BrokenPipeError: [WinError 232] The pipe is being closed when migrating

I’m currently migrating from rasa_core 0.10 to 0.12. I had to delete some epochs or batch_size from .train() methods but now I’m nearly on the point of dialoging again with my bot but I’m encountering another issue: BrokenPipeError: [WinError 232] The pipe is being closed and an exception in a thread that ends up with AttributeError: __enter__

Do you have any idea ?

I’m using Windows10

Hi @antoinecomp,

Not sure is this is a threading error or a formatting error. What command did you use to run this and what ought the bot utter in response to this message?

Hello Tom, happy new year and thanks for your help. I only launched python and it had to answer with a greeting. Yet if I remembered well it was an error with the migration process.
