Tensorboard gives empty page

[yitzhak....@gmail.com]

Hi, trying to visualize stuff with tensorboard (I am using keras) the browser doesn't show anything. Here are the relevant lines from my Train.py

tbCallBack = keras.callbacks.TensorBoard(log_dir='./Graph', histogram_freq=0, write_graph=True, write_images=True)
train_hist=model.fit(x_train, y_train,
          batch_size=batch_size,
          epochs=epochs,
          validation_data=(x_test, y_test),
          callbacks=[tbCallBack])

Now the training itself works fine. it shows the iterations trough the epochs etc. Now while the Train.py is running I run

$ tensorboard --logdir=./Graph

I see some event file being created in the ./Graph directory and I tensorboard gives me a link for the browser. However when I open it, it is empty. I tried it both in Chrome and in Firefox.

I was running to this issue recently and found that it had to do with allowing Chrome to load javascript/images/popups for tensorboard (click on the information icon next to the url). Haven't narrowed down the problem any further however. Additionally, if you have another browser like Safari, try to open tensorboard on there and see if it works (it did for me).

the issue is solved now. here it is:

Not sure if this is necessary (or already done) via Keras, but when I use tensorboard with tensorflow, I sometimes need to have a manual "flush" the writer to see the results

e.g., as in

with tf.Session(graph=g) as sess:

sess.run(tf.global_variables_initializer())

file_writer = tf.summary.FileWriter(logdir='logs/1', graph=g)

for i in range(5):
result, summary = sess.run([update_tf_x, merged_summary],
feed_dict={some_value: i})

file_writer.add_summary(summary=summary, global_step=i)
file_writer.flush()


Just an idea that this could maybe be an issue here?
