Hello,
I am able to install earlier TF(Tensorflow) versions by following the instructions mentioned here: Installing TensorFlow for Jetson Platform :: NVIDIA Deep Learning Frameworks Documentation
When will NVIDIA release the .whl for TF2.0? Cant find one here yet: https://developer.download.nvidia.com/compute/redist/jp/v42/tensorflow-gpu/
Thanks!
Hi,
We don’t have an v2.0 official TensorFlow package yet.
The latest package for Jetson is v1.14.0.
Although there is no available prebuilt data, you can still build it from source on your own.
Here is related topic which can give you some ideas:

Thanks.
Hi,
Missed to see this comment earlier.
Yes, that’s what i went ahead and did. Successfully, built the tensorflow-2.0 on Jetson TX2.
Ubuntu: 18.04
CUDA: 10.0
Tensorrt: 5.1
Python: 3.6.8 {NOTE: I used a virtual env as i was experimenting with different version}
Tensorflow: 2.0.0rc0 (From Github source: https://github.com/tensorflow/tensorflow/tree/r2.0)
Bazel: 26.1 (https://github.com/bazelbuild/bazel/releases, https://docs.bazel.build/versions/master/install-ubuntu.html)
Step that worked for me:
Start here → https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html#prereqs
pip3 install -U wheel
bazel build --config=opt --config=cuda --config=nonccl --config=v2 --local_resources 8192,2.0,1.0 //tensorflow/tools/pip_package:build_pip_package
{NOTE: This step can take a lot of time if done on TX2. Cross-compiling is another option but i didn’t do that.}
./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
pip3 install -U /tmp/tensorflow_pkg/tensorflow-2.0.0rc0-cp36-cp36m-linux_aarch64.whl
Hope it helps someone who is trying the same!

Hey @srkm009, how did you compile Bazel 0.26.1? Did it work directly out of the box or did you have to do anything “special” for that?
Hi @klein.shaked:
Yes, as far as i remember it worked out-of-the-box. I just followed the instructions given here: Installing Bazel on Ubuntu - Bazel main to build it from the source.
It is important that you have to check for the bazel version that works best with the Tensorflow’s version etc. Sometimes, the latest bazel version may be too much for TF and might require down-grade etc.
Hey @srkm009
Which gcc did you use?
I’m using
gcc --version
gcc (Ubuntu/Linaro 7.4.0-1ubuntu1~18.04.1) 7.4.0

any ideas?
@klein.shaked, according to the tensorflow compatibility website, I would try a lower version of gcc.
You should be able to specify the path of your lower gcc-7 version while running ./configure
In case this is useful to anyone, I’ve found that you can build just about anything for the Jetsons on AWS arm64 instances (which are only available in the US East (Ohio) region). It’s much faster, and I wouldn’t dream of trying to build anything directly on a Jetson after getting this working.
Here’s a repo I made that does this for opencv: GitHub - vincilab/build-arm-opencv
I’ve also built Tensorflow 1.15.0 the same way.
Hi,
The above examples are for CPU build which is not using the GPU of jetson. Has anyone compiled tensorflow-gpu 2.0 for Jetson? Is tensorflow-gpu 2.0 still not available for Jetson? Again i don’t want to tensorflow-lite because it doesn’t support all the functions.
Thanks
Ashik
What is the reason that you say it’s only CPU and not using the GPU of the Jetson?
I’m asking because I have built TF2 for ARM on Xavier and when I used some code examples it seemed to behave as expected. Maybe I missed something?
Thank you
TF 1.15+ should have GPU support baked into the main tensorflow package: Release TensorFlow 1.15.0 · tensorflow/tensorflow · GitHub
— Srkm009 used the following command “pip3 install -U /tmp/tensorflow_pkg/tensorflow-2.0.0rc0-cp36-cp36m-linux_aarch64.whl” — it clearly says cpu.
— And according my understanding tensorflow is written for x86 integrated with gpu or tpu. On the other hand jetson has arm core. So does it compile properly for jetson with integrated gpu, since it uses arm core?.
— They have released tensorflow-lite as the official version of tensorflow for arm type of computer. they also release tensorflow lite - gpu delegate for arm with gpu processor(Mobile gpu-- mali).
— So my question is why their is tensorflow lite version(arm64) if tensorflow compiles works for arm64? if we compile tensorflow-gpu 2.0 for jetson will it work? how do you test whether the tf-gpu works on it and has a optimum performance?
I may be wrong here but i’m just trying to understand
Hi,
We have released a TensorFlow v2.0 package for Jetson.
Please reflash your device with JetPack4.3 and install TensorFlow with the command here:
https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html
Thanks.
Does it include the C library support as well? Or is it only for Python3?
The reason I’m asking is because we have 3 different use cases:
Hi,
Thank you so much. I install tensorflow 2.1.0 on TX2.
I am trying to build tensorflow2.0.0 on tx2. below are the details.
System information
Describe the current behavior
when I try running sample application it is crashing. With error logs as “CUDA runtime implicit initialization on GPU:0 failed. Status: unknown error”
Describe the expected behavior
it should start a session.
Standalone code to reproduce the issue
Sample Code
#include <tensorflow/core/platform/env.h>
#include <tensorflow/core/public/session.h>
#include <iostream>
using namespace std;
using namespace tensorflow;
int main()
{
Session* session;
Status status = NewSession(SessionOptions(), &session);
if (!status.ok()) {
cout << status.ToString() << "\n";
}
session->Close();
cout << "Session successfully created.\n";

I am very new to tensorflow and cuda programming both …not sure what is going on. Appreciate the help.
Hi harendra,
Please refer to TensorFlow for Jetson TX2! and try with the latest JetPack 4.4 GA.
If issue still present, please open a new topic.
Thanks
I have upgraded to jetpack4.5. and now I could run this program. thanks!
But my requirement is to run application inside docker on tx2. How to install cuda, cudnn and related libraries inside docker container.
I tried the following.
Eagerly waiting for the image name.
Thanks,
Harendra
Hi harendra,
Please help to open a new topic for your issue. Thanks
