Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!

"""
Given a dictionary, transform it to a string. Then byte encode that string. Then base64 encode it and since this will go
on a url, use the urlsafe version. Then decode the byte string so that it can be else where.
"""
data = base64.urlsafe_b64encode(json.dumps({'a': 123}).encode()).decode()

# And the decode is just as simple...
data = json.loads(base64.urlsafe_b64decode(query_param.encode()).decode())
# Byte encode the string, base64 decode that, then byte decode, finally transform it to a dictionary

This is a simple example of how to use loguru in your flask application

Just create a new InterceptHandler and add it to your app. Different settings should be configured in your config file, so that it is easy to change settings.

Logging is then as easy as:

from loguru import logger

logger.info("I am logging from loguru!")

Multi-node-training on slurm with PyTorch

What's this?

• A simple note for how to start multi-node-training on slurm scheduler with PyTorch.
• Useful especially when scheduler is too busy that you cannot get multiple GPUs allocated, or you need more than 4 GPUs for a single job.
• Requirement: Have to use PyTorch DistributedDataParallel(DDP) for this purpose.
• Warning: might need to re-factor your own code.
• Warning: might be secretly condemned by your colleagues because using too many GPUs.
