Avoid error ": Part 2 of Missing[RetrievalFailure]" while using EntityValue

Posted 5 years ago

As a follow-up on the "What's New in Mathematica 12" webinar, I started to familiarize myself with the Entities concept.

I understand that the EntityValue["type","Entities"] may give a larger set of entity types than the specialized types e.g. FinancialData[].

When I started to experiment with the Financial entities by retrieving all entities in EntityValue["Financial", "Entities"] I ran into two issues:

  1. It takes a very long time to complete all 660 945 entities download. On my 100 Mbps connection: a couple of hours that is..
  2. In fact it never completed and gave an error: "Part::partw: Part 2 of Missing[RetrievalFailure] does not exist."

This raises two questions:

  • Is this a known issue?
  • Moreover, is there a way to reset the entities retrieval and keep the them when the download is successful? I don't want to download them for another couple of hours on each occasion.

On a more fundamental level how will Wolfram allow for a timely download as the Knowledgeable grows in entities size?

Cheers,

Dave
