Aim has built-in converters to easily migrate logs from other tools. These migrations cover the most common usage scenarios. In case of custom and complex scenarios you can use Aim SDK to implement your own conversion script.

• TensorBoard logs converter
• MLFlow logs converter
• Weights & Biases logs converter

Aim easily integrates with a wide range of ML frameworks, providing built-in callbacks for most of them.

Aim Python SDK empowers you to query and access any piece of tracked metadata with ease.

from aim import Repo

my_repo = Repo('/path/to/aim/repo')

query = "metric.name == 'loss'" # Example query

# Get collection of metrics
for run_metrics_collection in my_repo.query_metrics(query).iter_runs():
    for metric in run_metrics_collection:
        # Get run params
        params = metric.run[...]
        # Get metric values
        steps, metric_values = metric.values.sparse_numpy()

Aim remote tracking server allows running experiments in a multi-host environment and collect tracked data in a centralized location.

See the docs on how to set up the remote server.

Training run comparison

Order of magnitude faster training run comparison with Aim

• The tracked params are first class citizens at Aim. You can search, group, aggregate via params - deeply explore all the tracked data (metrics, params, images) on the UI.
• With tensorboard the users are forced to record those parameters in the training run name to be able to search and compare. This causes a super-tedius comparison experience and usability issues on the UI when there are many experiments and params. TensorBoard doesn't have features to group, aggregate the metrics

Scalability

• Aim is built to handle 1000s of training runs - both on the backend and on the UI.
• TensorBoard becomes really slow and hard to use when a few hundred training runs are queried / compared.

Beloved TB visualizations to be added on Aim

• Embedding projector.
• Neural network visualization.

MLFlow is an end-to-end ML Lifecycle tool. Aim is focused on training tracking. The main differences of Aim and MLflow are around the UI scalability and run comparison features.

Aim and MLflow are a perfect match - check out the aimlflow - the tool that enables Aim superpowers on Mlflow.

Run comparison

• Aim treats tracked parameters as first-class citizens. Users can query runs, metrics, images and filter using the params.
• MLFlow does have a search by tracked config, but there are no grouping, aggregation, subplotting by hyparparams and other comparison features available.

UI Scalability

• Aim UI can handle several thousands of metrics at the same time smoothly with 1000s of steps. It may get shaky when you explore 1000s of metrics with 10000s of steps each. But we are constantly optimizing!
• MLflow UI becomes slow to use when there are a few hundreds of runs.

Hosted vs self-hosted

• Weights and Biases is a hosted closed-source MLOps platform.
• Aim is self-hosted, free and open-source experiment tracking tool.

Aim UI

• Runs management
  • Runs explorer – query and visualize runs data(images, audio, distributions, ...) in a central dashboard
• Explorers
  • Distributions Explorer

SDK and Storage

• Scalability
  • Smooth UI and SDK experience with over 10.000 runs
• Runs management
  • CLI commands
    • Reporting - runs summary and run details in a CLI compatible format
    • Manipulations – copy, move, delete runs, params and sequences
• Cloud storage support – store runs blob(e.g. images) data on the cloud
• Artifact storage – store files, model checkpoints, and beyond
