thread 'main' panicked at 'Could not determine the UTC offset on this system

[follperson]

I've been running this on linux via AWS SageMaker for some experimentation with Twitter hashtags and I think the new releases changed something relating to the simple-logger update. I reverted back to 0.3.3 and everything works.

I really appreciate this implementation tho! it is very quick and efficient for testing out some extreme classification pipelines, thanks for writing it up!

Backtrace

thread 'main' panicked at 'Could not determine the UTC offset on this system. Possible causes are that the time crate does not implement "local_offset_at" on your system, or that you are running in a multi-threaded environment and the time crate is returning "None" from "local_offset_at" to avoid unsafe behaviour. See the time crate's documentation for more information.

Notes

Seems like the same problem as noted here:
ravenclaw900/DietPi-Dashboard#82

[tomtung]

Thanks for raising this issue! I'm currently on vacation and don't have access to my PC. In the meantime, can you help try out the fix from ravenclaw900/DietPi-Dashboard@a3853c2 and see if that solves your issue? If that works, I'll push and release the same fix as soon as I get back.

According to borntyping/rust-simple_logger#52, the easiest thing to do is probably to upgrade simple_logger to the latest version. Will try that.
