"""Create HTML file with dynamic visualizing of a Theano function graph.
In the HTML file, the whole graph or single nodes can be moved by drag and
drop. Zooming is possible via the mouse wheel. Detailed information about
nodes and edges are displayed via mouse-over events. Node labels can be
edited by selecting Edit from the context menu.
Input nodes are colored in green, output nodes in blue. Apply nodes are
ellipses, and colored depending on the type of operation they perform. Red
ellipses are transfers from/to the GPU (ops with names GpuFromHost,
HostFromGpu).
Edges are black by default. If a node returns a view of an
input, the input edge will be blue. If it returns a destroyed input, the
edge will be red.
Parameters
----------
fct : theano.compile.function_module.Function
A compiled Theano function, variable, apply or a list of variables.
outfile : str
Path to output HTML file.
copy_deps : bool, optional
Copy javascript and CSS dependencies to output directory.
