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?
This is my test 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})
And This is the error:
Not a JPEG file: starts with 0xc3 0xbf

You're reading an image file as if it were a text file.
Just change the line:
with open(path, "r", encoding="latin-1") as f:
with
with open(path, "rb") as f:
To read the image as a binary ("rb" = Read Binary) file.
