title: Ansible: tensorflow binary copy data corruption
body: <p>I'm trying to copy a TensorFlow warmup file to a server using ansible copy module. Once its gets copied the container is throwing error: </p>

  <p>I tried checking the encoding type:</p>
  
  <pre><code>[vagrant@test-machine assets.extra]$ file -i tf_serving_warmup_requests
  tf_serving_warmup_requests: application/octet-stream; charset=binary
  </code></pre>
  
  <p>Wile copying the file via scp this is working fine, but its failing while copied via ansible.</p>
  
  <p>I have also tried the ansible <strong>template</strong> module:</p>
  
  <pre><code>- name: Copy file with owner and permissions
    become: true
    become_user: "{{ app_user }}"
    template:
      src: tf_serving_warmup_requests.j2
      dest: "{{ tensorflow_warmup_dir }}/tf_serving_warmup_requests"
      output_encoding: '{{ item | default(omit, true) }}
  </code></pre>
  
  <p>But this doesn't work either. </p>
