Installing TensorFlow on Raspberry Pi 3 (and probably 2 as well)
If you find the binaries and instructions in this repository useful, please consider donating to help keep this repository maintained. It takes hours of work to compile each new version of TensorFlow, in addition to time spent responding to issues and pull requests.
We did it! It took a lot of head-banging and several indirect passings-of-the-torch, but we finally got TensorFlow compiled and running properly on the Raspberry Pi! Hopefully this will enable more hardware-based machine learning projects, as well as making the distributed aspects of TensorFlow more accessible.
Installing from Pip
Note: These are unofficial binaries (though built from the minimally modified official source), and thus there is no expectation of support from the TensorFlow team. Please don't create issues for these files in the official TensorFlow repository.
This is the easiest way to get TensorFlow onto your Raspberry Pi 3. Note that currently, the pre-built binary is targeted for Raspberry Pi 3 running Raspbian 8.0 ("Jessie"), so this may or may not work for you.
First, install the dependencies for TensorFlow:
sudo apt-get update # For Python 2.7 sudo apt-get install python-pip python-dev # For Python 3.3+ sudo apt-get install python3-pip python3-dev
Next, download the wheel file from this repository and install it:
# For Python 2.7 wget https://github.com/samjabrahams/tensorflow-on-raspberry-pi/releases/download/v0.12.1/tensorflow-0.12.1-cp27-none-linux_armv7l.whl sudo pip install tensorflow-0.12.1-cp27-none-linux_armv7l.whl # For Python 3.3+ wget https://github.com/samjabrahams/tensorflow-on-raspberry-pi/releases/download/v0.12.1/tensorflow-0.12.1-cp34-cp34m-linux_armv7l.whl sudo pip3 install tensorflow-0.12.1-cp34-cp34m-linux_armv7l.whl
Finally, we need to reinstall the
mock library to keep it from throwing an error when we import TensorFlow:
# For Python 2.7 sudo pip uninstall mock sudo pip install mock # For Python 3.3+ sudo pip3 uninstall mock sudo pip3 install mock
And that should be it!
This section will attempt to maintain a list of remedies for problems that may occur while installing from
"tensorflow-0.12.1-cp27-none-linux_armv7l.whl is not a supported wheel on this platform."
This wheel was built with Python 2.7, and can't be installed with a version of
pip that uses Python 3. If you get the above message, try running the following command instead:
sudo pip2 install tensorflow-0.12.1-cp27-none-linux_armv7l.whl
Vice-versa for trying to install the Python 3 wheel. If you get the error "tensorflow-0.12.1-py3-none-any.whl is not a supported wheel on this platform.", try this command:
sudo pip3 install tensorflow-0.12.1-cp34-cp34m-linux_armv7l.whl
Building from Source
If you aren't able to make the wheel file from the previous section work, you may need to build from source. Additionally, if you want to use features that have not been included in an official release, such as the initial distributed runtime, you'll have to build from source. Don't worry, as we've figured out most of the quirks of getting it right. The guide will be updated as needed to be as correct as possible.
See the step-by-step guide here. Warning: it takes a while.
Non-Raspberry Pi Model 3 builds
There are numerous single-board computers available on the market, but binaries and build instructions aren't necessarily compatible with what's available in this repository. This is a list of resources to help those with non-RPi3 (or RPi 2) computers get up and running:
Or: people who did most of the actual work.
While we may have just gotten RPi TensorFlow compiled properly in the last few days (with the most recent grunt work done by myself and @petewarden), this effort has been going on for almost as long as TensorFlow has been open-source, and involves work that spans multiple months in separate codebases. This is an incomprehensive list of people and their work I ran across while working on this.
The majority of the source-building guide is a modified version of these instructions for compiling TensorFlow on a Jetson TK1. Massimiliano, you are the real MVP. Note: the TK1 guide was updated on June 17, 2016
@vmayoral put a huge amount of time and effort trying to put together the pieces to build TensorFlow, and was the first to get something close to a working binary.
A bunch of awesome Googlers working in both the TensorFlow and Bazel repositories helped make this possible. In no particular order: @vrv, @damienmg, @petewarden, @danbri, @ulfjack, @girving, and @nlothian
Issue threads of interest:
- Initial issue for building Bazel on ARMv7l
- First thread about running TensorFlow on RPi
- Parallel thread on building TensorFlow on ARMv7l
- This is where the most recent conversation is located
