不是JPEG文件：以0xc3开头0xbf

我想使用tf.image.decode_jpeg解码jpeg文件，但它说它不是JPEG文件。我不知道问题出在哪里。任何人都可以帮我解决这个问题吗？不是JPEG文件：以0xc3开头0xbf

这是我的测试代码。

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})

，这是错误：

Not a JPEG file: starts with 0xc3 0xbf

你使用tensorflow的任何原因，而不是PIL /枕头，这是更多的蟒蛇默认库成像？ –

就好像它是一个文本文件，你正在阅读的图像文件。

只需更改行：

with open(path, "r", encoding="latin-1") as f:

与

with open(path, "rb") as f:

读取图像作为二进制（ “RB”=读取二进制）文件。

斑点。事实证明'c3 bf'是latin-1中的'ff'的UTF-8编码，它是JFIF图像标记开始的第一个字节（是二进制数据，将它解析为任何一种编码都是不正确的）。 –
