Pre-requisites (environment) for running haystack

[Muthusamy-J]

Hi All,

Could someone, please let me know what is the required python, pip and centos operating system version that's required to be compatible to run with the latest version of haystack to execute knowledge graph db-based question and answering ?

Hi @Muthusamy-J,

you need python 3.7 or higher for Haystack.
For pip we recommend to use the latest version, but that's not a strict requirement. If you need to stick to an earlier version, I'd suggest to try to install Haystack with it. Most of the time this should work as well.
For CentOS we do not have any specific requirements. All you need is a working pytorch environment. If the standard pip way to install it does not work, try out pytorch.org's install section (e.g. via conda envs). Appart from that you can use an in memory graph (InMemoryKnowledgeGraph) which does not require any additional software or a graphDB database (GraphDBKnowledgeGraph).
A good way to start and also to assess compatibility is to run Tutorial 10.
