Vizualization support for Perl interface to MXNet machine learning library
convert symbol for detail information Parameters ---------- symbol: AI::MXNet::Symbol symbol to be visualized shape: hashref hashref of shapes, str->shape (arrayref[int]), given input shapes line_length: int total length of printed lines positions: arrayref[float] relative or absolute positions of log elements in each line Returns ------ nothing
convert symbol to dot object for visualization Parameters ---------- title: str title of the dot graph symbol: AI::MXNet::Symbol symbol to be visualized shape: HashRef[Shape] If supplied, the visualization will include the shape of each tensor on the edges between nodes. node_attrs: HashRef of node's attributes for example: {shape => "oval",fixedsize => "false"} means to plot the network in "oval" hide_weights: Bool if True (default) then inputs with names like `*_weight` or `*_bias` will be hidden Returns ------ dot: Diagraph dot object of symbol
