TensorFlow on NVIDIA Jetson TX2 Development Kit

Note: There is an updated article for installing TensorFlow 1.3 on the Jetson TX2 running L4T 28.1. The repository for these scripts has been updated. Please make sure to checkout the tagged version for L4T 27.1 in this article.

In this article, we will work through installing TensorFlow v1.0.1 on the Jetson TX2. Looky here:


TensorFlow is one of the major deep learning systems. Created at Google, it is an open-source software library for machine intelligence. The Jetson TX2 ships with TensorRT, which is the run time for TensorFlow. TensorRT is what is called an “Inference Engine“, the idea being that large machine learning systems can train models which are then transferred over and “run” on the Jetson.

However, some people would like to use the entire TensorFlow system on a Jetson. This has been difficult for a few reasons. The first reason is that TensorFlow binaries aren’t generally available for ARM based processors like the Tegra TX2. The second reason is that actually compiling TensorFlow takes a larger amount of system resources than is normally available on the Jetson TX2. The third reason is that TensorFlow itself is rapidly changing (it’s only a year old), and the experience has been a little like building on quicksand.

In this article, we’ll go over the steps to build TensorFlow v1.0.1 on the Jetson TX2. This will take about three hour and a half hours to build.

Note: Please read through this article before starting installation. This is not a simple installation, you may want to tailor it to your needs.


This article assumes that Jetson 3.0 is used to flash the Jetson TX2. At a minimum, install:

  • L4T 27.1 an Ubuntu 16.04 64-bit variant (aarch64)
  • CUDA 8.0
  • cuDNN 5.1.10

TensorFlow will use CUDA and cuDNN in this build.

In order to get TensorFlow to compile on the Jetson TX2, a swap file is needed for virtual memory. Also, a good amount of disk space ( > 6 GB ) is needed to actually build the program. If you’re unfamiliar with how to set the Jetson TX2 up like that, the procedure is similar to that as described in the article: Jetson TX1 Swap File and Development Preparation.

There is a repository on the JetsonHacks account on Github named installTensorFlowTX2. Clone the repository and switch over to that directory.

$ git clone https://github.com/jetsonhacks/installTensorFlowTX2
$ cd installTensorFlowTX2

$ git checkout vL4T27.1TF1.0


There is a convenience script which will install the required prerequisites such as Java and Bazel. The script also patches the source files appropriately for ARM 64.

$ ./installPrerequisites.sh

From the video installation of the prerequisites takes a little over 30 minutes, but will depend on your internet connection speed.

Building TensorFlow

First, clone the TensorFlow repository and patch for Arm 64 operation:

$ ./cloneTensorFlow.sh

then setup the TensorFlow environment variables. This is a semi-automated way to run the TensorFlow configure.sh file. You should look through this script and change it according to your needs. Note that most of the library locations are configured in this script. The library locations are determined by the JetPack installation.

$ ./setTensorFlowEV.sh

We’re now ready to build TensorFlow:

$ ./buildTensorFlow.sh

This will take a couple of hours. After TensorFlow is finished building, we package it into a ‘wheel’ file:

$ ./packageTensorFlow.sh

The wheel file will be in the $HOME directory, tensorflow-1.0.1-cp27-cp27mu-linux_aarch64.whl


Pip can be used to install the wheel file:

$ pip install $HOME/tensorflow-1.0.1-cp27-cp27mu-linux_aarch64.whl


You can go through the procedure on the TensorFlow installation page: Tensorflow: Validate your installation

Validate your installation Validate your TensorFlow installation by doing the following:

Start a terminal.
Change directory (cd) to any directory on your system other than the tensorflow subdirectory from which you invoked the configure command.
Invoke python:

$ python

Enter the following short program inside the python interactive shell:

>>> import tensorflow as tf
>>> hello = tf.constant(‘Hello, TensorFlow!’)
>>> sess = tf.Session()
>>> print(sess.run(hello))

If the Python program outputs the following, then the installation is successful and you can begin writing TensorFlow programs.

Hello, TensorFlow!”


So there you have it. Building TensorFlow is quite a demanding task, but hopefully some of these scripts may make the job a little bit simpler.


  1. In your tensorflow patch script, the first patch fails. I believe the BUILD file has been updated since r0.11 and it looks like you are using the same or similar patch file. Though this does not seem to damage the rest of the build.

    • Good catch! Looking back at my notes, I had marked that I needed to remove it, but with there’s three hours between builds I must have forgot about it. As you noted, the patch doesn’t do anything, so everything should work. I also have a note that questions the two patches that followed. They are needed on the TX1. I wasn’t sure if it applied for the TX2, so I just left them in. Thanks for finding this, and thanks for reading!

  2. Hi there,

    Thanks for the detailed tutorial! I’m a bit of a noob with all this, so your video is very helpful! I’m running into an error when running packageTensorFlow.sh. Here’s the error:

    can’t copy ‘tensorflow/contrib/image/ops/gen_image_ops.py’: doesn’t exist or not a regular file

    Any thoughts on what might be the issue? I looked in that directory and the file indeed isn’t there.

    Thanks again!

    • It sounds like your build is incomplete. The referenced file is generated during the build process. You can try the ‘buildTensorFlow.sh’ script again and look for any issues that may have cropped up. Thanks for reading!

  3. I get the following error when running ./installPrerequisites.sh
    cannot stat output/bazel

    I’m using Jetson TX2 with Jetpack 3.1 as mentioned in the preperation section of this blog.

  4. Hello ! Thank you very much for this article. Is there an update for JetPack 3.2?
    L4T R28.2
    CUDA 9.0
    cuDNN 7.0.5 RC

    Or should I use a mechanism to install TensorFlow? (Virtualenv/Anaconda)

    Thank you in advance for you help!
