这是我用于读取tfrecord文件的代码，它是由Github上的任何未知对象创建的，因此我试图读取它。但是我收到一个错误，如下所示。谁能解决这个问题？？？
import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
data_path = 'train.tfrecords'
with tf.Session() as sess:
feature = {'train/image': tf.FixedLenFeature([],tf.string),
'train/label': tf.FixedLenFeature([],tf.int64)}
filename_queue = tf.train.string_input_producer([data_path],num_epochs=1000)
reader = tf.TFRecordReader()
serialized_example = reader.read(queue=filename_queue,name=None)
features = tf.parse_example(serialized_example,features=feature)
image = tf.decode_raw(features['train/image'], tf.float32)
label = tf.cast(features['train/label'], tf.int32)
image = tf.reshape(image, [224, 224, 3])
images, labels = tf.train.shuffle_batch([image, label], batch_size=10, capacity=30, num_threads=1,
min_after_dequeue=10)
init_op = tf.group(tf.global_variables_initializer(), tf.local_variables_initializer())
sess.run(init_op)
coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)
for batch_index in range(5):
img, lbl = sess.run([images, labels])
img = img.astype(np.uint8)
for j in range(6):
plt.subplot(2, 3, j + 1)
plt.imshow(img[j, ...])
plt.title('cat' if lbl[j] == 0 else 'dog')
plt.show()
coord.request_stop()
coord.join(threads)
sess.close()
这是错误

我是新来的，所以对这些错误了解不多。有人能告诉我这个错误吗？
