write_documents_to_db() got an unexpected keyword argument 'only_empty_db'

[keherri]

Following the GoT tutorial I received the following error when using the write_documents_to_db(only_empty_db=True) function write_documents_to_db() got an unexpected keyword argument 'only_empty_db'.

I installed using pip install farm-haystack

Hey @keherri ,

Thanks for reporting. It's probably a version mismatch between the tutorial and the haystack version. Can you please check if this issue still occurs when installing directly from current master branch?

git clone https://github.com/deepset-ai/haystack.git
cd haystack
pip install -e .

We introduced the only_empty_db only recently and didn't do a pypi release yet since we want
to finish a few other features first. We'll probably do a release later this week.

The version on the master branch has also a few other bugfixes and supports models from huggingface's transformers.

Installing from current branch fixed issues. Thanks. Results are looking great!
