lgpage / nbtutor Goto Github PK

I notice that the original Python Tutor application can be used with with "Python, Java, JavaScript, TypeScript, Ruby, C, and C++" programmes, though I'm not sure how it actually works...

Which got me wondering - will this plugin be able to work with other kernels? If so, to what extent might the approach generalise to other language kernels too, such as R?

I encountered a strange behavior when trying to install nbtutor.

The strange thing is that I was able to install it in my ~/tmp directory and everything worked fine. When I was trying to install it in the project directory I wanted it, I got the following error message:

[W 06:51:57.701 NotebookApp] 404 GET /nbextensions/nbtutor/js/nbtutor.deps.min.js.js (127.0.0.1) 1.260000ms referer=http://localhost:8888/notebooks/src/jupyter/Untitled.ipynb?kernel_name=python3

This is in ubuntu 20.04; python 3.8.10.

The install process (in both directories) was:

$ python3 -m venv nbtutor_venv 
$ source nbtutor_venv/bin/activate
(nbtutor_venv) $ pip install --upgrade pip
(nbtutor_venv) $ pip install nbtutor
(nbtutor_venv) $ jupyter nbextension install --overwrite --py nbtutor --sys-prefix
(nbtutor_venv) $ jupyter nbextension enable nbtutor --py --sys-prefix
(nbtutor_venv) $ jupyter notebook

I do not see any files in the project directory that might affect the behavior or jupyter... Any ideas?

Thanks a lot for such a great tool & best regards!

jsPlumb clears all connectors, not just the connectors in a specified container. I'm guessing I need to look into using jsPlumb instances.

For example

foo = list()
foo.append(foo)

"Run all cells" triggers multiple toolbar builds when the toolbar is off

Rewrite nbtutor for easier maintainability:

• Update Python code to follow a proper design pattern
• Use Angular as the front end framework
• Add Python and Angular unit tests

To provide more real estate for the stepper visualisation, it might be useful to pop the stepper visualation out into a floating JQuery dialog widget.

As a proof of concept, if we find the div id for (the div has class nbtutor-canvas) we can pop it out into its own window if we have jquery and jquery-ui loaded using the following:

%%HTML
<script>$( "#SPECIFIC_ID" ).dialog()</script>

Peeking at the code, the corresponding div appears to be defined here:

Also include IPython's out[] output.

I cannot move beyond the indicated step ...however if I use --step_all it works

how can i run this projekt on docker

I can't seem to get any of the visualization show up. I think I am doing as shown in the screencast but it doesn't work. Plus I get this when I try to turn on Memory or Timeline. What am I doing wrong? Thanks.

From https://groups.google.com/a/continuum.io/forum/#!topic/anaconda/45fNK2ni_so:

(Windows +Mac OSx) When i run "%%nbtutor -r -f" the GUI does not display on the right hand side. I have installed nbtutor and no error message is displayed.
Thank you for the help.

nbtutor makes notebook un-usable when both nbtutor and nbgrader create_assignment extensions are enabled. It is nbtutor that is breaking things with the following web console error:

too much recursion
  initEvents/CellToolbar.prototype.rebuild       nbtutor/js/nbtutor.min.js:48:1

A cell's code is pointlessly re-run again via ipython to get the "<ipython-input-{0}-{1}>" f_code.co_filename set and the code cached.

I don't know enough, yet, about the IPython API to do this better inside the debugger

Hello there,
I suspect this project is now unmaintained, last commit was in 2016...
@lgpage are you still maintaining this project?
It's very interesting and it would be valuable to keep it running! Thanks in advance!
I'm willing to try to help it, but I'm not feeling confident it taking the full responsibility.

This extension works very well for me, and I'm a big fan and intense user of the RISE jupyter extension to teach with Jupyter notebook being displayed in full screen as slides.

As shown in this demo:

using nbtutor from the RISE live show mode (regardless of being full-screen) works from the backend side, but not from the frontend UI side: the control buttons are hidden!
But exiting the RISE mode shows that the buttons are there, they work and everything is fine.

This issue is here to notify about this bug, and I can try to help, but I'm not an expert on the architecture of nbtutor, so I would need your help @lgpage!
Thanks in advance!

Add line marker legend after fixing #6

The colour theme in the animation offers low contrast displays when stepping through the trace. Is there an easy way of setting background and font colours, or selecting a high contrast / websafe / colourblind safe palette?

Look over this again.

Add a cutoff for the sizes/length of "sequence" type objects and a cell magics option

Line numbers for the line markers needs to be restricted to only the objects created in the current cell.

