ClassNotFoundException: edu.stanford.nlp.sempre.sketch.UnarySketchFn

[therealansh]

Hey, so i was looking at the source and tried

python3 synthesize_benchmark.py

but it happens to run into an error in Sempre indicating that there is some class missing.
However Docker image runs fine and produces the sketches. But i need to run it on local.

main() {

Also Sempre builds for the first time with an error

error: package org.omg.PortableInterceptor does not exist

but this is solved by removing it since it isn't used anywhere in the file. After this error is resolved I run into the above error of ClassNotFound as I stated above.

@xiye17 According to the sempre author this class "java.lang.ClassNotFoundException: edu.stanford.nlp.sempre.sketch.UnarySketchFn" is a regel-specific class. Could you look into this when available? Thanks!
