我正在尝试创建一个简单的字符串标签对数据集,并且无法获得tensorflow来正确连接这些对
我正在尝试使用Dataset.from_tensor_slices初始化程序和数据集。make_one_shot_iterator迭代器:
import tensorflow as tf
strings = [
'aaaa',
'asdf'
]
labels = [1,0]
sess = tf.Session()
tf.global_variables_initializer()
dataset = tf.data.Dataset.from_tensor_slices((strings, labels))
dataset = dataset.repeat()
dataset = dataset.shuffle(512)
iterator = dataset.make_one_shot_iterator()
x_next, label_next = iterator.get_next()
print sess.run(x_next), sess.run(label_next)
x_next, label_next = iterator.get_next()
print sess.run(x_next), sess.run(label_next)
x_next, label_next = iterator.get_next()
print sess.run(x_next), sess.run(label_next)
x_next, label_next = iterator.get_next()
print sess.run(x_next), sess.run(label_next)
最后,我希望输出为'aaaa'为'1',为'asdf'为'0',但是反复得到一些随机值:
aaaa 0
asdf 0
aaaa 1
asdf 1
aaaa 1
aaaa 0
asdf 1
aaaa 1
请提出我的代码中可能有什么问题
顺便说一句,如果删除混洗,将无法获取另一个字符串,迭代器将仅输出:
aaaa 0
aaaa 0
aaaa 0
...
标签错误...有人知道开始的原因吗?
答案 0 :(得分:0)
这就是我的用法。
next = iterator.get_next()
# print(next)
with tf.Session() as sess:
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
print(sess.run(next))
(b'aaaa', 1)
(b'asdf', 0)
(b'aaaa', 1)
(b'aaaa', 1)
(b'asdf', 0)
(b'aaaa', 1)
(b'aaaa', 1)
(b'aaaa', 1)
