我有一个似乎在Keras没有直接解决方案的问题。我的服务器在ubuntu 14.04上运行,keras使用后端tensorflow。
问题在于:
我想使用tensorboard绘制直方图,其他训练指标图。 我按照以下程序执行此操作。
我ssh到远程GPU服务器并使用以下命令行启动了tensorboard:
<-
此外,它还生成了以下输出
tensorboard --port 13987 --log==/home/tharun/Desktop/logs
然后我ssh到远程服务器使用以下命令行在该系统上打开firefox
tensorboard --port 13987 --log==/home/tharun/Desktop/logs
/home/tharun/anaconda2/lib/python2.7/site-packages/h5py/__init__.py:34: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters
TensorBoard 0.4.0rc3 at http://sidh-pc:13987 (Press CTRL+C to quit)
在打开的firefox浏览器http://sidh-pc:13987中输入并打开了tensorboard页面。以下信息显示在窗口中。
ssh -X tharun@172.26.175.67 firefox -no-remote
我在链接https://github.com/tensorflow/tensorboard检查了tensorboard readme.txt。然后我在终端输入以下命令并收到输出:
No dashboards are active for the current data set.
Probable causes:
You haven’t written any data to your event files.
TensorBoard can’t find your event files.
If you’re new to using TensorBoard, and want to find out how to add data and set up your event files, check out the README and perhaps the TensorBoard tutorial.
If you think TensorBoard is configured properly, please see the section of the README devoted to missing data problems and consider filing an issue on GitHub.

Log directory: =/home/tharun/Desktop/logs
在检查器模式下运行tensororboard以检查事件文件的内容。
(deep-learning) tharun@sidh-pc:~$
find /home/tharun/Desktop/logs/ | grep tfevents
/home/tharun/Desktop/logs/events.out.tfevents.1516101897.sidh-pc
/home/tharun/Desktop/logs/events.out.tfevents.1516101849.sidh-pc
在下一阶段,运行以下脚本(位于/ home / tharun / Desktop /)以生成更多事件文件并在tensorboard中绘制结果
(deep-learning) tharun@sidh-pc:~$
tensorboard --inspect --logdir /home/tharun/Desktop/logs

张量板窗口的状态没有变化。因此,我重新启动了tensorboard服务器并完成了上述类似的过程。但是firefox中的tensorboard窗口仍显示相同的状态日志:
from keras.models import Sequential
from keras.layers import Dense
import numpy
from keras.callbacks import TensorBoard
from time import time
# fix random seed for reproducibility
numpy.random.seed(7)
# load pima indians dataset
dataset = numpy.loadtxt("pima-indians-diabetes.csv", delimiter=",")
# split into input (X) and output (Y) variables
X = dataset[:,0:8]
Y = dataset[:,8]
# create model
model = Sequential()
model.add(Dense(12, input_dim=8, activation='relu'))
model.add(Dense(8, activation='relu'))
model.add(Dense(1, activation='sigmoid'))
# Compile model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
tensorboard =TensorBoard(log_dir='./logs', histogram_freq=1, batch_size=1, write_graph=True, write_grads=True, write_images=False, embeddings_freq=0, embeddings_layer_names=None, embeddings_metadata=None)
# Fit the model
model.fit(X, Y, epochs=150, batch_size=10, validation_split=0.2, verbose=1, callbacks=[tensorboard])
# evaluate the model
scores = model.evaluate(X, Y)
print("\n%s: %.2f%%" % (model.metrics_names[1], scores[1]*100))
答案 0 :(得分:1)
终端中的以下一行做了伎俩!!目前位于/ home / tharun / Desktop /目录
tensorboard --logdir=./
