Return wrong URI on prediction

[ozeias]

I'm trying to process more images by the time but there is a bug in the URI return.

with one url:

curl -X POST "http://localhost:8080/predict" -d '{"service":"imageserv","parameters":{"input":{"width":224,"height":224},"mllib":{"gpu": true},"output":{"best":3}},"data":["https://scontent.cdninstagram.com/t51.2885-15/e35/12519497_764907956986053_712235836_n.jpg"]}'

Result:

{
  "status": {
    "code": 200,
    "msg": "OK"
  },
  "head": {
    "method": "/predict",
    "time": 51.0,
    "service": "brands"
  },
  "body": {
    "predictions": {
      "uri": "https://scontent.cdninstagram.com/t51.2885-15/e35/12519497_764907956986053_712235836_n.jpg",
      "classes": [
        {
          "prob": 0.9500908851623535,
          "cat": "cat_1"
        },
        {
          "prob": 0.041295669972896579,
          "cat": "unknown"
        },
        {
          "last": true,
          "prob": 0.0063898079097270969,
          "cat": "cat_2"
        }
      ]
    }
  }
}

but when you send several images:

curl -X POST "http://localhost:8080/predict" -d '{"service":"imageserv","parameters":{"input":{"width":224,"height":224},"mllib":{"gpu": true},"output":{"best":3}},"data":["https://scontent.cdninstagram.com/t51.2885-15/e35/12519497_764907956986053_712235836_n.jpg", "https://scontent.cdninstagram.com/t51.2885-15/s640x640/sh0.08/e35/12093380_181967912141562_1524946174_n.jpg"]}'

results:

Thanks for catching this one. I've been able to trace it back to the parallelization of image acquisition. There should be a fix within a few hours from now. If you are in a hurry and need immediate fixing, try commenting out all the #pragma in imginputfileconn.h.

@ozeias So, please see whether the commit to master above does fix the problem for you as it does on my side and close (or not) the issue accordingly. Thanks again for the report.

@beniz seems working now. I'll make more tests but so far so good. Thanks for the quickly fix.
