Simplified Gemma.cpp Example
This is a minimal/template project for using gemma.cpp as a library. Instead
of an interactive interface, it sets up the model state and generates text for a
single hard coded prompt.
Build steps are similar to the main gemma executable. For now only
cmake/make is available for builds (PRs welcome for other build options).
First use cmake to configure the project, starting from the simplified_gemma
example directory (gemma.cpp/examples/simplified_gemma):
cmake -B build
This sets up a build configuration in gemma.cpp/examples/simplified_gemma/build.
Note that this fetches libgemma from a git commit hash on github.
Alternatively if you want to build using the local version of gemma.cpp use:
cmake -B build -DBUILD_MODE=local
Make sure you delete the contents of the build directory before changing configurations.
Then use make to build the project:
cd build
make simplified_gemma
As with the top-level gemma.cpp project you can use the make commands -j
flag to use parallel threads for faster builds.
From inside the gemma.cpp/examples/simplified_gemma/build directory, there should
be a simplified_gemma executable. You can run it with the same 3 model arguments as
gemma.cpp specifying the tokenizer, compressed weights file, and model type, for
example:
./simplified_gemma --tokenizer tokenizer.spm --weights 2b-it-sfp.sbs --model 2b-it
Should print a greeting to the terminal:
"Hello, world! It's a pleasure to greet you all. May your day be filled with joy, peace, and all the things that make your heart soar.
For a demonstration of constrained decoding, add the --reject flag followed by
a list of token IDs (note that it must be the last flag, since it consumes every
subsequent argument). For example, to reject variations of the word "greeting",
run:
./simplified_gemma [...] --reject 32338 42360 78107 106837 132832 143859 154230 190205
