Using nbgrader for Classroom

Using ngbrader in Jupyter

Install nbgrader

You can install nbgrader in a notebook:

1. Launch a Juypter session from class.osc.edu
2. Open a new notebook 
3. To Install nbgrader, run:

!pip install nbgrader
!jupyter nbextension install --sys-prefix --py nbgrader --overwrite 
!jupyter nbextension enable --sys-prefix --py nbgrader 
!jupyter serverextension enable --sys-prefix --py nbgrader

To check the installed extensions, run

!jupyter nbextension list

There are six enabled extensions

Configure nbgrader

In order to upload and collect assignments, nbgrader requires a exchange directory with write permissions for everyone. For example, to create a directory in project space, run:

%%bash
mkdir -p /fs/ess/projectID/courseID/exchange
chmod a+wx /fs/ess/projectID/courseID/exchange

Then get your cousre ID for configuratin. In a notebook, run:

%%bash
echo $OSC_CLASS_ID

Finally create the nbgrader configuration at the root of the workspace. In a notebook, run 

%%file nbgrader_config.py
c = get_config()
c.CourseDirectory.course_id = "courseID"     # it must be the value of $OSC_CLASS_ID
c.Exchange.root = "/fs/ess/projectID/courseID/exchange"
c.Exchange.timezone = 'EST'

Once the file is created, you can launch a new Jupyter session then start creating assignments. For using nbgrader, please refer the nbgrader documents.

Access assignments

To let students access the assignments, students need to have the following configuration file in the root of their workspace:

%%file nbgrader_config.py
c = get_config()
c.Exchange.root = "/fs/ess/projectID/courseID/exchange"
