Greetings sir. Sorry when I run the Test class it returns
Cannot invoke "java.io.BufferedInputStream.close()" because "bis" is null
at com.ansj.vec.Word2VEC.loadGoogleModel(Word2VEC.java:104)
at test.Test.main(Test.java:10)
What should I do?
Can you please get back to me ASAP? I'm a bit short on time.
