TensorFlow读取图片机制（1）--直接读取图片

读取机制有四种方法方法一直接读取图片

直接写代码

# tensorflow read picture读取图片机制
import tensorflow as tf
with tf.Session()  as sess :
    filename = [ 'C0.jpg', 'C1.jpg' ,'C2.jpg']
    filename_queue =tf.train.string_input_producer(filename ,shuffle =False ,num_epochs = 5)
    reader = tf.WholeFileReader()
    key , value =reader.read(filename_queue)
    tf.local_variables_initializer().run()
    threads = tf.train.start_queue_runners(sess= sess)
    i = 0
    while True :
        i+= 1
        image_data = sess.run(value)
        with open('tfIO/test_%d.jpg' % i, 'wb') as f :

            f.write (image_data)

会跳出OutOfRangeError (see above for traceback): FIFOQueue '_3_input_producer_1' is closed and has insufficient elements (requested 1, current size 0)

这是遇到结尾标志，正常，在相应文件中已经读取完毕
