[Joinhack]

Hello, I compile this project to wasm, but when I run it crash.

@ggerganov any chance you could give us some pointers? :) Much obliged.

Hard to tell - could be some problem with the WASM code. It's not very well tested.

Try this patch and see what happens:

diff --git a/src/ggml.c b/src/ggml.c
index d2a9dab..8a11f7c 100644

yes, it work, but other error occur.

@Joinhack , if you're using Emscripten then try adding these flags and values during compilation:
-s INITIAL_MEMORY=1000MB -s MAXIMUM_MEMORY=4GB -s STACK_SIZE=11524288 -s ALLOW_MEMORY_GROWTH

This should get around the memory limitations. Example Script: https://github.com/rahuldshetty/ggml.js/blob/master/build-ggml.sh
