Hey @bheemuni-raju, thanks for raising! Which version of whispers are you using?

[bheemuni-raju]

Hi @adeptex I'm using whispers 2.0.5 version.

[bheemuni-raju]

Hi @adeptex Any update on this?

[adeptex]

hey @bheemuni-raju, I think the problem is with having dataclasses installed. So short term fix is to pip3 uninstall dataclasses on Python 3.9.. but i have not yet done any testing.

Also FYI, this repo is for version 1. Version 2 is at https://github.com/adeptex/whispers, so the changes will be implemented there.

hi @bheemuni-raju did you try uninstalling dataclasses? Did it work for you?

hey @bheemuni-raju, this issue is addressed in 2.0.6 - https://github.com/adeptex/whispers
