'cannot find symbol' compilation error

[matlabat]

Hi,

Thanks for sharing your work.
I have a compilation error when I'm trying to compile RatioGPUDMM.java

$ javac RatioGPUDMM.java
RatioGPUDMM.java:17: error: cannot find symbol
import RatioGPUDMM.Document;
^
symbol: class Document
location: package RatioGPUDMM
RatioGPUDMM.java:26: error: cannot find symbol
public ArrayList docList;

symbol: class Document
location: class RatioGPUDMM
RatioGPUDMM.java:60: error: cannot find symbol
public RatioGPUDMM(ArrayList doc_list, int num_topic, int num_iter, int save_step, double beta,
^
symbol: class Document
location: class RatioGPUDMM
RatioGPUDMM.java:445: error: cannot find symbol
Document doc = docList.get(i);
^

location: class RatioGPUDMM
RatioGPUDMM.java:473: error: variable topic is already defined in method init_GSDMM()
int topic = rg.nextInt(numTopic);

ArrayList doc_list = new Document.LoadCorpus("corpus.txt");

7 errors

My version of java:

$ java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

I'm not really an expert of Java (Python) and I haven't found the bug.
Could you help me please?

Thx mat

One + to this issue, specially to

error: variable topic is already defined in method init_GSDMM()

Would the following change be a solution?
``

// Actual code
int[] termIDArray = docToWordIDList.get(d);
int topic = assignmentList[d];
int topic = rg.nextInt(numTopic);
assignmentList[d] = topic;
normalCount(topic, termIDArray, +1);

// Expected code?
int[] termIDArray = docToWordIDList.get(d);
int topic = assignmentList[d];
assignmentList[d] = rg.nextInt(numTopic);;
normalCount(topic, termIDArray, +1);
