cmdline problem with using booleans

[Afroze Ibrahim]

Im trying to use comman line arguments, which work fine except when expecting a boolean input.

For example if torch code is:

adaptiveLR = true

cmd=torch.CmdLine();

cmd:option('-adaptive',adaptiveLR,'diminishing learning rate');

And I give the command line argument:

-adaptive false

I get an error:

invalid argument: false

Usage: [options]

  -adaptive diminishing learning rate [true]

I think it is happening because the command line is interpreting the <false> as a string and not boolean. Any way to get around this?

Thanks!

Maybe use 0/1?

It turns out only "null" and "false" values are considered as false booleans while all rest (including 0 and 1) are considered true. So I can't use them...

I can obviously check specifically for integer 0 or 1 and interpret them myself as true and false, but I'm just wondering if there is a proper way to deal with booleans?

When you specify a boolean value, you should use a default of false.

That way when you want to turn the switch on, you just specify:

th myfile.lua --adaptive

Which turns adaptive=true.
