7 years ago Hi @lazerwalker, can you use the run_torch_script function to require module successfully? I followed your instructions and added the code as the gist, but I came with the error message like this:
Error in Torch Script: ...D0/Torch7iOSExample.app/framework/lua/optim/init.lua:2: module 'torch' not found:

Almost every added lua script would throw an error message expect framework/lua/torch/init.lua
Can you give me some advice to solve the problem? Thank you!
Hi!
I'm trying to add some third-party libraries that have no C code or cmake compilation step, only Lua code (in my case:
nngraph,optim, and their subdependencies, so I can sample a pre-trained char-rnn dataset).Given that they don't have C code and thus don't generate static libraries, the only thing I've figured out to do with them is dump them in my
/framework/luafolder, and load them as appropriate inTorch.m, as well as evaluate their init.lua files at runtime (see this gist, modified from this example repo).A minor problem with this is that it requires I manually go into each
init.luafile (and a few others) and manually wraprequirecalls inif foo == nilchecks (as recommended in this blog post associated with the example repo above). Not a deal-breaker, but still feels like a code smell I'm taking the wrong approach.More crucially, one library that requires
xluacan't find it, despite the already-includedimagelibrary being able to reference it just fine. Going down the rabbithole of manually including and initializingxluaat runtime (same deal, adding it to/framework/luawithin the iOS project, and loading it withinTorch.mand myTorchInterface.m), and then doing that recursively for each of its dependencies, eventually leads me to needing to include thepathslibrary, which gives me compilation errors when I try to include it as part of thegenerate_ios_frameworkscript.Not being familiar with CMake or anything surrounding Lua (its require/package system, embedding it within iOS, etc), I'm very clearly in over my head. My instinct is that trying to get
pathsto build is too far deep in the yak shave, and there's an overall cleaner approach I should be taking, but darned if I know what it is.It seems like this repo is relatively dormant, but figured I'd put a call out in case any of the maintainers or anyone else stumbling onto this has any thoughts or ideas.
Thanks!
