Is there any way to use TensorBoard when training a TensorFlow model on Google Colab?


EDIT: You probably want to give the official %tensorboard magic a go, available from TensorFlow 1.13 onward.


Prior to the existence of the %tensorboard magic, the standard way to achieve this was to proxy network traffic to the Colab VM using ngrok. A Colab example can be found here.

These are the steps (the code snippets represent cells of type "code" in colab):

  1. Get TensorBoard running in the background. Inspired by this answer.

    LOG_DIR = '/tmp/log'
    get_ipython().system_raw(
        'tensorboard --logdir {} --host 0.0.0.0 --port 6006 &'
        .format(LOG_DIR)
    )
    
  2. Download and unzip ngrok. Replace the link passed to wget with the correct download link for your OS.

    ! wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip
    ! unzip ngrok-stable-linux-amd64.zip
    
  3. Launch ngrok background process...

    get_ipython().system_raw('./ngrok http 6006 &')
    

    ...and retrieve public url. Source

    ! curl -s http://localhost:4040/api/tunnels | python3 -c \
        "import sys, json; print(json.load(sys.stdin)['tunnels'][0]['public_url'])"
    

Quick guide to run TensorBoard in Google Colab, Google Colab is a free to use Jupyter notebook, that allows you to use free Nvidia Tesla T4 GPUs and 12 GB of RAM which you can use it up to 12 hours in row. You learned how to run TensorBoard on a Google Colab notebook and access it on your local machine by leveraging the free ngrok tunneling service. One bonus, alternatively you can run the following code in Colab to use localtunnel instead of ngrok.


Here's an easier way to do the same ngrok tunneling method on Google Colab.

!pip install tensorboardcolab

then,

from tensorboardcolab import TensorBoardColab, TensorBoardColabCallback

tbc=TensorBoardColab()

Assuming you are using Keras:

model.fit(......,callbacks=[TensorBoardColabCallback(tbc)])

TensorBoard for TensorFlow running on Google Colab using tensorboardcolab. This uses ngrok internally for tunnelling.

  1. Install TensorBoardColab

!pip install tensorboardcolab

  1. Create a tensorboardcolab object

tbc = TensorBoardColab()

This automatically creates a TensorBoard link that can be used. This Tensorboard is reading the data at './Graph'

  1. Create a FileWriter pointing to this location

summary_writer = tbc.get_writer()

tensorboardcolab library has the method that returns FileWriter object pointing to above './Graph' location.

  1. Start adding summary information to Event files at './Graph' location using summary_writer object

You can add scalar info or graph or histogram data.

Using TensorBoard in Notebooks, Tesla K80 GPU it also gives you a total of 12 GB of ram , and you can use it up to 12 hours in row . In this post I’ll show you two ways you can visualize your PyTorch model training when using Google Colab. The first uses the new Jupyter TensorBoard magic command, and the second uses the library


I tried but did not get the result but when used as below, got the results

import tensorboardcolab as tb
tbc = tb.TensorBoardColab()
after this open the link from the output.
import tensorflow as tf
import numpy as np
Explicitly create a Graph object
graph = tf.Graph()
with graph.as_default()

Complete example :

with tf.name_scope("variables"):
    # Variable to keep track of how many times the graph has been run
    global_step = tf.Variable(0, dtype=tf.int32, name="global_step")

    # Increments the above `global_step` Variable, should be run whenever the graph is run
    increment_step = global_step.assign_add(1)

    # Variable that keeps track of previous output value:
    previous_value = tf.Variable(0.0, dtype=tf.float32, name="previous_value")

# Primary transformation Operations
with tf.name_scope("exercise_transformation"):

    # Separate input layer
    with tf.name_scope("input"):
        # Create input placeholder- takes in a Vector 
        a = tf.placeholder(tf.float32, shape=[None], name="input_placeholder_a")

    # Separate middle layer
    with tf.name_scope("intermediate_layer"):
        b = tf.reduce_prod(a, name="product_b")
        c = tf.reduce_sum(a, name="sum_c")

    # Separate output layer
    with tf.name_scope("output"):
        d = tf.add(b, c, name="add_d")
        output = tf.subtract(d, previous_value, name="output")
        update_prev = previous_value.assign(output)

# Summary Operations
with tf.name_scope("summaries"):
    tf.summary.scalar('output', output)  # Creates summary for output node
    tf.summary.scalar('product of inputs', b, )
    tf.summary.scalar('sum of inputs', c)

# Global Variables and Operations
with tf.name_scope("global_ops"):
    # Initialization Op
    init = tf.initialize_all_variables()
    # Collect all summary Ops in graph
    merged_summaries = tf.summary.merge_all()

# Start a Session, using the explicitly created Graph
sess = tf.Session(graph=graph)

# Open a SummaryWriter to save summaries
writer = tf.summary.FileWriter('./Graph', sess.graph)

# Initialize Variables
sess.run(init)

def run_graph(input_tensor):
    """
    Helper function; runs the graph with given input tensor and saves summaries
    """
    feed_dict = {a: input_tensor}
    output, summary, step = sess.run([update_prev, merged_summaries, increment_step], feed_dict=feed_dict)
    writer.add_summary(summary, global_step=step)


# Run the graph with various inputs
run_graph([2,8])
run_graph([3,1,3,3])
run_graph([8])
run_graph([1,2,3])
run_graph([11,4])
run_graph([4,1])
run_graph([7,3,1])
run_graph([6,3])
run_graph([0,2])
run_graph([4,5,6])

# Writes the summaries to disk
writer.flush()

# Flushes the summaries to disk and closes the SummaryWriter
writer.close()

# Close the session
sess.close()

# To start TensorBoard after running this file, execute the following command:

Here is how you can display your models inline on Google Colab. Below is a very simple example that displays a placeholder:

from IPython.display import clear_output, Image, display, HTML
import tensorflow as tf
import numpy as np
from google.colab import files

def strip_consts(graph_def, max_const_size=32):
    """Strip large constant values from graph_def."""
    strip_def = tf.GraphDef()
    for n0 in graph_def.node:
        n = strip_def.node.add() 
        n.MergeFrom(n0)
        if n.op == 'Const':
            tensor = n.attr['value'].tensor
            size = len(tensor.tensor_content)
            if size > max_const_size:
                tensor.tensor_content = "<stripped %d bytes>"%size
    return strip_def

def show_graph(graph_def, max_const_size=32):
    """Visualize TensorFlow graph."""
    if hasattr(graph_def, 'as_graph_def'):
        graph_def = graph_def.as_graph_def()
    strip_def = strip_consts(graph_def, max_const_size=max_const_size)
    code = """

    iframe = """
        <iframe seamless style="width:1200px;height:620px;border:0" srcdoc="{}"></iframe>

"""Create a sample tensor"""

Currently, you cannot run a Tensorboard service on Google Colab the way you run it locally. Also, you cannot export your entire log to your Drive via something like summary_writer = tf.summary.FileWriter('./logs', graph_def=sess.graph_def) so that you could then download it and look at it locally.
