Highlights of nbgrader

Instructor toolbar extension for Jupyter notebooks

The nbgrader toolbar extension for Jupyter notebooks guides the instructor through assignment and grading tasks using the familiar Jupyter notebook interface.

Instructor "formgrader" extension for Jupyter notebooks

The formgrader extension for the Jupyter notebook allows instructors to use the core functionality of nbgrader---generating the student version of an assignment, releasing assignments to students, collecting assignments, autograding submissions, and manually grading submissions.

Student assignment list extension for Jupyter notebooks

Using the assignment list extension, students may conveniently view, fetch, submit, and validate their assignments.

The command line tools of nbgrader

Command line tools offer an efficient way for the instructor to generate, assign, release, collect, and grade notebooks.

Comments

Port the notebook extensions to JupyterLab

This is so we can discuss whether this is the right path to follow for nbgrader, I'm not 100% sure yet but at least we can come to a decision here...

We're still using nbgrader at Cal quite a bit, and as I consider moving the students more to JupyterLab as their "daily driver", the absence of the student-facing extension for submitting notebooks is becoming a more relevant issue.

Curious what @jhamrick @ellisonbg think in this context - how realistic would it be to put some cycles into porting the extension? This is more of an nbgrader than a Lab issue, but it's turning out to be kind of a blocker to our use of Lab by default (which I really want to do :).

CC @jasongrout @ian-r-rose as per recent discussions on blockers and extensions...

Jupyterlab extensions

This PR brings the jupyterlab extensions to nbgrader.

It is an improvement of the work done by @Lawrence37 and @aalmanza1998 in https://github.com/LibreTexts/nbgrader-to-jupyterlab/tree/lab-common.

It works with jupyterlab < 4 and is still compatible with classic notebook (nbextensions still work).

Still missing some tests on labextensions (formgrader and course list), which could be added in a future PR.

@fcollonval also helped with this PR.

Integrate feedback distribution within nbgrader

This is the result of the work of @dsblank, @perllaghu, @billywardrop29 and @danielmaitre at the Edinburgh hackathon.

It includes UI integration of the feedback step, release of the feedback to students in the exchange, and fetching of this feedback by the students.

Some UI work needs to be finished but starting a PR will help check the coverage of the existing tests.

Fixes #795 Replaces #1096

0.8 Release Plan
This is an issue for 0.8 release plan, to port nbgrader extensions to notebook 7

Classic notebook extensions system and notebook 7 extensions system (labextension) are not compatibles. Consequently, the first step would be to move the current master branch to a 0.7.x branch (a branch which keep compatibility with Classic Notebook), and use the master branch for 0.8 release (compatible with Notebook 7 and Jupyterlab).

That 0.8 release would have the following steps :

[x] move current master branch to 0.7.x branch

[x] rename master branch to main

[x] adopt juputer releaser (#1570)

[x] migrate server extension to jupyter_server (#1465)

[x] port Notebook extensions to Jupyterlab extensions (#1006, #1550)

We're creating a maintainer team! Join us :D

Hi all,

We're hoping some of our long-time users or enthusiasts for nbgrader would like to be part of a team of individuals maintaining nbgrader.

We've structured JupyterHub and Binder in a similar way. See https://jupyterhub-team-compass.readthedocs.io/en/latest/team.html#jupyterhub-team

Allow instructors to share files via shared group id
Hi,

I have been working on a setup where I wanted instructors to be able to share releasing files, collecting, and so on.nbgrader says that it doesn't support this, but I tried anyway. This PR contains the changes needed to make this work, which have been mostly minimal. Things are not perfect, and some of these changes may be not needed. I'm still testing locally and this is mainly to get some more expert opinions.

This adds a new option groupshared which enables the behavior. By default, no behavior should change.

These changes assume that the following are set by the environment (admins). They are satisfied in my setup because we run via kubespawner and I carefully control these:

instructors have a unique-per-course primary gid which students do not have. Alternatively, the setgid bit could be set (in practice I do both). If using setgid, you have to set that up yourself.

umasks are 0007

shared course and exchange directories, like normal.

