tf.image.decode_jpeg raise InvalidArgumentError

tf.image.decode_jpeg를 테스트하고 있는데 InvalidArgumentError가 있습니다. 어떻게이 문제를 해결할 수 있습니다 : 나는 Python2처럼 행동하게하기 위해, Python3을 사용하고 , 나는 "라틴어-1".. tf.image.decode_jpeg raise InvalidArgumentError

내 질문 = 인코딩을 추가?

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))

이

는 오류입니다. 펠릭스에

Process finished with exit code 1

덕분에, 나는이 사용하는 자리 다시 시도

tf.read_file 사용하여 내 문제를 해결 : 을 그리고 이것은 내 코드입니다 :

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})

그리고 다시 오류가 발생했습니다. 누구든지 해결 방법을 말해 줄 수 있습니까? 이번에는 텐서를 텐서에 공급할 수 없으므로 tf.read_file()을 사용할 수 없습니다. decode_jpg에

그래서, 당신은 이런 식으로 뭔가를해야합니까? 응답에 명시되지 않았기 때문에 확인하고 싶었습니다. – Steven

그럼 어떻게이 문제를 해결할 수 있습니까? – chenfei

입력 은 파일 내용 문자열 텐서이다 (여기에 API 참조) 파이썬의 read() 아닌 결과. 인코딩 부분을 추가하지 않고 그것은 실행

file_contents = tf.read_file(filename) 
image = tf.image.decode_jpeg(image, channels=3)

와우. 내 문제가 해결되었습니다. 고맙습니다! – chenfei

tf.placeholder를 사용하려고했는데 encoded_jpeg에 어떻게 피드해야합니까? – chenfei

tf.image.decode_jpeg raise InvalidArgumentError
