Hi Andrey, you can ignore these messages. They are just telling us our Google Drive sync will not take back symlinks in our code folder.
I recently increased the logging verbosity to Google Colab output cell to ensure longer life span for running projects on Colab (evidently it does not idle time out pre-maturely if some output is being dumped continuously).
You can safely switch back to Clouderizer console and start working with your project once its status changes to Running (typically within 5–10 mins for fast.ai projects)
