'Python : SpaqrlWrapper, Timeout?
I am new to python as well as new to the world of querying the semantic web. I am using SPARQLWrapper library to query dbpedia, I searched the library documentation but failed to find 'timeout' for a query fired to dbpedia from sparqlWrapper.
Anyone has any idea about the same.

As of 2018, you can use SPARQLWrapper.setTimeout() to set the timeout for SPARQLWrapper requests.
Solution 2:[2]
As Karoo mentioned you can use SPARQLWrapper.setTimeout(timeout=(int)).
If you want a timeout as a float, go to the Wrapper.py module and change self.timeout = int(timeout) to self.timeout = float(timeout) in the def setTimeout(self, timeout): function.

I don't know if this is specifically an answer for your question, but I searched for it for ages and heres my solution for anyone else having trouble with Virtuoso specific timeouts on SPARQLWrapper:
Your can use this line of code to set a server-side timeout for your queries (not clientside like .setTimeout):
[your SPARQLWrapper entity].addExtraURITag("timeout","[your timeout in ms]")
In my case it looks like this:
s.addExtraURITag("timeout","10000")
This should give you 10 seconds of time before your query stops searching and returns results instead of just giving you a Timeout error.
Hope I could help anyone.
