title: How to load TF hub model from local system
body: <p>One way is to download the model each time from <code>tensorflow_hub</code> like following</p>
  
  <pre><code>import tensorflow as tf
  import tensorflow_hub as hub
  
  hub_url = "https://tfhub.dev/google/tf2-preview/nnlm-en-dim128/1"
  embed = hub.KerasLayer(hub_url)
  embeddings = embed(["A long sentence.", "single-word", "http://example.com"])
  print(embeddings.shape, embeddings.dtype)
  </code></pre>
  
  <p>I want to download the file once and use again and again with out downloading each time</p>
