Error opening tensorboard

Question

I'm getting an error opening tensorboard. This is my code:

import tensorflow as tf
a = tf.constant(5,name = 'input_a')
b = tf.constant(3,name = 'input_b')
c = tf.multiply(a,b,name='mul_c')
d = tf.add(a,b,name='add_d')
e = tf.add(c,d,name = 'add_e')
with tf.Session() as sess:
    output = sess.run(e)
    print(output)
    writer = tf.summary.FileWriter('path/to/log',tf.get_default_graph())
    writer.close()

This is the command:

tensorboard --logdir=path/to/log  

This is the ERROR:

I got the same error and fixed it. Apparently, there is a problem with html5lib, but mrry's suggestion does not solve it because a message will tell you that you already have the latest version installed.

Instead, run this:

pip install html5lib==1.0b8
