[英]TensorFlow: Restoring a model
I'm trying to save my model at the end of triaining and restore it every time the training begins. 我正在尝试在三级练习结束时保存我的模型,并在每次训练开始时将其还原。 I just followed what this link did.
我只是关注此链接的作用 。
saver = tf.train.Saver()
with tf.Session(graph=graph) as session:
# Initializate the weights and biases
tf.global_variables_initializer().run()
new_saver = tf.train.import_meta_graph('model.meta')
new_saver.restore(sess,tf.train.latest_checkpoint('./'))
W1 = session.run(W)
print(W1)
for curr_epoch in range(num_epochs):
train_cost = train_ler = 0
start = time.time()
for batch in range(num_batches_per_epoch):
...Some training...
W2 = session.run(W)
print(W2)
save_path = saver.save(session, "models/model")
But it gives error below: 但是它在下面给出了错误:
---> new_saver.restore(session, tf.train.latest_checkpoint('./'))
SystemError: <built-in function TF_Run> returned a result with an error set
Can anyone help me please? 谁能帮我吗? Many thanks!
非常感谢!
If you're gonna load with ./ you have to make sure, that your console (that you use to start the python program) is actually set on that directory (models/). 如果要加载./,则必须确保控制台(用于启动python程序)实际上已在该目录(models /)上设置。 But in that case, it will save your new data in a new directory.
但是在这种情况下,它将把您的新数据保存在新目录中。 So load with ./models/ instead
所以加载./models/
(Also you don't need to initiate variables, the restore does that for you.) (此外,您不需要初始化变量,还原可以为您完成此操作。)
