Introduction to Chrome Tracing
Chrome Tracing is a powerful tool that allows you to visualize the performance of your web applications. With Chrome Tracing, you can see how your application interacts with the browser, and identify bottlenecks that may be slowing down your application. You can also use Chrome Tracing to profile the performance of your TensorFlow models, and identify areas where your models are not performing optimally.
What is TensorFlow?
TensorFlow is a powerful tool for machine learning that can be used to train models to recognize patterns in data. Chrome Tracing is a feature of the Chrome web browser that can be used to collect performance data about web pages and applications. By combining these two technologies, it is possible to collect detailed information about the way TensorFlow models are being used, and how they are performing. This can be used to optimize the training of models, and to improve the overall performance of machine learning applications.
Setting up Chrome Tracing
Performance tracing is a powerful tool for understanding the behavior of web applications. The Chrome Developer Tools offer built-in performance tracing that can be used to collect and analyze data about how a web application is running.
TensorFlow is a open-source machine learning library that can be used totrain and debug machine learning models. The TensorFlow Debugger (tfdbg) is a tool that can be used to visualize the execution of TensorFlow programs.
The tfdbg package includes a Chrome Tracing exporter that can be used to generate performance trace files that can be analyzed with the Chrome Developer Tools.
In order to use the Chrome Tracing exporter, you must first set up your environment to use it.
Collecting Trace Data
In order to use Chrome Tracing with TensorFlow, you first need to collect trace data from a target application. This can be done using the chrome://tracing tool, which is built into the Google Chrome browser.
To use chrome://tracing, you first need to enable tracing for the target application. You can do this by adding the following flags to the target application’s command line:
–trace-upload-url= /* should be replaced with your own server’s URL */
Once these flags have been set, you can launch the target application and begin tracing by clicking the “Record” button in chrome://tracing. After a few seconds (or longer, if desired), click the “Stop” button to end tracing.
Analyzing Trace Data
Now that you have a generated trace file, you can open it up in the Chrome://tracing tool for analysis. The left column shows each process and thread color-coded by process. You can hover over a region to see what it corresponds to in the flame chart on the right or in the table below. Alternatively, you can click on a region to zoom in on it.
The trace file format allows for custom annotations to be added anywhere in the trace. If you are profiling a TensorFlow graph, then you can use the annotations to help understand what is happening during execution. For example, each node in the graph will be annotated with input/output tensor shapes as well as the device that processed it.
Visualizing Trace Data
In order to get started with visualization, continue reading this page. The first step is to load the libraries needed for this tutorial.
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
from scipy import stats
from sklearn import datasets
from tensorflow.contrib.learn.python import learn
import tensorflow as tf
Optimizing TensorFlow Models
Chrome tracing is a powerful tool that can be used to optimize TensorFlow models. By logging events and timing information during the execution of a TensorFlow graph, you can identify areas where the graph is taking longer than expected to execute. This information can then be used to optimize the graph, improving performance.
TensorFlow Serving is a production-ready open source platform for machine learning serving. It allows you to deploy new algorithms and experiments, while keeping the same server architecture and APIs. In addition to TensorFlow Serving, you can also use your own custom prediction code written in any language.
With TensorFlow Serving, you can keep serving your existing models with no downtime during an experiment or a canary deployment. When you are ready to switch over to the new model, simply change a single parameter in the config file and reload the server.
TensorFlow in the Cloud
TensorFlow is a powerful open source software library for data analysis and machine learning. The project was started by Google Brain in order to bring the benefits of machine learning to as many people as possible. TensorFlow allows you to run your models on either your local computer or in the cloud.
Google Cloud Platform (GCP) offers a managed service called Cloud ML Engine, which allows you to train and deploy your TensorFlow models in the cloud. In this tutorial, we will show you how to use GCP to train and serve a simple TensorFlow model.
First, we will need to create a TensorFlow model. We will use a simple linear regression model for this tutorial. The code for the model is given below:
def linear_regression(x, w, b):
return tf.matmul(x, w) + b
Next, we will need to create some training data. We will use a synthetic dataset for this tutorial. The code for generating the dataset is given below:
x = np.random.uniform(-1, 1, (num_samples, 1))
y = 2 * x + np.random.normal(0, 0.1, (num_samples, 1))
return x, y
Now that we have our model and training data, we are ready to train our model in the cloud using GCP’s Cloud ML Engine service. The code for doing this is given below:
Once the training job has completed, we can deploy our trained model to Cloud ML Engine and serve predictions from it. The code for doing this is given below:
Now that our model is deployed and serving predictions, we can send it some data and see what it predicts. The code for doing this is given below:
As you can see from the above output, our deployed model was able to make predictions that are close to the true values from our synthetic dataset (the blue line).
Now that we’ve learned about Chrome tracing and how it can be used with TensorFlow, let’s take a moment to recap what we’ve covered. First, we learned that Chrome tracing is a performance analysis tool that allows you to collect and visualize performance data from your web applications. Then, we saw how TensorFlow can be used to generate traces for your application, which can then be visualized using thechrome://tracing tool. Finally, we looked at how to use chrome://tracing to profile a simple TensorFlow application.
