Having issues importing the library

[sohanasarah]

I have this error message while trying to import any module (e.g from haystack.document_stores import InMemoryDocumentStore). I was unable to run the model before.

The error message is:

RuntimeError: Working outside of application context.

This typically means that you attempted to use functionality that needed
the current application. To solve this, set up an application context
with app.app_context(). See the documentation for more information.

@sohanasarah would you mind running pip freeze | grep farm and sharing the output of the command?

[HGamalElDiiin]

have you found any solution?

[sohanasarah]

Yes it has been resolved.

[HGamalElDiiin]
