Facing issue in configuring Learn-to-rank ElasticSearch plugin demo

Elastic Stack Elasticsearch
1

I am trying to configure learning-to-rank (ltr) same demo on my machine as this one. I have installed ElasticSearch 5.4, python 3.6 (it include pip), request libraries and learning-to-rank plugin 0.1.1. "tmdb" index created and documents also exist in it and elasticsearch queries are working on it. But when I execute python train.py command, it generates following error.

Note: I am working on windows server.

Note: It's mentioned in error that elasticsearch can't recognize sltr but ltr plugin is installed.

Linking to StackOverflow and not asking any question is not useful for anyone.

Please repost your topic, ask an actual question, give details, etc.

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with </> icon. Check the preview window.

Make sure you restarted your nodes and check what you have when running GET _cat/plugins?v. You can share it here.

I have installed elasticsearch as a service and I just restart (stop/start) it.
Now getting response from command http://localhost:9200/_nodes/_local/plugins?pretty=true

"plugins" : [
{
"name" : "ltr-query",
"version" : "0.1.1-es5.4.0",
"description" : "Learing to Rank Query w/ RankLib Models",
"classname" : "com.o19s.es.ltr.query.LtrQueryParserPlugin",
"has_native_controller" : false
}
],
