Thanks for your bug report. We appreciate it a lot.

Describe the bug

When running deploy.py on my Windows laptop, I got the warning ""visualize_model" has been skipped" due to os.getenv('DISPLAY') returns None. However, it is impossible that my laptop doesn't have a display device. I guess os.getenv('DISPLAY') cannot work correctly on Windows.

PS: I think besides is_display is not None, args.show should also be checked when deciding whether to call visualization. Even when we are using a server, we need visualize_model to write the output to a file.

Reproduction

Run any script with deploy.py on Windows.