Hello,

I can't load nbtutor. I have tried to uninstall and reinstall nbtutor and i have no idea what is going on.
Thanks for your help !!

Hi, Logan,

I liked to try nbtutor with nbgrader. This is weird issue, after enabling nbtutor globally - I am unable to make anything with cells - especially create cell below current cell (by menu item Insert -> Insert Cell Below or by keyboard shortcut). I am sure this is nbtutor issue, because

• at another server with nbgrader (but not nbtutor enabled) it works normally
• at the server giving trouble, after disabling nbtutor, all is as it should be.

My actual software versions you can see from nbgrader issue jupyter/nbgrader#891, which I submitted today.

Edit: link to nbgrader issue

Running nbtutor in a recent Jupyter notebooks build gives a Failed to load extension - Error: Script error for "nbextensions/nbtutor/js/nbtutor.min" error?

ImportError: cannot import name 'Literal' from 'typing'

I use jupyterlab for python trainings and your extension can be very useful for this job.

Is there a plan to support Jupyterlab?

Regards

Hi Team,

I am new with jupyter notebook and pythong. I just installed fresh jupyter notebook and jupyter lab. then i followed the suggested method to install nbtutor for jupyter i.e.(conda install -c conda-forge nbtutor) after installtion when i am trying to use nbtutor in my notebook while loading nbtutor i am getting traceback saying there is not module exist. i tried multiple time but nbtutor not working. can someone help me to resolve the problem.

here is the traceback detail.

ModuleNotFoundError: No module named 'nbtutor'

Title: Missing "Visualize" option in "Cell Toolbar"

Description:
I am using nbtutor and I have noticed that the "Visualize" option is missing from the "Cell Toolbar" menu. This makes it difficult for me to use the visualization feature of nbtutor.

Steps to reproduce:

1. Open a Jupyter notebook with nbtutor installed.
2. Click on the "View" menu and select "Cell Toolbar".
3. Observe that the "Visualize" option is not present in the "Cell Toolbar" menu.

Expected behavior:
The "Visualize" option should be present in the "Cell Toolbar" menu, allowing me to use the visualization feature of nbtutor.

Actual behavior:
The "Visualize" option is missing from the "Cell Toolbar" menu.

I've install in my python repository

./pip --proxy=proxy.utbm.fr:3128 install nbtutor
./jupyter nbextension install --overwrite --py nbtutor --sys-prefix
./jupyter nbextension enable nbtutor --py --sys-prefix

now in a notebook I have in a first cell :
%load_ext nbtutor

and in a second cell :
%%nbtutor blutch = 7 print (blutch)

then I execute the code in the first cell, nothing appends

And now in a second cell, nothing happends but I have this exception (just replacing my login by ...) in my javascript console (firefox):
Exception in event handler for toolbar_rebuild.CellToolbar InternalError ​ columnNumber: 13 ​ fileName: "http://localhost:8080/user/.../static/notebook/js/main.min.js?v=fc2a61bcf6f091823db7fb553a838e7f" ​ lineNumber: 28677 ​ message: "too much recursion" ​ stack: "events.trigger@http://localhost:8080/user/.../static/notebook/js/main.min.js?v=fc2a61bcf6f091823db7fb553a838e7f:28677:13\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:22:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:23:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:23:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:23:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:23:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/.../nbextensions/create_assignment/main.js?v=20181009123455:23:9\nCellToolbar.prototype.rebuild@http://localhost:8080/user/..../nbextensions/create_assignment/main.js?v=20181…" ​ __proto__: Object { stack: "", … } Arguments ​0: "toolbar_rebuild.CellToolbar" ​1: Object { selected: false, anchor: false, rendered: true, … } ​callee: Getter & Setter ​length: 2 ​Symbol(Symbol.iterator): function values() ​__proto__: {…} ​​__defineGetter__: function __defineGetter__() ​​__defineSetter__: function __defineSetter__() ​​__lookupGetter__: function __lookupGetter__() ​​__lookupSetter__: function __lookupSetter__() ​​constructor: function Object() ​​hasOwnProperty: function hasOwnProperty() ​​isPrototypeOf: function isPrototypeOf() ​​propertyIsEnumerable: function propertyIsEnumerable() ​​toLocaleString: function toLocaleString() ​​toSource: function toSource() ​​toString: function toString() ​​valueOf: function valueOf()

Hi

Running the current dev version installed from the repo, I'm not seeing nbtutor in the classic notebook UI.
