Running the Google Colab throws exception

When running the notebook top to bottom we get following error for the second cell:

document-question-answering is already registered. Overwriting pipeline for task document-question-answering...

I get the same exception when running the following with my local install.

docquery scan "who authored this paper?" https://arxiv.org/pdf/2101.07597.pdf

I would really appreciate a fix, since I'm really curious of trying out docquery

Regards!

I found the workaround on #60
