問題我最近開始對深度學習感興趣。我抄Tensorflow初級教程中,我得到的語法錯誤和爲什麼發生這種情況,以及如何解決它,所以我可以用我的學習收穫繼續無法運行該腳本我有一個TensorFlow入門教程
from tensorflow.examples.tutorials.mnist import input_data
mnist = input_data.read_data_sets("MNIST_data/", one_hot=True)
import tensorflow as tf
x = tf.placeholder(tf.float32, [None,784])
W = tf.Variable(tf.zeros([784, 10]))
b = tf.Variable(tf.zeros([10]))
y = tf.nn.softmax(tf.matmul(x, W) + b)
#TRAINING
y_ = tf.placeholder(tf.float32, [None, 10])
cross_entropy = tf.reduce_mean(-tf.reduce_sum(y_ * tf.log(y).reduction_indices = [1]
train_step = tf.train.GradientDescentOptimizer(0.5).minimize(cross_entropy)
#(SYNTAX ERROR IN "P" OF TRAIN_STEP)
sess = tf.InteractiveSession()
tf.global_variable_initializer().run()
for _ in range(1000):
batch_xs, batch_ys = mnist.train.next_batch(100)
sess.run(train_step, feed_dict = {x: batch_xs, y_: batch_ys})
#EVALUATION
correct_prediction = tf.equal(tf.argmax(y,1), tf.argmax(y_,1))
accuracy = tf.reduce_mean(tf.cast(correct_prediction, tf.float32))
print(sess.run(accuracy, feed_dict={x: mnist.test.images, y_: mnist.test.labels}))
。
它確實工作! (儘管給出的代碼沒有括號)。另一個問題是關鍵字不能成爲表達式......但是,謝謝! – Kylian
剛剛解決它!!!!偉大的jajaja知道我必須等待30分鐘或更多的結果:) – Kylian
太棒了!祝你好運! – rmeertens
