Hi,

I'm doing the "Tutorial: Build Your First Question Answering System" but I have the next error:

ImportError: Failed to import 'sentence_transformers'. Run 'pip install farm-haystack[inference]'. Original error: No module named 'sentence_transformers'

Yesterday it worked, but now no and idk why.

Hey @wiskasEpiphi!

Yesterday, Haystack 1.18.0 was released and some heavy dependencies have been made optional.
Now, if you need these dependencies, you have to install Haystack using pip install farm-haystack[inference], as described in the error message.

Also the mentioned tutorial was updated accordingly, with the new installation command.
