问题描述
限时送ChatGPT账号..我需要帮助从在 datalab 上运行的 tensorflow 中 luanching tensorboard,我的代码如下(所有内容都在数据实验室中):
I need help in luanching tensorboard from tensorflow running on the datalab, My code is the followings (everything is on the datalab):
import tensorflow as tf
with tf.name_scope('input'):
print ("X_np")
X_np = tf.placeholder(tf.float32, shape=[None, num_of_features],name="input")
with tf.name_scope('weights'):
print ("W is for weights & - 15 number of diseases")
W = tf.Variable(tf.zeros([num_of_features,15]),name="W")
with tf.name_scope('biases'):
print ("b")
#todo:authemate for more diseases
b = tf.Variable(tf.zeros([15]),name="biases")
with tf.name_scope('layer'):
print ("y_train_np")
y_train_np = tf.nn.softmax(tf.matmul(X_np,W) + b)
with tf.name_scope('correct'):
print ("y_ - placeholder for correct answer")
y_ = tf.placeholder(tf.float32, shape=[None, 15],name="correct_answer")
with tf.name_scope('loss'):
print ("cross entrpy")
cross_entropy = -tf.reduce_sum(y_*tf.log(y_train_np))
# % of correct answers found in batch
print("is correct")
is_correct = tf.equal(tf.argmax(y_train_np,1),tf.argmax(y_,1))
print("accuracy")
accuracy = tf.reduce_mean(tf.cast(is_correct,tf.float32))
print("train step")
train_step = tf.train.GradientDescentOptimizer(0.01).minimize(cross_entropy)
# train data and get results for batches
print("initialize all varaible")
init = tf.global_variables_initializer()
print("session")
sess = tf.Session()
writer = tf.summary.FileWriter("logs/", sess.graph)
init = tf.global_variables_initializer()
sess.run(init)
!tensorboard --logdir=/logs
输出是:在端口 6006 上启动 TensorBoard 41(您可以导航到 http://172.17.0.2:6006)
the output is: Starting TensorBoard 41 on port 6006 (You can navigate to http://172.17.0.2:6006)
然而,当我点击链接时,网页是空的

请让我知道我错过了什么.我期待看到图表.稍后我想生成更多数据.任何建议表示赞赏.
Please let me know what I am missing. I am expecting to see the graph. later i would like to generate more data. Any suggestion is appreciated.
非常感谢!
推荐答案
如果你使用的是datalab,你可以使用tensorboard如下:
If you are using datalab, you can use tensorboard as below:
from google.datalab.ml import TensorBoard as tb
tb.start('./logs')

这篇关于从谷歌云数据实验室启动张量板的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
