Pip3 warning

When I use pip3:

What can i do?

nano@nano-desktop:~/Desktop$ pip3 install --upgrade pip3

Collecting pip3
ERROR: Could not find a version that satisfies the requirement pip3 (from versions: none)

You should consider upgrading via the ‘pip install --upgrade pip’ command.

Hi,

This is a harmless warning.
The log indicates that you don’t have permission for ‘/home/nano/.cache/pip/http’.

If you want to upgrade pip3, please use this command instead:

pip3 install --upgrade <b>pip</b>

Thanks.

I guess this has been introduced by the latest Jetpack 4.2.2.

The TERMINAL window of the SDK Manager when installing JetPack 4.2.2 showed the followings:

17:46:53 INFO : TensorFlow : sudo pip3 install -U pip
17:46:53 INFO : TensorFlow : sudo pip3 install -U numpy grpcio absl-py py-cpuinfo psutil portpicker six mock requests gast h5py astor termcolor protobuf keras-applications keras-preprocessing wrapt google-pasta

The problem is pip3 was executed as sudo without specifying/disabling a cache directory, which makes a cache directory of pip at the default location, in the user home directory, as root. That forces us to use sudo for further pip operations or to specify a different cache directory.

It is not a big deal, but could be confusing.

Thanks buddy, I tried to chmod 777 -R /home/nano ,it seems that it helps.

Thanks, I have updated it.

jetbot@jetbot:~$ sudo pip3 install Jetson.GPIO
