[CLI] UnicodeEncodeError: 'ascii' codec can't encode character '\u2b50'

Description Using wandb through a SLURM job, I get an UnicodeEncodeError on some nodes on which code is being executed (not all). I narrowed down the issue and the character that raises the error (not obvious from the original message) is the “white medium star”: \u2b50.

How to reproduce Minimal script allowing to reproduce error: test.py

#!/usr/bin/env python
import wandb
wandb.init(reinit=True)
wandb.init(reinit=True)

launched with (SLURM command):

srun --pty test.py

Environment

• OS: Ubuntu 20.04
• Environment: anaconda
• Python 3.6.12
• WandB version: wandb-0.10.15

The above exception was the direct cause of the following exception:

I have the same problem, the solution proposed by Gabriel works for me. Thanks mate!

[gabriel-vanzandycke]

a quick fix is to change the following in the final block of _log defined in wandb/errors/term.py:

        try:
            click.echo(line, file=sys.stderr, nl=newline)
        except:
            click.echo(line.encode(), file=sys.stderr, nl=newline)
