Question

Is there a way to execute grid.py without running gnuplot? I would rather not display the plots or warnings associate with the program.

Answer 1

Here’s the source of grid.py (in my github mirror of the libsvm code).

It’s not very customizable; there’s some options done by silly manual parsing instead of optparse/etc, and the path to gnuplot is even hardcoded; no options not to draw. But it shouldn’t be hard to modify the file and just rip out all the gnuplot-related code.

In fact, I think all you have to do is comment out the last line of process_options

gnuplot = Popen(gnuplot_exe,stdin = PIPE).stdin

and the calls to redraw() near the end of main().
