Thank you @kwetstone and @jayqi . You are correct. The error was being caused by nested folders being added when the submission folder was zipped. I’ve now been able to make a submission.
For others who may read this thread, this is how I solved the problem on Mac by using the terminal to zip the folder:
- Place the folder named “submission” on the Desktop
- Open the terminal
- $ cd Desktop
- $ zip -j submission.zip submission/*
As a side note, the example_submission main.py cannot be submitted because there’s an error in the code:
Line 19: predictions[“InjuryLocationType”] = 11
InjuryLocationType can only have values from 1 to 6.
