Hello all!
A few students have shown us that some of our tests did not work out properly, many thanks to them! Therefore, we have updated the tests and rerun your solutions one more time. Anticipating the question, most of the changes were in the `time_counter` test function whose execution apparently depended on OS you used and CPU load during a run. Please, check out updated grades in Moodle.
Who's got over 50%: well done!
Who's got less: you should pay more attention to basics of python, numpy and jupyter notebooks rather than CV materials themselves. It is highly recommended to get familiar with this technical stuff as it is ubiquitously used throughout our course as well as beyond it. For starters, check out our materials from the first Ex session https://moodlearchive.epfl.ch/2021-2022/mod/resource/view.php?id=1051356. Also, you can follow this online tutorial and practice it in jupyter notebook https://cs231n.github.io/python-numpy-tutorial/. The most important features of numpy arrays that we use plenty of times throughout the course are broadcasting and slicing, pay more attention to them.
Next exercise session (#5) will take place on the 3rd of May, the one after that (17th of May) is the 2nd graded exercise.
