* init trtllm attn no cache

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* fix: fix the seq_len issue and attn metadata prepare for qwen reward model test

fix: fix minor bugs after rebase
Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: remove unnecessary debug logs and clean up commented code

refactor: update max_seq_len documentation and remove max_seq_len for decoder model contructor in PyTorchModelEngine
Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: update calculate_ref_result function to accept tensor inputs and mask type, enhance test_attention_no_cache to support FULL and CAUSAL masks

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: remove unused BERT attention metadata conversion method and add type assertion for no cache attention in PyTorchModelEngine

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: remove use_kv_cache parameter from attention function and related classes, update documentation for KV cache handling

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: implement setAttentionMaskType method for better mask type handling and remove unused conversion function

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: streamline KV cache handling by replacing direct member access with useKVCache method and simplify token per block assignment

remove Debug code.

* refactor: Resolve comments for Python code

Simplify no cache attention metadata preparation and streamline related attributes in TrtllmAttentionMetadata

Removed the private method for converting to no cache attention metadata and integrated its logic into the prepare method. Updated the test for BERT sequence classification to reflect these changes and ensure proper handling of attention metadata.

* docs: Add is_dummy_attention field to attention metadata for simulation operations

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* refactor: add KVCacheParams to attention backend interface and import relevant metadata classes

Updated the attention backend interface to include KVCacheParams and imported TrtllmAttentionMetadata and VanillaAttentionMetadata in model_engine.py for enhanced functionality.

* fix: fix rebase format issue

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* fix: extend attention mask type handling in MHARunnerFixedParams

Added support for additional attention mask types (BIDIRECTIONAL, BIDIRECTIONALGLM, BLOCKSPARSE) in the MHARunnerFixedParams structure to fix the mapping issue between ContextAttentionMaskType and AttentionMaskType

Signed-off-by: Qixiang Lin <qixiangl@nvidia.com>

* fix: enhance attention mask type handling in TllmGenFmhaRunnerParams

Updated the setAttentionMaskType method to include a switch-case structure for better handling of attention mask types, ensuring proper mapping and error handling for invalid types.

Docs

This directory contains the stuff for building static html documentations based on sphinx.

Build the docs

Firstly, install the sphinx:

apt-get install python3-sphinx doxygen python3-pip graphviz

Secondly, install the packages:

python3 -m pip install -r ./requirements.txt

And then, make the docs:

doxygen Doxygen # build C++ docs

make html

And the finally the generated html pages will locate in the build/html directory.

Preview the docs locally

The basic way to preview the docs is using the http.serve:

cd build/html

python3 -m http.server 8081

And you can visit the page with your web browser with url http://localhost:8081.
