Multiple number of classes is unknown (nclasses == 0)

[ComputerCarl]

When I attempt to add several of the services, I get the error specified in the title. Sorry, I am new at ML.

Configuration

• Version of DeepDetect: Docker Ubuntu

  nvidia-docker run -p 8080:8080 -v /home/interim/Pictures:/data/ -v /home/interim/models:/opt/models/ jolibrain/deepdetect_gpu

• Commit (shown by the server when starting):

  DeepDetect [ commit a006c4fc845cb7f9d5da604b604bf23f5d239c5c ]
  [2019-07-02 01:01:39.865] [api] [info] Running DeepDetect HTTP server on 0.0.0.0:8080

  Here are the services I am attempting to register followed by the response

Hi, can you share the exact API calls you are making to the server ?

[ComputerCarl]

Sure! Fore example, when attempting to register the real_age service from the models page. The /opt/models/age_real directory already contains;

config.json
deploy.prototxt
model.caffemodel

And this is what I enter (minus init and create_repository lines because I already downloaded and unzipped the files)

curl -X PUT 'http://localhost:8080/services/age_real' -d '{
 "description": "age estimation service",
 "model": {
  "repository": "/opt/models/age_real"
 },
 "mllib": "caffe",
 "type": "supervised",
 "parameters": {
  "input": {
   "connector": "image"
  }
 }
}'

I get response

{"status":{"code":400,"msg":"BadRequest","dd_code":1006,"dd_msg":"Service Bad Request Error: number of classes is unknown (nclasses == 0)"}}

[ComputerCarl]

Please hold off on responding.. I think I know where I messed up and am experimenting.

For others who hit this
