issue while loading paddlezoo MobileNetV3 (params issue)

Description

According to the https://docs.djl.ai/docs/paddlepaddle/how_to_create_paddlepaddle_model.html, i would like to utilize mobilenetv3. I download the model and then zip folder mobilenet including two files “models and params” as mobilenet.zip. Then i provide the zip path in my os and give the mobilenet as

        Criteria<Image, Classifications> criteria;
        try {
            translator = ImageClassificationTranslator.builder()
                    .addTransform(new Resize(IMAGE_WIDTH, IMAGE_HEIGHT))
                    .addTransform(new ToTensor()) // HWC -> CHW div(255)
                    .addTransform(
                            new Normalize(
                                    new float[]{0.5f, 0.5f, 0.5f},
                                    new float[]{1.0f, 1.0f, 1.0f}))
                    .addTransform(nd -> nd.flip(0)) // RGB -> GBR
                    .build();
            criteria = Criteria.builder()
                    .optApplication(Application.CV.IMAGE_CLASSIFICATION)
                    .setTypes(Image.class, Classifications.class)
                    .optModelPath(Paths.get("models/mobilenet.zip"))
                    .optModelName("mobilenet")
                    .optTranslator(translator)
                    .build();
            model = criteria.loadModel();

at criteria.loadModel() something went wrong and exception was raised

java.io.FileNotFoundException: Parameter file with prefix: 58cef0a19dbf1b67648f54a5cfa5df2d not found in: C:\Users\cezerilab.djl.ai\cache\repo\model\undefined\ai\djl\localmodelzoo\58cef0a19dbf1b67648f54a5cfa5df2d

how can i resolve this issue? Parameter file with prefix means actually what?

Thanks for your cooperations.

Regards.

Huge thanks, i made a mistake on resize method as you mentioned, and now when i fixed it everything run well.

Can you check what size you are resizing to ?
