This notebook uses Lucid to reproduce some of the results in Feature Visualization.
This notebook doesn't introduce the abstractions behind lucid; you may wish to also read the .
Note: The easiest way to use this tutorial is as a colab notebook, which allows you to dive in with no setup. We recommend you enable a free GPU by going:
Runtime → Change runtime type → Hardware Accelerator: GPU
