title: Not a JPEG file: starts with 0xc3 0xbf
body: <p>I am trying to decode jpeg file using tf.image.decode_jpeg but it says its not a JPEG file. I don't know what the problem is.Can anyone help me to solve this problem?</p>
  
  <p>This is my test code.</p>
  
  <pre><code>import tensorflow as tf
  
  path = "/root/PycharmProjects/mscoco/train2014/COCO_train2014_000000291797.jpg"
  
  with open(path, "r", encoding="latin-1") as f:
      image = f.read()
  
  
  encoded_jpeg = tf.placeholder(dtype=tf.string)
  decoded_jpeg = tf.image.decode_jpeg(encoded_jpeg, channels=3)
  
  sess = tf.InteractiveSession()
  
  sess.run(decoded_jpeg, feed_dict={encoded_jpeg: image})
  </code></pre>
  
  <p>And This is the error:</p>
  
  <pre><code>Not a JPEG file: starts with 0xc3 0xbf
