interactive.util.format_task() uses stat.st_birthtime, which doesn't exist on Windows

[cfculhane]

System Information

• OS platform and distribution (e.g. Linux Ubuntu 16.04): Win 10 Pro
• gobbli version: 0.2.2
• Python version: 3.8
• Other information relevant to the problem (GPU model, Docker version, etc):

Description

• When runninggobbli evaluate, gobbli explore during the model loading phase it runs interactive.util.format_task()
• This gets the creation time of the task_dir using Path.stat().st_birthtime
• st_birthtime doesn't exist on windows, so you get an AttributeError , see https://stackoverflow.com/questions/237079/how-to-get-file-creation-modification-date-times-in-python for a discussion
• Instead, on windows you need to call Path.stat().st_ctime

Code for Minimal Reproducible Example

from pathlib import Path
Path(__file__).stat().st_birthtime  # Raises AttributeError
Path(__file__).stat().st_ctime  # Works as expected

Output

AttributeError: 'os.stat_result' object has no attribute 'st_birthtime'

Thanks for the detailed report! Our merging process is a little disrupted right now, so I'm not sure how soon this will be on PyPI, but it's fixed in a branch here, at least.

Fixed in v0.2.3, which I've just pushed out to PyPI.
