Lucid is a collection of infrastructure and tools for research in neural
network interpretability.

**We're not currently supporting tensorflow 2!**

If you'd like to use lucid in colab which defaults to tensorflow 2, add this magic to a cell before you import tensorflow:

```%tensorflow_version 1.x```

**Lucid is research code, not production code. We provide no guarantee it will work for your use case. Lucid is maintained by volunteers who are unable to provide significant technical support.**

# Notebooks

Start visualizing neural networks ***with no setup***. The following notebooks
run right from your browser, thanks to [Colaboratory](https://colab.research.google.com/notebooks/welcome.ipynb). It's a Jupyter notebook environment that requires no setup to use and runs entirely in the cloud.

You can run the notebooks on your local machine, too. Clone the repository and find them in the `notebooks` subfolder. You will need to run a local instance of the [Jupyter notebook environment](http://jupyter.org/install.html) to execute them.

<!--If you want to study techniques for visualizing and understanding neural networks, it's important to be able to try your experiments on multiple models. As of lucid v0.3, we provide a consistent API for interacting with 27 different vision models.-->

## Special consideration for TensorFlow dependency

Lucid requires `tensorflow`, but does not explicitly depend on it in `setup.py`. Due to the way [tensorflow is packaged](https://github.com/tensorflow/tensorflow/issues/7166) and some deficiencies in how pip handles dependencies, specifying either the GPU or the non-GPU version of tensorflow will conflict with the version of tensorflow your already may have installed.

If you don't want to add your own dependency on tensorflow, you can specify which tensorflow version you want lucid to install by selecting from `extras_require` like so: `lucid[tf]` or `lucid[tf_gpu]`.

**In actual practice, we recommend you use your already installed version of tensorflow.**
