Could you help to fix it?

What is your host operating system, and what version, and what version of Python are you running?

hi， I‘m working on Jetson Nano, jetpack 4.6, and python 3.7.5. The good news is, it's succeeded after I try many times. Maybe it's network issues.

Hola comunidad quisisera si me pueden ayudar con este error no se que hacer se los agradeceria de corazon estoy utilizando jetpack 4.6

You will need to upgrade to Python 3.7 to use the latest version of the library since it uses Blinka 7.0. You could use an older version of the library if you don't want to upgrade.

podría orientarme de como hacerlo, se lo agradecería mucho un abrazo

vale ya pude solucionar el error, ahora el problema que tengo es que no puedo instalar opencv para esa version de python de 3.7 y con la anterior version 3.6.9 si lo habia podido instalar con el comando sudo apt-get install python3-opencv, pero ahora no con la nueva version
