I am testing tf.image.decode_jpeg and I got InvalidArgumentError. I am using Python3, in order to let it act like Python2, I added encoding="latin-1"..
My Question: How can I fix this problem?
import tensorflow as tf
with open("/root/PycharmProjects/mscoco/train2014/COCO_train2014_000000291797.jpg", "r", encoding="latin-1") as f:
image = f.read()
sess = tf.Session()
result = sess.run(tf.image.decode_jpeg(image, channels=3))
This is the error.
Not a JPEG file: starts with 0xc3 0xbf

Thanks to Felix, I solved my problem by using tf.read_file
I tried to rewrite this using placeholder: And this is my 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 I got the error again, anyone can tell me how to fix it? This time, I cannot use tf.read_file() because I cannot feed a tensor to a tensor.
