@apaniukov is there C++ API for tokenization and detokenization? |
Yes, there is. Right now is on openvin_contrib branch. Here is an instruction for building and installation. It does not support llama tokenizers from Then you can convert tokenizer to OV models: from transformers import AutoTokenizer
from openvino import save_model
from ov_tokenizer import init_extension, convert_tokenizer
init_extension("path/to/libuser_ov_extensions.so")
hf_tokenizer = AutoTokenizer.from_pretrained("microsoft/Llama2-7b-WhoIsHarryPotter")
ov_tokenizer, ov_detokenizer = convert_tokenizer(hf_tokenizer, with_decoder=True)
save_model(ov_tokenizer, "tokenizer.xml")
save_model(ov_detokenizer, "detokenizer.xml")From here you can work with them like with any other OV model. You can also add similar postprocessing to the llama model to get Models cannot work with strings at this point, so you need to convert the input to uint8 tensor with a predefined format, see pack_strings. To get strings from the detokenizer uint8 output, see unpack_strings. |

@yury-gorbachev, I was told that you requested to add beam search. Should it be a separate application or should I provide beam search implementation only given that beam size of 1 is greedy sampling?

I'm going to merge greedy sampling for now to unblock others

we have Tensor::copy_to, which can also allocate output tensor

let's move this code to contrib
Verify beam_idx added, upgrade OpenVINO
Adding lib to bazel
…tion-pavel Integrate JinjaCpp
Added embedding pipeline and embedding handle, encapsulated handle code
