我正在訓練Tensorflow中的卷積神經網絡。我的代碼運行完成沒有錯誤。這就是說,我很難理解我如何保存神經網絡學習的權重和偏見(當我在服務器上訓練時,這很重要,並且希望在本地執行更簡單的可視化工作)。關於在Tensorflow中保存/恢復訓練過的權重和偏差感到困惑
我初始化我的重量和偏見正是如此:
weights = {
'wConv1': tf.Variable(tf.random_normal([5, 5, 1, 3],0,0.25), name='wC1'),
'wConv2': tf.Variable(tf.random_normal([5, 5, 3, 32],0,0.25), name='wC2'),
'wConv3': tf.Variable(tf.random_normal([5, 5, 32, 64],0,0.25), name='wC3'),
'wConv4': tf.Variable(tf.random_normal([5, 5, 64, 128],0,0.25), name='wC4'),
'wConv5': tf.Variable(tf.random_normal([5, 5, 128, 64],0,0.25), name='wC5'),
'wConv6': tf.Variable(tf.random_normal([5, 5, 64, 32],0,0.25), name='wC6'),
'wConv7': tf.Variable(tf.random_normal([5, 5, 32, 16],0,0.25), name='wC7'),
'wOUT' : tf.Variable(tf.random_normal([5, 5, 16, 1],0,0.25), name='wCOUT')
}
biases = {
'bConv1': tf.Variable(tf.random_normal([3]), name='bC1'),
'bConv2': tf.Variable(tf.random_normal([32]), name='bC2'),
'bConv3': tf.Variable(tf.random_normal([64]), name='bC3'),
'bConv4': tf.Variable(tf.random_normal([128]), name='bC4'),
'bConv5': tf.Variable(tf.random_normal([64]), name='bC5'),
'bConv6': tf.Variable(tf.random_normal([32]), name='bC6'),
'bConv7': tf.Variable(tf.random_normal([16]), name='bC7'),
'bOUT': tf.Variable(tf.random_normal([1]), name='bCOUT')
}
然後,一旦然而,許多時期我運行完成後,我使用下面的保存一切:
saver = tf.train.Saver({"weights": weights, "biases": biases})
save_path = saver.save(sess, "./output/trained.ckpt")
現在,我自己機器我有一個評估腳本,其中我嘗試加載的權重:
with sess.as_default():
saver = tf.train.import_meta_graph('output.ckpt.meta')
saver.restore(sess,tf.train.latest_checkpoint('./'))
a= tf.all_variables()
sess.run(tf.global_variables_initializer())
b=sess.run(pred,feed_dict={x: input[:,:,:,30,:]})
現在,這個問題是,當我在加載「一」我得到一個爛攤子,什麼似乎是我的偏見和體重變量的多個副本:

我的問題是,我怎麼能只保存訓練的權重和偏見Tensorflow,然後加載它們以用於測試目的?
