typing:
! jt -t oceans16

I have been getting this error:

'jt' is not recognized as an internal or external command, operable program or batch file.

I'm on Windows 10, Python 3.7. I have been looking through this thread for fixes but all the suggestions are for Mac. Any idea on how to fix this problem for Windows?

[benfolsom]

Thanks!

@namanpaul I'm also on Ubuntu 18.04.1. Try uninstalling and reinstalling jupyterthemes as sudo, this worked for me.

[namanpaul]

thanks @benfolsom I was able to resolve the issue on its own: the quick fix was a system restart and things seem to work!

[Marwen-Bhj]

if any is still struggling with the "jt command not found" on mac ,
these two commands seemed to resolved the issue
conda install -c conda-forge jupyterthemes
conda install -c conda-forge/label/gcc7 jupyterthemes

[pheaktra1]

Can anyone help me please?
After I installed jupyterthemes, my jupyter server is not responding. I can't use my jupyter right now.
I tried to uninstall jupyterthemes but it's still not responding. (I'm using ubuntu 16.04)
How can i get my jupyter back please?

[bukhbayar]

Are we be able to apply it in Github or it is only for local?

[FathiahHusna]

I used to have the same issue. then i uninstall. and reinstall by referring this link. and it works!!
[Change Theme for Jupyter Notebook Python. Easy steps]https://www.youtube.com/watch?v=gjxrDf6Pp6M(url)

[sid3r]

jupyter-theme -t oceans16

Worked for me, thanx.

[codtiger]

I don't if anyone else has this problem, but after setting the $PYTHONPATH, I installed the package and the command still wasn't part of the binaries. Then I updated the package using sudo pip3 install --upgrade jupyterthemes and now the command is found!

what...

[gbaldi96]

I have no clue what this means

[FiReTiTi]

I work on MacOSX 10.15 and python 3.6, and it does not work.

I configure $PYTHONPATH, reinstalled jupyter-themes with sudo and pip, tried jt,jupytertheme , jupyterthemes, jupyter-theme, etc., I still get the error:

NameError: name 'jt' is not defined

Anymore things/tricks I could try?

@gbaldi96 : do you know how to use a terminal?

[ArjitJ]

I had the same issue on Windows 10. This is what worked for me.
Find the directory for storing site-packages using python -m site.
The parent directory of site-packages contains a directory (Scripts in Windows) which needs to be added to PATH.

[miaozj]

@RootofalleviI
I also meet the problem.

I find my jt is in ~/.local/lib/python3.5/site-packages/bin while my python is in /usr/local/bin

Then when I run sudo jt -t oceans16 this is when the sudo: jt: command not found (running bash), and which reports which: no jt in (/sbin:/bin:/usr/sbin:/usr/bin). At this point I did sudo /usr/local/bin/jt -t oceans16 and it seemed to work fine.

I used the method above as @RootofalleviI posted and "cd" the path where my jt is but it didn't work.
After that, I took the action as @dannaf mentioned:

sudo + "the path where 'jt' lies" + command line options

It worked! Ty

[FiReTiTi]

@miaozj thanks a lot, it works.

[calinke]

I'm not at all framilier with using my terminal (Mac running Catalina 10.15.4). When i type:

$ echo $PYTHONPATH
$ which python
nothing seems to happen.

Can anyone spell it out for me step by step?
Thanks

[azihna]

Using Ubuntu:
I had the same problem and exporting PYTHONPATH as recommended above didn't fix the issue.
I found that it was caused by this shebang at the start of the 'jt' script (located in ~/.local/bin/jt). It was always referring to the system Python and it was causing issues when I had miniconda activated on my terminal.
The issue was resolved by changing the shebang at the start to:
#! /usr/bin/env python

Thanks for the help to find the path to jt. It was actually an executable command, not a directory, so when I got to where it was, I type ./jt -t chesterish and it worked! I'm using Ubuntu 14.04, not sure if that'll make a difference. Anyways, thanks to you all again.

[XstormLeigh]

I am on Win10, ran into this "jt -l" scenario. This is how it is done:
ps. I have Listary

1. use listary find where your "jupyter-theme" is
2. add that directory into your path
3. add your python library combos into your path
4. go to cmd prompt and try again your "jt -l" command, and boom!
5. that's how it is done
   

[misharoe]

I'm on windows 11.
What (finally) worked for me was typing !jt -l instead of jt -l

[MonikaRiehn]

I really loved that beautiful dark theme, but for printing I must be able to switch from dark to light quickly. Nothing of the above worked for me. The command jt could not be found, it cost me hours, tried nearly all possible solutions. The only thing that worked was to delete the custom folder from jupyter and switch to dark theme via chrome://flags.

[zsaramousavi]

I have Python 3.9.13 on windows 10 Enterorise, I have Jupyterthemes installed, I ran : echo $PYTHONPATH
AND i GOT: $PYTHONPATH
STILL jt is not recognized when I want to change the theme

[zsaramousavi]

FYI: I tried !jt as well, but did not work.
