Я пытаюсь не использовать нейронную сеть с симулятором трафика SUMO и TracI (инструмент SUMO), но у меня ошибка при инициализации моей сети
Я сейчас добавил:
with tf.Session() as sess:
# Initialize the variables or load a network
sess.run(tf.global_variables_initializer())
После создания моей сети с этой строкой:
DQNetwork = DQNetwork(state_size, action_size, learning_rate)
Вот код моей DQNetwork:
class DQNetwork:
def __init__(self, state_size, action_size, learning_rate, name='DQNetwork'):
self.state_size = state_size
self.action_size = action_size
self.learning_rate = learning_rate
with tf.variable_scope(name):
# We create the placeholders
# *state_size means that we take each elements of state_size in tuple hence is like if we wrote
# [None, 84, 84, 4]
self.inputs_ = tf.placeholder(tf.float32, shape=[state_size[1], state_size[0]], name="inputs")
self.actions_ = tf.placeholder(tf.float32, [None, self.action_size], name="actions_")
# Remember that target_Q is the R(s,a) + ymax Qhat(s', a')
self.target_Q = tf.placeholder(tf.float32, [None], name="target")
self.fc = tf.layers.dense(inputs = self.inputs_,
units = 100,
activation = tf.nn.elu,
kernel_initializer=tf.contrib.layers.xavier_initializer(),
name="fc1")
self.output = tf.layers.dense(inputs = self.fc,
kernel_initializer=tf.contrib.layers.xavier_initializer(),
units = self.action_size,
activation=None)
# Q is our predicted Q value.
self.Q = tf.reduce_sum(tf.multiply(self.output, self.actions_))
# The loss is the difference between our predicted Q_values and the Q_target
# Sum(Qtarget - Q)^2
self.loss = tf.reduce_mean(tf.square(self.target_Q - self.Q))
self.optimizer = tf.train.AdamOptimizer(self.learning_rate).minimize(self.loss)
Ошибка, которая является проблемой:
tensorflow.python.framework.errors_impl.FailedPreconditionError: Attempting to use uninitialized value DQNetwork/fc1/kernel
[[{{node DQNetwork/fc1/kernel/read}}]]
А вот и журнал ошибок: (немного извините, я включил предупреждения)
