If a notebook have the same name as imported package, it causes “multiple VERSIONs detected” error when importing.
I wanted to use Deck.gl in my notebook. My notebook title was deck, and I named imported package deck, which caused error like “multiple versions detected: undefined vs …” as shown in the screenshot below. Changing the notebook title and refreshing solved the problem.
Since import of deck.gl creates a variable “luma” in the global scope (deck.gl depends on luma.gl), notebook title luma also caused the same problem.
