Don't train deep learning models blindfolded! Be impatient and look at each epoch of your training!

🎉 New release 0.5.0 (20 Mar 2020). See CHANGELOG and updated EXAMPLES IN COLAB. There are some API changes, to make it better, cleaner, and more modular. 🎉

A live training loss plot in Jupyter Notebook for Keras, PyTorch and other frameworks. An open-source Python package by Piotr Migdał, Bartłomiej Olechno and others. Open for collaboration! (Some tasks are as simple as writing code docstrings, so - no excuses! :))

This project supported by Jacek Migdał, Marek Cichy. Join the sponsors - show your ❤️ and support, and appear on the list! It will give me time and energy to work on this project.

from livelossplot import PlotLossesKeras

model.fit(X_train, Y_train,
          epochs=10,
          validation_data=(X_test, Y_test),
          callbacks=[PlotLossesKeras()],
          verbose=0)

So remember, log your loss!

  • (The most FA)Q: Why not TensorBoard?
  • A: Jupyter Notebook compatibility (for exploration and teaching). The simplicity of use.

Installation

To install this version from PyPI, type:

pip install livelossplot

To get the newest one from this repo (note that we are in the alpha stage, so there may be frequent updates), type:

pip install git+git://github.com/stared/livelossplot.git

Examples

Look at notebook files with full working examples:

You run examples in Colab.

Overview

Text logs are easy, but it's easy to miss the most crucial information: is it learning, doing nothing or overfitting? Visual feedback allows us to keep track of the training process. Now there is one for Jupyter.

If you want to get serious - use TensorBoard, . But what if you just want to train a small model in Jupyter Notebook? Here is a way to do so, using livelossplot as a plug&play component

from livelossplot import ...

PlotLosses for a generic API.

plotlosses = PlotLosses()
plotlosses.update({'acc': 0.7, 'val_acc': 0.4, 'loss': 0.9, 'val_loss': 1.1})
plot.send()  # draw, update logs, etc

There are callbacks for common libraries and frameworks: PlotLossesKeras, PlotLossesKerasTF, PlotLossesPoutyne, PlotLossesIgnite.

Feel invited to write, and contribute, your adapter. If you want to use a bare logger, there is MainLogger.

from livelossplot.outputs import ...

Plots: MatplotlibPlot, BokehPlot.

Loggers: ExtremaPrinter (to standard output), TensorboardLogger, TensorboardTFLogger, NeptuneLogger.

To use them, initialize PlotLosses with some outputs:

plotlosses = PlotLosses(outputs=[MatplotlibPlot(), TensorboardLogger()])

There are custom matplotlib plots in livelossplot.outputs.matplotlib_subplots you can pass in MatplotlibPlot arguments.

Trivia

It started as this gist. Since it went popular, I decided to rewrite it as a package.

Oh, and I am in general interested in data vis, see Simple diagrams of convoluted neural networks (and overview of deep learning architecture diagrams):

A good diagram is worth a thousand equations — let’s create more of these!

...or my other data vis projects.

Todo

If you want more functionality - open an Issue or even better - prepare a Pull Request.