Instructors won't do something wrong with permissions which breaks the security.

We expect these behaviors to happen when groupshared = True:

All info in the course directory is g+rw. Instructors can all edit files.

Multiple instructors can release and collect files from the exchange. Basically, when releasing, group permissions mirror user, not other. Because the submitted folder is set g+rwx, other instructors can also collect.

Don't insist on non-group writability in some places.

It actually seems to mostly work (though I am still doing internal tests) Remaining problems (I will keep updating this as I find more):

[x] The groupshared set in two places. Set it only once. (I didn't see a common base class...)

[x] when the release/ and release/{assignment_id} directories are created, it is g-w. Haven't been able to figure out why yet - it is not the umask, and I can't figure out where in the code the dirs are created. (help requested!)

[x] sqlite3 hardcodes a create mode of 644. I hacked around this by touching gradebook.db and setting a proper mode first.

[x] tests

[x] Study 664 vs 444 as default permissions for autograde. (rkdarst)

[x] Study what the problem with ensure_root was (rkdarst)

For now I am trying to just make something that will work, then I can work on improving it more. What do you think? Is this something that I should work on to merge upstream?

nbgrader authentication

Hey @jhamrick ,

Here's a simple extensible authentication scheme.

FormgradeApp.authenticator_class can be used to change the authenticator. BaseAuth is the base authenticator class. A NoAuth class is provided as the default, and retains current behavior of formgrade. I moved the start_nbserver traitlet and nbserver launching logic into NoAuth.

The HubAuth, empty now, will contain the logic for authenticating with JupyterHub.

Let me know what you think of this design. I've tested it locally and everything seems to work as-is. The not yet implement HubAuth can be tested quickly (when it's done) using nbgrader formgrade --FormgradeApp.authenticator_class='nbgrader.auth.hubauth.HubAuth'.

Pluggable exchange
Based on discussions with @BertR and @perllaghu, I've created a pluggable version of the exchange, to allow custom exchanges for people who don't want to/can't use the default one. See #1130 for a bit more information.

The exchange file-tree has changed as follows:

exchange/ ├── abc/ │ ├── collect.py │ ├── ... │ └── submit.py ├── default/ │ ├── collect.py │ ├── ... │ └── submit.py └── exchange_factory.py

Here abc/ contains abstract classes for each different exchange service (they aren't literally abstract, as the ABC meta-class conflicts with the LoggingConfigurable meta-class). The default/ folder contains the default implementations for each exchange service, which is just the old implementation.

The exchange_factory.py file contains the ExchangeFactory class, which is the interface for creating pluggable exchange services. It uses the Type traitlet for class variables for each exchange service, which is set to be a subclass of the corresponding class in abc/ and defaults to the corresponding class in default/.

The ExchangeFactory class has instance methods that instantiate each of the exchange services. The new way of constructing the exchange classes would look something like:

# lister = ExchangeLister(...) # old way exchange = ExchangeFactory(config=config) # or parent=self, or similar lister = exchange.List(...)

For the apps, I've created an instance variable in the NbGrader app for the ExchangeFactory class, so that subclasses can use self.exchange. to create the services. The ExchangeFactory class gets initiated and configured in NbGrader.start, so before that method has been called, subclasses can't access the self.exchange variable. (Note, I removed line 39 in dbapp.py as it was creating a ExchangeList object and assigning it to an unused variable. Since this was done before the call to NbGrader.start it couldn't use the self.exchange, and as it was unused anyway, I figured I'd just delete the line.)

I also updated server_extensions/assignment_list/handlers.py to use the new pluggable exchange.

Finally, I should note that the method names in the ExchangeFactory class do not conform to PEP8. I did this to keep the names as close to the previous names as possible. If this is an issue, it should not be too much of a problem to change the names at this point.

Hope this all made sense.

Multiple instructors, multiple courses, and multiple solutions

This is a discussion-point, to try and bring together the various threads

We have a number of similar threads on multiple courses, multiple instructors, and the possibility of an external exchange service.

