How to install TensorFlow and Spicy into my Jetson nano ?
I have 2 SD cards and images. One for Hello! AI world, the another is for headless getting started with AI class.

I’m current working on headless mode with SD card image for “getting started with AI on Jetson Nano”, how can I install TensorFlow and Spicy?

Thanks

Hi,

You can install TensorFlow with the instructiuon shared in this document:

Spicy can be installed via this command:

pip3 install scipy

Please noticed that both installations take hours to finish.

Thanks.

Hi,

It did not work. Please see following:

dlinano@jetson-nano:~$ pip3 install scipy

My questions:
I had completed the class “getting started AI with Jetson nano” .
(1) For installation of Tensorflow/Scipy, can I use the same image SD card for the headless mode in the class “getting started AI with Jetson nano” ?
(2) Why I got the error message during install (described as above)?

Thanks

Can I install “JetPack” in the same SD card using the headless mode in the class “getting started AI with Jetson nano” ? or, I need another new SD card for the image again?

Can you try

$sudo apt-get install python3-scipy

For more details: https://www.scipy.org/install.html#package-manager
Once it installs:

$python3
>> import scipy

Hi,

It looks like there are something wrong on your networks.
Could you try to access “[url]http://ports.ubuntu.com/ubuntu-ports[/url]” with browser to see if any problem?

Thanks.
