I am getting the following error:

Hi,

Please remember to upgrade pip3 first:

sudo pip3 install -U pip

You can find the detail instruction here:
https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html#prereqs

Thanks.

The update broke my pip3 command. I got:

pip3 --version

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main'

I temporarily fixed it by changing a line in ‘/usr/bin/pip3’:

from pip import main

TO

from pip._internal import main

Hi,

You can fix the import error with the following comment. It is a known issue for pip:

Thanks.
