1.the model use ReshapePreProcessor ``` graphConfBuilder.addVertex(reshapedForConvName, new PreprocessorVertex(new ReshapePreProcessor( new int[] {batchSize * docLength, embeddingsDim}, new int[]{batchSize, 1, docLength, embeddingsDim})), embeddedName); ``` 2. when predict,there is only one sample ,there will be a error "Mis matched lengths",how to fix the bug?
