Hello @BanKhv
TLDR; Can you submit your solution again without removing the headings provided in the starter notebook?
For the recent submissions that failed with docker build error, it is due to removing some of the blocks/headings from the notebook. We rely on the headings in the notebook to detect which part of the notebook should be run.
In this case, the submissions were failing due to missing Define preprocessing code 💻 heading after Define preprocessing code 💻 .
The following should be the structure of your notebook
# Setup AIcrowd Utilities
...
# Install packages
...
# Define preprocessing code
...
# Training phase
...
# Prediction phase
...
# Submit to AIcrowd
During the package installation phase, we run the notebook cells between # Install packages and # Define preprocessing code. During the generate predictions phase, we ignore the notebook cells between (# Install packages, # Define preprocessing code) and (# Training phase, # Prediction phase).
Please let me know if anything is unclear.
