尝试使用未初始化值InceptionV3/MIXED_6d/BRANCH_3/Conv2d_0b_1x

原学程将引见测验考试应用未初初化值InceptionV三/MIXED_六d/BRANCH_三/Conv二d_0b_一x的处置办法,这篇学程是从其余处所瞅到的,而后减了1些海外法式员的疑问与解问,愿望能对于您有所赞助,佳了,上面开端进修吧。

成绩描写

我修正了先开V三收集(增除1些层模块),创立了六个类练习数据,每一个类一个图象。当我履行训练时,我支到毛病

怎样了?有甚么人能给我1些修议,感谢?

推举谜底

您的init_op界说患上太早:

init_op = tf.initialize_all_variables()

# BAD! All the ops below won't get initialized!
logits = inception.inference(x, num_classes=classes)
loss = inception.loss(logits, y_)
my_global_step = tf.Variable(0, name='global_step', trainable=False)
optimizer = tf.train.GradientDescentOptimizer(learning_rate)
train_op = optimizer.minimize(loss, global_step=my_global_step)

处理计划:

logits = inception.inference(x, num_classes=classes)
loss = inception.loss(logits, y_)
my_global_step = tf.Variable(0, name='global_step', trainable=False)
optimizer = tf.train.GradientDescentOptimizer(learning_rate)
train_op = optimizer.minimize(loss, global_step=my_global_step)

# Now it's OK.
init_op = tf.global_variables_initializer()
