Known Workarounds

No response

[freefer]

Setting it to false seems to work properly

[antoniovalentini]

I'm having the same issue, and the workaround is working fine. What are the downsides of setting Embeddings = false ?

What are the downsides of setting Embeddings = false ?

embeddings generation won't work. So line 89 of the image above is suspect, it's creating an embeddings generator with embeddings = false.

This isn't fatal though, you can toggle embeddings on an offat runtime. We just need a PR to make the text generator and embeddings generator do that :)

This issue has been automatically marked as stale due to inactivity. If no further activity occurs, it will be closed in 7 days.

[martindevans]

I'm going to protect this one from auto closing until the work I mentioned (toggling embeddings at runtime) has been done.
