livelossplot

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

(RECENT CHANGES, EXAMPLES IN COLAB, API LOOKUP, CODE)

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! :))

from livelossplot import PlotLossesKeras

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

(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:

keras.ipynb - a Keras callback
minimal.ipynb - a bare API, to use anywhere
bokeh.ipynb - a bare API, plots with Bokeh (open it in Colab to see the plots)
pytorch.ipynb - a bare API, as applied to PyTorch
2d_prediction_maps.ipynb - example of custom plots - 2d prediction maps (0.4.1+)
poutyne.ipynb - a Poutyne callback (Poutyne is a Keras-like framework for PyTorch)
torchbearer.ipynb - an example using the built in functionality from torchbearer (torchbearer is a model fitting library for PyTorch)
neptune.py and neptune.ipynb - a Neptune.AI
matplotlib.ipynb - a Matplotlib output example
various_options.ipynb - an extended API for metrics grouping and custom outputs

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.

If you like to plot with Bokeh instead of matplotlib, use

plotlosses = PlotLosses(outputs=[BokehPlot()])

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
