'from allennlp.commands.elmo import ElmoEmbedder' not work even in 0.9.0

[TITC]

We removed the elmo command in v1.0. If you want to use the elmo command then you need to check out v0.9.0. We removed this command because elmo is becoming a bit old and we didn't think it made sense to continue supporting it as a top-level command.

version 0.9.0 worked fine. thx.

version 0.9.0 not work for me, any advice is welcome

@TITC It appears to be because the latest overrides package breaks the older versions of allennlp (please see #5197).

As per a workaround suggested on that issue, can you try downgrading the version of overrides to 3.1.0?
