Seriously, is there any official manual for setting the machine?
I’ve reinstalled for 30 times for installing librosa, llvm packages.
And now, tensorflow is not working !!!
Hi,
What is the problem do you meet when installing TensorFlow?
We have a prebuilt package for TensorFlow and you should be able to install it with the command here:
https://devtalk.nvidia.com/default/topic/1048776/jetson-nano/official-tensorflow-for-jetson-nano-/
We don’t include the installation steps of third-party library into our document but you can find some information here:
[url]Jetson Nano - eLinux.org
Thanks.
me too, I have read and followed the following articles from krstyle03v.

jetson nano is not working, when installing libroa, llvm pacakges.
I did a lot of repetition, like manual build of llvm-7 but it still not workig.
please help and teach me and krstyle03v.
Hi,
librosa and llvm don’t support ARM platform.
It’s recommended to check with the company if there is an official release in the future.
Thanks.
I installed librosa 0.6.1 with llvmlite 7.0.1 guided by Redirecting to Google Groups
However, the following error occurs when import librosa, like Unable to find target for this triple (no targets are registered).
How can I solve it?
Thank you.
