How can I use display device in GCP -linux?

Question

I`m using GCP. Boot Image: c3-deeplearning-tf-1-14-cu100-20191004

Debian GNU/Linux 9.11 (stretch) (GNU/Linux 4.9.0-11-amd64 x86_64\n)

Error message: _tkinter.TclError: no display name and no $DISPLAY environment variable

I wanna use display device.

https://cloud.google.com/compute/docs/instances/enable-instance-virtual-display?hl=en

I saw this docs. But, there is only window-server solution.

Could I get some help for running tkinter in linux-server?

If I understand what you want to achieve it's to use a remote desktop. For this you must follow this steps:

Ssh into your instance

Install the Debian Linux Chrome Remote Desktop package

wget https://dl.google.com/linux/direct/chrome-remote-desktop_current_amd64.deb

Update the package manager data:

sudo apt update.

Install the package and its dependencies

sudo dpkg --install chrome-remote-desktop_current_amd64.deb
sudo apt install --assume-yes --fix-broken

Install either XCFE or Cinnnamon

Connect to the instance using the Chrome Remote Desktop web site

I would advise you to take a look at the Official Documentation for further referencing