We all want to use NBGrader, as it's an excellent tool for creating tests & grading the responses.

It would be good to get a common solution, or at least several non-exclusive solutions, for these issues.

Please could people describe what they are trying to achieve, and the environment in wich they are running nbgrader?

different hashing in release_feedback and fetch_feedback

0.8.0

jupyterhub --version (if used with JupyterHub)

2.3.1

jupyter notebook --version

3.4.6

Expected behavior

same result from notebook_hash in release_feedback.py and fetch_feedback.py

Actual behavior

different results, resulting in [FetchFeedbackApp | WARNING] Could not find feedback for ... during nbgrader fetch_feedback --debug

Steps to reproduce the behavior

As instructor do nbgrader release_feedback --debug <assignment>. Then as student do nbgradere fetch_feedback --debug <assignment>.

Explanation

We are using nbgrader with jupyterhub and jupyter lab for one of our courses much to our liking. For several months all was working well but very recently we stumbled on the following incident. Two students (of 20) are not able to fetch the feedback of one particular assignment.

After some debugging I found that the hash in release_feedback.py was generated with different values than in fetch_feedback.py:

nbgrader release_feedback --debug 'Assignment 3 Wavefront sensing

[ReleaseFeedbackApp | DEBUG] nbfile is: /home/grader-ap3122/ap3122/submitted/<username>/Assignment 3 Wavefront sensing/Assignment Wavefront aberrations.ipynb [ReleaseFeedbackApp | DEBUG] Unique key is: ap3122+Assignment 3 Wavefront sensing+Assignment Wavefront aberrations+<username>+2022-11-11 15:17:36.574853 UTC [ReleaseFeedbackApp | DEBUG] checksum is: f9990f2f5f029af5091cbc417c5a591e [ReleaseFeedbackApp | DEBUG] dest is: /usr/local/share/nbgrader/exchange/ap3122/feedback/f9990f2f5f029af5091cbc417c5a591e.html

nbgrader fetch_feedback --debug 'Assignment 3 Wavefront sensing

[FetchFeedbackApp | DEBUG] notebook is: /data/jupyterhub/home/<username>/.local/share/jupyter/nbgrader_cache/ap3122/<username>+Assignment 3 Wavefront sensing+2022-11-11 15:17:36.574853 UTC/Assignment Wavefront aberrations.ipynb [FetchFeedbackApp | DEBUG] Unique key is: ap3122+Assignment 3 Wavefront sensing+Assignment Wavefront aberrations+<username>+2022-11-11 15:17:36.574853 UTC [FetchFeedbackApp | DEBUG] nb_hash is: 209d0cfb1a1a05ba8d64273f2fd04271 [FetchFeedbackApp | DEBUG] feedbackpath is: /usr/local/share/nbgrader/exchange/ap3122/feedback/209d0cfb1a1a05ba8d64273f2fd04271.html

the student name has been replaced with <username>

I've added some debugging code to the two python-scripts logging the values of the appropriate variables

Clearly the nbfile and notebook have very different value resulting in different hash values. This is reflected in the different values of dest and feedbackpath which should be the same.

v0.6.0(Aug 25, 2019)
nbgrader version 0.6.0 is a major release, involving over 100 PRs and 60 issues. This includes many bug fixes, small enhancements, and improved docs. The major new features include:

Better support for multiple classes with JupyterHub. In particular, a new "Course List" extension has been added which provides instructors access to separate formgrader instances for all the classes they can manage. Additionally, JupyterHub authentication is used to control which students have access to which assignments.

Better LMS integration (for example, adding a lms_user_id column in the Student table of the database).

Better support for feedback. In particular, there is now the ability to generate and return feedback to students through nbgrader with the generate_feedback and release_feedback commands, and the ability for students to fetch feedback with the fetch_feedback command. This functionality is also available through the formgrader and Assignment List extensions.

Instructions for how to do grading inside a Docker container, for increased protection against malicious code submitted by students.

