config.properties file

Properties for image prediction

baseURLHost = http://localhost:8888
serviceName = imageserv
inputParameters = {"width":224,"height":224}
outputParameters = {"best":5}
mlibParameters = {"gpu":false}

I am using above values for my predict request in following method -

public PredictResponse predictImages(String baseURLHost, String serviceName, String imageURL, String inputParameters, String outputParameters, String mlibParameters) {
PredictResponse response = null;
try {
response = PredictRequest.newPredictRequest() //
.baseURL(baseURLHost) //
.service(serviceName) //
.data(imageURL) //
.input(inputParameters)
.output(outputParameters)
.mllibParams(mlibParameters)
.build().process();

        System.out.println(response);
        System.out.println("\npredictions");
        for (int i = 0; i < response.getBody().getPredictions().size(); i++) {
            PredictionValue predictionValue = response.getBody().getPredictions().get(i);
            // System.out.println(" * " + words[i]);
            for (PredictionClass predictionClass : predictionValue.getClasses()) {
                System.out
                        .println("\t- " + predictionClass.getCategory() + " : " + predictionClass.getProbability());
            }
        }
    } catch (DeepDetectException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return response;
}

getting exception in doPost() method of DeepDetectRequest.java.

I have created service - imageserv in deepdetect and my deepdetect is running on port 8888

Can you please check that your server is running and reachable?

I checked for that before posting issue.. deepdetect server is running properly

DeepDetect is running on a Docker

[kfadhel]

try using 192.168.99.100:8888
as even in your console:
curl: (7) Failed to connect to localhost port 8888: Connection refused

[manaligaikwad]

tried that before posting this issue.. it was not working so I tried with localhost. But either of them is not working

[manaligaikwad]

after using 192.168.99.100:8888, stack trace is different:
I think I am doing something wrong at the time of predict request creation.

[kfadhel]

this means Bad Request – Malformed syntax in request or JSON body
can you display *Parameters passed to the method before calling the predict server?
I am working on an other issue to use objects instead of strings as requests parameters

[manaligaikwad]

these are the parameters I am passing to a method before calling predict :
baseURLHost = http://192.168.99.100:8888
serviceName = imageserv
inputParameters = {"width":224,"height":224}
outputParameters = {"best":5}
mlibParameters = {"gpu":false}
imageURL = https://www.google.ca/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwj_r7-B98vNAhVL5GMKHToHDBAQjRwIBw&url=https%3A%2F%2Fdavechampionsliberty.com%2F2015%2F09%2Ffact-there-is-no-war-on-police%2F&psig=AFQjCNFzfZ_mHNtPqBabXHTbl54nKr0_9g&ust=1467244811402590

These are all string values I am reading them from a property file.

This is the Entity object getting created for above data -

Entity{entity={"service":"imageserv","parameters":{"input":{"width":224,"height":224},"output":{"best":5},"mllib":{"gpu":false}},"data":["https://www.google.ca/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwj_r7-B98vNAhVL5GMKHToHDBAQjRwIBw&url=https%3A%2F%2Fdavechampionsliberty.com%2F2015%2F09%2Ffact-there-is-no-war-on-police%2F&psig=AFQjCNFzfZ_mHNtPqBabXHTbl54nKr0_9g&ust=1467244811402590"]}, variant=Variant[mediaType=application/json, language=null, encoding=null], annotations=[]}

[manaligaikwad]

My issue is resolved... URL I was using was invalid. I tried with different image URL and it worked.
Thank you.

[kfadhel]

I need to make the error message clear
