COHERE experiments

Getting COHERE Data

Please download the COHERE 10M dataset to cohere_large_10m as follows:

bash

... ...           
neighbors.parquet    
shuffle_train-00-of-10.parquet     
shuffle_train-01-of-10.parquet          
shuffle_train-02-of-10.parquet  
shuffle_train-03-of-10.parquet 
shuffle_train-04-of-10.parquet  
shuffle_train-05-of-10.parquet 
shuffle_train-06-of-10.parquet
shuffle_train-07-of-10.parquet
shuffle_train-08-of-10.parquet
shuffle_train-09-of-10.parquet
scalar_labels.parquet     
test.parquet

For convenience, we prepared a docker image with cohere bench datasets: registry.cn-hongkong.cr.aliyuncs.com/zvec/cohere-bench-data.

You can run a container as follows:

bash

docker run -it --net=host -d -e DEBUG_MODE=true  --user root --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -v /home/zvec/:/home/zvec/  -w /home/zvec --name=cohere_bench zvec-registry.cn-hongkong.cr.aliyuncs.com/zvec/cohere-bench-data:0.0.1 bash

docker exec -it cohere_bench bash

The datasets locate at /tmp/cohere/

Preparing Environment

Clone code and init:

bash

$ git clone [email protected]:alibaba/zvec.git
$ cd zvec
$ git submodule update --init

Build source code:

$ cd /home/zvec/workspace/zvec
$ mkdir build
$ cd build  
$ cmake -DENABLE_SKYLAKE=ON -DCMAKE_BUILD_TYPE=Release ..

Converting Dataset

Export vector data using python script:

bash

$ mkdir 10m.output
$ python3 convert_cohere_parquet.py

Convert vector data to binary formatted file.

bash

/home/zvec/workspace/zvec/bin/txt2vecs -input=cohere_train_vector_10m.txt --output=cohere_train_vector_10m.zvec.vecs --dimension=768

We've also prepared preprocessed binary formatted files, which can be found in the container below:

bash