A new type of nbgrader cell called a "task" cell which supports more open-ended solutions which may span multiple cells.

Important: Users updating from 0.5.x to 0.6.0 should be aware that they will need to do the following (please make sure to back up your files before doing so, just in case anything goes wrong!):

Update their nbgrader database using nbgrader db upgrade.

Update the metadata in their assignments using nbgrader update.

Reinstall the nbgrader extensions (see :doc:/user_guide/installation).

Please also note that some of the nbgrader commands have been renamed, for consistency with the new feedback commands:

nbgrader assign is now nbgrader generate_assignment

nbgrader release is now nbgrader release_assignment

nbgrader fetch is now nbgrader fetch_assignment

v0.5.1(Jul 10, 2017)
nbgrader version 0.5.1 is a bugfix release mainly fixing an issue with the formgrader. The following PRs were merged:

PR #792: Make sure relative paths to source and release dirs are correct

PR #791: Use the correct version number in the docs

Source code(tar.gz)
Source code(zip)
v0.5.0(Jul 8, 2017)
nbgrader version 0.5.0 is another very large release with some very exciting new features! The highlights include:

The formgrader is now an extension to the notebook, rather than a standalone service.

The formgrader also includes functionality for running nbgrader assign, nbgrader release, nbgrader collect, and nbgrader autograde directly from the browser.

A new command nbgrader zip_collect, which helps with collecting assignment files downloaded from a LMS.

Hidden test cases are now supported.

A lot of functionality has moved into standalone objects that can be called directly from Python, as well as a high-level Python API in nbgrader.apps.NbGraderAPI (see http://nbgrader.readthedocs.io/en/latest/api/high_level_api.html ).

A new Validate notebook extension, which allows students to validate an assignment notebook from the notebook itself (this is equivalent functionality to the "Validate" button in the Assignment List extension, but without requiring students to be using the Assignment List).

A new command nbgrader db upgrade, which allows you to migrate your nbgrader database to the latest version without having to manually execute SQL commands.

New cells when using the Create Assignment extension will automatically given randomly generated ids, so you don't have to set them yourself.

You can assign extra credit when using the formgrader.

Important: Users updating from 0.4.x to 0.5.0 should be aware that they will need to update their nbgrader database using nbgrader db upgrade and will need to reinstall the nbgrader extensions (see http://nbgrader.readthedocs.io/en/latest/user_guide/installation.html ). Additionally, the configuration necessary to use the formgrader with JupyterHub has changed, though it is now much more straightforward (see http://nbgrader.readthedocs.io/en/latest/configuration/jupyterhub_config.html ).

Support for native Jupyter nbextension and serverextension installation, and deprecation of the nbgrader nbextension command

Buttons to reveal students' names in the formgrader

Better reporting of errors and invalid submissions in the "Assignment List" extension

Addition of a menu to change between different courses in the "Assignment List" extension

Support to run the formgrader as an official JupyterHub service

More flexible code and text stubs when creating assignments

More thorough documentations

Important: Users updating from 0.3.x to 0.4.0 should be aware that they will need to update the metadata in their assignments using nbgrader update and will need to reinstall the nbgrader extensions (see http://nbgrader.readthedocs.io/en/stable/user_guide/installation.html#nbgrader-extensions). Additionally, the configuration necessary to use the formgrader with JupyterHub has changed, though it is now much less brittle (see http://nbgrader.readthedocs.io/en/stable/configuration/jupyterhub_config.html).

0.1.0(Aug 19, 2015)
I’m happy to announce that the first version of nbgrader has (finally) been released! nbgrader is a tool that I’ve been working on for a little over a year now which provides a suite of tools for creating, releasing, and grading assignments in the Jupyter notebook. So far, nbgrader has been used to grade assignments for the class I ran in the spring, as well as two classes that Brian Granger has taught.

If you have any questions, comments, suggestions, etc., please do open an issue on the bugtracker. This is still a very new tool, so I am sure there is a lot that can be improved upon!

Thanks so much to all of the people who have contributed to this release by reporting issues and/or submitting PRs:
