$ vision deployed-models infer /tmp/hoge.JPG 
ERROR: Unknown resource -- deployed-models

Usage:  vision [--httpdetail] [--jsonoutput] [--host=<host> | --uri=<serverUri>] [--token=<token>] [--log=<level>] [-?] <resource> [<args>...]

Where:
   --httpdetail   Causes HTTP message details to be printed to STDERR
                  This information can be useful for debugging purposes or
                  to get the syntax for use with CURL.
   --jsonoutput   Intended to ease use by scripts, all output to STDOUT is in
                  JSON format. By default output to STDOUT is more human
                  friendly
   --host         Identifies the targeted MVI server. If not
                  specified here, the VAPI_HOST environment variable is used.
                  This parameter has been deprecated. It is maintained for 
                  backward compatibility, but will be removed in a future 
                  release of the tools. 
   --uri          Identifies the base URI for the MVI server -- including the
                  '/api' "directory". If not specified, VAPI_BASE_URI
                  environment variable will be used.
   --token        The API Key token. If not specified here, the
                  VAPI_TOKEN environment variable is used.
   --log          Requests logging at the indicated level. Supported levels are
                  'error', 'warn', 'info', and 'debug'
   -?  displays this help message.

   <resource> is required and must be one of:
      categories     -- work with categories within a dataset
      datasets       -- work with datasets
      files          -- work with dataset files (images and/or videos)
      fkeys          -- work with user file metadata keys
      fmetadata      -- work with user file metadata key/value pairs
      object-tags    -- work with object detection tags 
      object-labels  -- work with object detection labels (aka annotations)
      dltasks        -- work with DL training tasks
      trained-models -- work with trained models
      deployed-models -- work with deployed models
      projects       -- work with projects
