Hello, i am getting a strange error during the compiling of a NER model. Basically, the end of the build output is:
98: ... loglikelihood=-13340.018762351776 0.999005934601099 99: ... loglikelihood=-13258.358751926637 0.9990120681028991 100: ... loglikelihood=-13178.039964721707 0.9990177634974279 Exception in thread "main" java.lang.IllegalStateException: Missing serializer for *mydictionary* at opennlp.tools.util.model.BaseModel.serialize(BaseModel.java:610) Where "mydictionary" is the key of my custom dictionary (that i add on the resources) I load the dictionary with this code: HashMap<String, Object> map = new HashMap<>(); try (InputStream modelIn = new FileInputStream("/home/damiano/mydictionary.xml")) { Dictionary dictionary = new Dictionary(modelIn); map.put("mydictionary", dictionary); } catch(Exception e) { System.out.println(e.getMessage()); } Then i create the TokenNameFinderFactory with: TokenNameFinderFactory factory = new TokenNameFinderFactory( IOUtils.toByteArray(in), map, new BioCodec() ); where "*in"* is the InputStream of my featuregenerators.xml and map is the Map with my resources. then train the model with: TokenNameFinderModel model = NameFinderME.train("it", "person", sampleStream, TrainingParameters.defaultParams(), factory); at the end i serialize the model doing: try (BufferedOutputStream modelOut = new BufferedOutputStream(new FileOutputStream(outputFile.toFile()))) { model.serialize(modelOut); } As i wrote at the beginning it cant serialize my dictionary so the build of the model does not finish properly. I read that a Dictionary can be serialized, so why this error? Thank you! Damiano
