A Latex Printing Example using CuTe DSL.
|
|
This example prints latex for a given layout or thread value layout.
|
|
The primary goal for this example is to demonstrate how to dump latex, which can then be
|
|
turned into an image in your favorite latex compiler.
|
|
To run this example:
|
|
.. code-block:: bash
|
|
python examples/python/CuteDSL/cute/print_latex.py
|
|
python examples/python/CuteDSL/cute/print_latex.py --tv_layout
|
|
To compile, pipe the output to a file and use a tool like pdflatex:
|
|
.. code-block:: bash
|
|
python examples/python/CuTeDSL/cute/print_latex.py > latex.tex
|
|
pdflatex latex.tex
|
|
