TRAINS

Auto-Magical Experiment Manager & Version Control for AI

"Because it’s a jungle out there"

TRAINS is our solution to a problem we share with countless other researchers and developers in the machine learning/deep learning universe: Training production-grade deep learning models is a glorious but messy process. TRAINS tracks and controls the process by associating code version control, research projects, performance metrics, and model provenance.

We designed TRAINS specifically to require effortless integration so that teams can preserve their existing methods and practices. Use it on a daily basis to boost collaboration and visibility, or use it to automatically collect your experimentation logs, outputs, and data to one centralized server.

(Experience TRAINS live at https://demoapp.trainsai.io)

TRAINS Automatically Logs Everything

With only two lines of code, this is what you are getting:

Git repository, branch, commit id, entry point and local git diff
Python environment (including specific packages & versions)
stdout and stderr
Resource Monitoring (CPU/GPU utilization, temperature, IO, network, etc.)
Hyper-parameters
- ArgParser for command line parameters with currently used values
- Explicit parameters dictionary
- Tensorflow Defines (absl-py)
Initial model weights file
Model snapshots
Tensorboard/TensorboardX scalars, metrics, histograms, images (with audio coming soon)
Matplotlib & Seaborn
Supported frameworks: Tensorflow, PyTorch, Keras, XGBoost and Scikit-Learn (MxNet is coming soon)
Seamless integration (including version control) with Jupyter Notebook and PyCharm remote debugging

Additionally, log data explicitly using TRAINS Explicit Logging.

Using TRAINS

TRAINS is a two part solution:

TRAINS python package auto-magically connects with your code

TRAINS requires only two lines of code for full integration.

To connect your code with TRAINS:
- Install TRAINS
```
  pip install trains
```
- Add the following lines to your code
```
  from trains import Task
  task = Task.init(project_name="my project", task_name="my task")
```
  - If project_name is not provided, the repository name will be used instead
  - If task_name (experiment) is not provided, the current filename will be used instead
- Run your code. When TRAINS connects to the server, a link is printed. For example
```
  TRAINS Results page:
  https://demoapp.trainsai.io/projects/76e5e2d45e914f52880621fe64601e85/experiments/241f06ae0f5c4b27b8ce8b64890ce152/output/log
```
- Open the link and view your experiment parameters, model and tensorboard metrics
See examples here
TRAINS-server for logging, querying, control and UI (Web-App)

We have a demo server up and running at https://demoapp.trainsai.io. You can try out TRAINS and test your code with it. Note that it resets every 24 hours and all of the data is deleted.

When you are ready to use your own TRAINS server, go ahead and install TRAINS-server.

Configuring Your Own TRAINS server

Install and run TRAINS-server (see Installing the TRAINS Server)
Run the initial configuration wizard for your TRAINS installation and follow the instructions to setup TRAINS package (http://trains-server-ip:port and user credentials)
```
 trains-init
```

After installing and configuring, you can access your configuration file at ~/trains.conf

Sample configuration file available here.

Who We Are

TRAINS is supported by the same team behind allegro.ai, where we build deep learning pipelines and infrastructure for enterprise companies.

We built TRAINS to track and control the glorious but messy process of training production-grade deep learning models. We are committed to vigorously supporting and expanding the capabilities of TRAINS.

Why Are We Releasing TRAINS?

We believe TRAINS is ground-breaking. We wish to establish new standards of experiment management in deep-learning and ML. Only the greater community can help us do that.

We promise to always be backwardly compatible. If you start working with TRAINS today, even though this project is currently in the beta stage, your logs and data will always upgrade with you.
