14、Tensorflow： tf.gfile.FastGFile造成的'utf-8' codec can't decode..错误

python3.6

tensorflow 1.4.0

 #
 #
 import matplotlib.pyplot as plt
 import tensorflow as tf
 image_raw_data = tf.gfile.FastGFile("./faceDetection/3.jpg", 'r').read()
 with tf.Session() as sess:
     img_data = tf.image.decode_bmp(image_raw_data)

     print(img_data.eval())
     plt.imshow(img_data.eval())
     plt.show()

出现错误：

 Traceback (most recent call last):
   File "e:\skh\python\readImage.py", line 5, in
     image_raw_data = tf.gfile.FastGFile("test.bmp", 'r').read()

将FastGFile对应的mode从“r”改为“rb”
