ibm bluemix - IBM Watson Visual recognition{"code":400,"error":"Cannot execute learning task. : no classifier name given"} -


when try train classifier 2 positive classes , api key (each class contains around 1200 images) in watson visual recognition, returns "no classifier name given" - have provided. code:

     $ curl -x post -f "blank_positive_examples=@c:\users\rahansen\desktop\altmuligt\training\no_ocd\no_ocd.zip" -f "ocd_positive_examples=@c:\users\rahansen\desktop\altmuligt\training\ocd\ocd.zip" -f "name=disease" "https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classifiers?api_key={x}&version=2016-05-20"       {"code":400,"error":"cannot execute learning task.  : no classifier name given"}

what have done far:

  1. removed special characters in file names thought might problem:
  2. tried give other names classifeir, e.g. "name=ocd"
  3. i tried train on smaller dataset, 40 images in each positive class , works fine. maybe size of dataset problem. however, according watson training guidelines, comply size regulations: https://www.ibm.com/watson/developercloud/doc/visual-recognition/customizing.html btw. have free subscription.

do has recommendations how solve classifier training problem?

this can occur when there's problem processing zip files. try simplifying training files. instance, use 100 examples class, can add more via retraining later. it's train measure performance , add more training samples.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm
