Просматривая последний журнал, я вижу OSError: [Errno 9] Неверный файловый дескриптор, который поступает из socket.py (может быть, встроенный?), ищу трассировку, которую я см. werkzueg, выше вижу flask и flask-cors, затем снова werkzeug, и на самом верху:

Я не могу найти что -то не так в этой строке. App.py  существует  в том же каталоге. Даже это не полезно: < /p>
ValueError: signal only works in main thread of the main interpreter
< /code>
Вот пример: < /p>

else:
app.run(host='0.0.0.0', port=8000, debug=True)

Итак, если кто-нибудь знает, что происходит, пожалуйста, помогите
TIA!
