jre has value 1.8 but 1.7 required and then CoreNLP needs 1.8+

[ccrowner]

edited registry to 1.7 then got

JavaRuntimeVersionError too old must use 1.8+ for CoreNLP

I am using the jar_filename parameter to point to the recent stanford-parser.jar

Thanks!

Thanks for the report. Can you explain what you mean by "1.7 required" and "edited registry to 1.7"? Also, which version of the JRE is actually installed?

[ccrowner]

I have both jre 1.7 and 1.8 installed

when PyStanfordDependencies threw the JavaVersionError "jre has value 1.8
but 1.7 required" I edited the Windows registry to jre version 1.7

that worked with respect to PyStanfordDependencies BUT led to an error in
CoreNLP (the most recent version) which requires 1.8 (hence throws the
error "CoreNLP needs 1.8+")

thanks

BTW your tool promises to be very useful, all the Python wrappers on the
StanfordNLP site only run under Unix and though NLTK enables many of the
StanfordNLP components they don't wrap the DependencyParser

Can you send the full stacktrace for the "jre has value 1.8 but 1.7 required" error?

PyStanfordDependencies on its own doesn't care about the JRE versions, it just tries to detect when the jars require a different version. Are you using subprocess or JPype for your backend? (maybe JPype needs JRE 1.7 on Windows?).

OK - the program I run is stanford_dependencies_test.py (attached)

If I have jre 1.8 set in the registry

• note: the JAVA_HOME settings don't take, as well as the Control Panel
  Java settings, going to Registry does

http://stackoverflow.com/questions/26324486/properly-installing-java-8-along-with-java-7

I get dependencies_error.txt

When I set the jre to 1.7 in the registry I get dependencies_error3.txt

Thanks for looking at this. You can see I print out the command you execute
and have fiddled around with your code but got nowhere.

Hmm, sounds like having two different JREs on Windows is tricky. If it's at all possible, I would only have one version installed (though it sounds like StackOverflow users have found some workarounds).

Yeah, PyStanfordDependencies doesn't look at JAVAHOME unfortunately -- it's basically just running the java command and hoping that will run. In your case, it looks like running java triggers the error about the registry mismatch. So essentially, I think you need to find a way that running java -version prints out 1.8 without any errors. You might also want to try passing the path to a specific java binary with the java_command argument to StanfordDependencies.get_instance -- I'm not a Windows expert (nor do I have access to it) so I'm not sure if this will help.

[ccrowner]

Some good ideas, thanks.

One quick question that's probably obvious ;-)

Why are you depending upon the Stanford jar? If you can take a parse tree
and convert it into dependencies it seems that I could call the Stanford
Parser using some other wrapper (e.g. NLTK) and just pass the resulting
tree to your code (again sorry if this is obvious I didn't look so much at
your code logic - just trying to get past nit-noid version problems)

Thanks

It's a good question. PyStanfordDependencies doesn't actually know how to convert trees to dependencies, it just knows two different ways (subprocess and JPype) for calling the conversion code in Stanford CoreNLP/Stanford Parser. In other words, if there was a jar that just had the dependency conversion code in it and didn't include a parser, PyStanfordDependencies would be fine with that. It just uses Stanford CoreNLP/Parser jars by default since those are the ones that are typically distributed.

Thanks, and thanks again for contributing something useful to the community!
