The duckling you installed is part of the ner_duckling_http pipeline and not ner_duckling, ner_duckling is simply the python wrapper of the Clojure version of duckling. Facebook has deprecated that. You pipeline should look like this

pipeline: 
- name: "tokenizer_whitespace"
- name: "intent_entity_featurizer_regex"
- name: "ner_crf"
- name: "ner_synonyms"
- name: "intent_featurizer_count_vectors"
- name: "intent_classifier_tensorflow_embedding"
  intent_tokenization_flag: true
  intent_split_symbol: "+"
- name: "ner_duckling_http"
  url: "http://duckling:8000"
  dimensions: ["time"]

url is where you have started the duckling server.
