The laboratory component of ECE 401 consists of machine problems, which you should do on your own, but you can ask for help at office hours.
General MP Instructions¶
Each MP is distributed as a ZIP archive. In the ZIP archive, you will find the following files:
submitted.py- this is the only thing you will submit. It contains several
RuntimeErrorlines that you need to replace with working code.
notebook.ipynb- this is provided to help you debug. It doesn’t need to work, but we hope that you will enjoy the MP more if you use this Jupyter notebook to help you debug
submitted.py. An example of how it should look, when everything works, will be linked from each MP’s page.
grade.py- this is the same code that the autograder runs. Before you submit to the autograder, please try running this on your own machine (
$ python grade.py). If it shows any errors, please fix them on your own machine before you try submitting to the autograder – you will save a lot of time! The autograder will run all of the same tests that are available to you, plus a few more hidden tests.
solutions.hdf5- this file contains solutions to the visible tests (but not the hidden tests). If you want to know why
grade.pyis giving you a bad score, please compare your solution to the solutions provided here. You can read this file using the H5Py for Python package.
requirements.txtlists the python packages that are used by the autograder. You can install them by typing
pip install -r requirements.txt.
How to Submit¶
When you’re ready to submit, go to Gradescope.
Submit only the one file,
submitted.py. Any other files you submit will be ignored.
You may submit as many times as you like. By default, we willl count your last submission; if you want us to grade a submission other than your last one, please select it using the Gradescope user interface.
MP Grading Policy¶
Machine problems are graded by the autograder.
You are allowed to submit any MP late, with a penalty: your MP grade will be multiplied by \(\max(0.5,1-t/20)\), where \(t\) is the lateness of your submission, in days (a real number). For example, if you’re late by one day, you can earn 95% credit; if you’re late by any number of days greater than 10, you can still earn up to 50% credit.
Warnings about the late penalty
Gradescope does not show you the late penalty. If you want to know what your score really is, you need to check Gradescope’s
latenessfield, and calculate your late penalty yourself.
The late penalty is not waived for illness, or for any other reason. The late penalty is mild on purpose, so that it is possible to recover from an illness and still submit the homework for most of the available points.
