PiperOrigin-RevId: 641311100
 2024-06-07 11:38:42 -07:00
Jan Wassenberg f9b390b134 Support all weight types in a single binary. 
This changes the command line flags, but the default value retains the previous behavior.

Also add a CreateGemma helper to enable extra args without interface changes.

Daniel Keysers 06f814fc8b Small code cleanup suggestions while reading the code. 
PiperOrigin-RevId: 641220788
 2024-06-07 05:33:17 -07:00
Zoltan Szabadka 465998d25a Add support for custom sampling function to runtime config. 
With this addition the ComputeCrossEntropy function can be moved
to its own library, because now we can compute it using only the
public API functions from gemma.h

 2024-06-07 02:25:18 -07:00
Jan Wassenberg e3f4374e81 Fix fix for weight type define, refs #198 
GEMMA_WEIGHT_T is indeed the correct flag for the C++ compiler,
but the readme references CMake, and there the correct flag name is WEIGHT_TYPE.

Centralize switch(Model) to avoid duplication
Move CompressWeightsT to compress_weights.cc
Move LoadWeights to weights.cc

Zoltan Szabadka 36e4d8bbfe Add first version of backpropagation support. 
This is still in progress / experimental, currently it is only
implemented for normal gemma MQA attention layers, and no
parallelism is added yet for backward pass.

Since we need to remember all activations from all layers, the
forward pass was also reimplemented with a new activation data
structure.
