running ExperimentRunner problem

[dtjayaaa12345]

Hi Dr.gradner,
I'm recently learning your pra algorthm,and using the code to run some examples in the codebase.
I just do the options like sbt "run ./examples/ final_emnlp2015",and there are many errors like that

mg1@slave2 ~/pra

$ sbt "run ./examples/ final_emnlp2015"

because i just started to learn scala ,can you give some advice? Thank you very much!

[matt-gardner]

You can see from the line [error] at edu.cmu.ml.rtw.pra.graphs.GraphCreator.createGraphChiRelationGraph(GraphCreator.scala:76) that the code is trying to create a graph. It shouldn't be doing that, because I provided the graph in the data download. It appears that you didn't unpack the graph into the right place. You should have a directory like ./examples/graphs/nell/kb_svo/, with files in it like node_dict.tsv, edge_dict.tsv, and graph_chi/.

Also, I am certain that some of the experiments in final_emnlp2015 will fail, because I didn't provide enough input to reproduce all of the experiments. Try just running sfe_bfs_pra_anyrel first.

Dr.gardner：
I just run the sfe_bfs_pra_anyrel , it succeed.And i realized the error you said above, thank you!
