logboard 0.2.0

Monitor and Compare Logs on Browser.

logboard

Monitor and Compare Logs on Browser/Terminal.

Description

Inspired by tensorboard, grip and notable, all of which serve light-weight GUI by

• only using static files (e.g., markdown files without DB);
• single command (e.g., tensorboard --logdir logs/ and grip README.md).

Why not tensorboard?

I also use tensorboard in addition to this tool. But currently tensorboard doesn't support comparing different configurations for each log (e.g., git-hash of the code, learning rate, training strategy). logboard is a kind of extra plugin to tensorboard (but you need to run in different terminal, unfortunately). I expect this kind of feature will be included in tensorboard in the future.

Usage

Browser (logboard)

$ cd examples

$ cat .logboard
[logboard]
-summary=out,timestamp,loglevel,gpu,seed,lr .*,.*main/loss.*(max)

$ cat logs/20190310_093252.724597/args
{
    "loglevel": "info",
    "gpu": 0,
    "seed": 0,
    "class_ids": [
        1
    ],
    "lr": 0.001,
    "timestamp": "2019-03-10T09:32:52.724597",
    "out": "/home/wkentaro/logboard/examples/logs/20190310_093252.724597",
    "hostname": "computer1",
    "githash": "b48ce48"
}

$ logboard --logdir logs/  # like tensorboard --logdir logs/

Terminal (logtable)

$ cd examples

$ logtable --hide updated_at epoch hostname class_ids 'main/loss_quaternion (min)' 'main/loss_translation (min)' 'validation/main/loss_quaternion (min)' 'validation/main/loss_translation (min)'
