OutOfRangeError (see above for traceback): FIFOQueue ‘_2_batch/fifo_queue’ is closed and has insufficient elements (requested 100, current size 0)

python 在调用tensorflow模块中的批处理时出现的错误

解决方法：
观察代码中有关shape的操作
对图片的处理要根据图片的相关像素尺寸来进行set_shape

	file_queue = tf.train.string_input_producer(file_list)
 	reader = tf.WholeFileReader()
    filename, image = reader.read(file_queue)
    decoded = tf.image.decode_jpeg(image)
    # print("value", decode)  # value Tensor("DecodeJpeg:0", shape=(?, ?, ?), dtype=uint8),在进行batc时要指定好图片的格式
    decoded.set_shape([20, 80, 3])
    # 这里对解码的图片进行设置尺寸操作

如果直接这样运行就要报错
经过观察图片

更改为decoded.set_shape([60,160,3])，代码成功运行
