Description

loading traindModel (bin file) throws exception I used this code to load the bin file :

InputStream inputStream = DocumentCategrizer.class.getClassLoader().getResourceAsStream("trainedModel/en-sport.bin");
DoccatModel doccatModel = new DoccatModel(inputStream);

and this is the exception I'm facing :

SEVERE: null
