You can try to close the network proxy in the system settings and restart a new terminal to run python app.py

unset all_proxy & unset ALL_PROXY can solve this problem

unset all_proxy & unset ALL_PROXY can solve this problem

Using this method does not make the code run successfully, in my case

You can try to close the network proxy in the system settings and restart a new terminal to run python app.py

If I turn off the proxy in the system settings, I will lose network contact with the outside world and cannot continue to download the data and third-party libraries required for successful operation after running ./app.py.

You can try to download the models manually and put them in corresponding folders with the proxy open, then run app.py without the proxy.
