Would it be possible to provide some further details on how to proceed to a proper submission?
Despite having passed the tests and and getting a messing acknowledging a proper submission, the leaderboard evaluation returns errors with little indications on where the error is coming from.

For example, I first wanted to use data.table library, despite having the following to work properly in the Colab notebook, it resulted in the error message "Error in data.table(x_raw) : could not find function \"data.table\"" on the submission evaluation section.

install_packages <- function() {
install.packages("data.table")
require("data.table")
}


Looking at the submissions, it seems like others also faced issues package installation/usage, so I think some further examples would be welcome.

Also, when opting for the zip submission instead of the Colab, it resulted in "DockerPushError: An image does not exist locally with the tag: aicrowd/imperial-pricing-game". The submission experience has been a little rough so far on the R side!

I’m getting the following error when running the default notebook for R:

1] “Income: 26057988.08”
[1] “Losses: 26057988.08”
[1] “Your model is invalid: it loses money on its training data!”

Hello @simon_coulombe

It’s not an error. You can submit the model and you will get a score. The message means that the performance of the model is not good.
