Merhabalar,
Bu yazımda sizlere Google Colab üzerine VNC Server kurulumunu anlatacağım. İyi okumalar.
Öncelikle bir colab hesabı açıyorsunuz ardından yeni bir dosya oluşturup bu kodları üzerine yapıştırın.

Ardından NGROK üzerinden bir Free hesap açıp ardından Your Authtoken'i kopyalıyorsunuz. Kodu başlatmadan önce Çalışma Zamanı > Çalışma Zamanı türünü değiştir kısmından GPU'yu seçiyoruz. Seçtikten sonra başlatıyoruz ve ilk input'a NGROK Authtoken'i yazıyoruz. Ardından server seçiyoruz ve yüklüyoruz. Önerim us - United States (Ohio) veya eu - Europe (Frankfurt) kurmaktır.
VNC Server bilgileriniz kurulum ardından konsolda yansıyacaktır. Bu bilgilerle VNC Viewer benzeri programlarla server'a bağlanabilirsiniz.
