I want to know, when Tensorflow 1.x will release for jetpack 4.4?

Hi @LoveNvidia, TF 1.x will be posted shortly (this week), please stay tuned.

The TensorFlow wheels for JetPack 4.4 Developer Preview have now been posted, you can find them here:


I am trying to run the CUDA and VisionWorks samples on the JetPack 4.4 release but am having trouble finding them. Are they not available on there?

Nevermind. I had flashed Jetson 4.4 via the command line and didn’t realize I did not include all the SDK components (like Cuda and VisionWorks). I reflashed using SDK Manager and that included all the SDK components.

Just a tip: Adding optional packages does not require flashing again. Extra packages are added over ssh from a fully/normally booted Jetson. You can uncheck the flash part of running JetPack/SDKM.

When will JetPack be supported on Ubuntu 20.04 host machine? I want to flash a Jetson TX2 and have since upgraded to Ubuntu 20.04.
