:wrench: Installation
Step1: Install MindSpore
Due to the fact that the installation of MindSpore framework depends on different hardware platforms, we do not directly install it automatically. Please follow the official installation link for installation.
Official Installation Link: https://www.mindspore.cn/install
Step2: Install mindnlp
You can install the official version of MindNLP which is uploaded to pypi.
pip install mindnlp
Step3: Install FlashRAG-MindSpore
Then, simply clone it from Github and install (requires Python 3.9+):
git clone https://github.com/RUC-NLPIR/FlashRAG-MindSpore.git
cd FlashRAG-MindSpore
pip install -e .
Due to the incompatibility when installing faiss
using pip
, it is necessary to use the following conda command for installation.
# CPU-only version
conda install -c pytorch faiss-cpu=1.8.0
# GPU(+CPU) version
conda install -c pytorch -c nvidia faiss-gpu=1.8.0
Note: It is impossible to install the latest version of faiss
on certain systems.
From the official Faiss repository (source):
- The CPU-only faiss-cpu conda package is currently available on Linux (x86_64 and arm64), OSX (arm64 only), and Windows (x86_64)
- faiss-gpu, containing both CPU and GPU indices, is available on Linux (x86_64 only) for CUDA 11.4 and 12.1
:rocket: Quick Start
Toy Example
For beginners, we provide a <u>an introduction to flashrag</u> (<u>中文版</u> <u>한국어</u>) to help you familiarize yourself with our toolkit. Alternatively, you can directly refer to the code below.
Demo
We provide a toy demo to implement a simple RAG process. You can freely change the corpus and model you want to use. The English demo uses general knowledge as the corpus, e5-base-v2
as the retriever, and Llama3-8B-instruct
as generator. The Chinese demo uses data crawled from the official website of Remin University of China as the corpus, bge-large-zh-v1.5
as the retriever, and qwen1.5-14B as the generator. Please fill in the corresponding path in the file.
To run the demo:
cd examples/quick_start
# copy the config file here, otherwise, streamlit will complain that file s
cp ../methods/my_config.yaml .
# run english demo
streamlit run demo_en.py
# run chinese demo
streamlit run demo_zh.py
Pipeline
We also provide an example to use our framework for pipeline execution.
Run the following code to implement a naive RAG pipeline using provided toy datasets.
The default retriever is e5-base-v2
and default generator is Llama3-8B-instruct
. You need to fill in the corresponding model path in the following command. If you wish to use other models, please refer to the detailed instructions below.
cd examples/quick_start
python simple_pipeline.py \
--model_path <Llama-3-8B-instruct-PATH> \
--retriever_path <E5-PATH>
After the code is completed, you can view the intermediate results of the run and the final evaluation score in the output folder under the corresponding path.
Using the ready-made pipeline
You can use the pipeline class we have already built (as shown in <u>pipelines</u>) to implement the RAG process inside. In this case, you just need to configure the config and load the corresponding pipeline.
Firstly, load the entire process's config, which records various hyperparameters required in the RAG process. You can input yaml files as parameters or directly as variables. The priority of variables as input is higher than that of files.
from flashrag.config import Config
config_dict = {'data_dir': 'dataset/'}
my_config = Config(config_file_path = 'my_config.yaml',
config_dict = config_dict)
We provide comprehensive guidance on how to set configurations, you can see our <u>configuration guidance</u>. You can also refer to the <u>basic yaml file</u> we provide to set your own parameters.
Next, load the corresponding dataset and initialize the pipeline. The components in the pipeline will be automatically loaded.
from flashrag.utils import get_dataset
from flashrag.pipeline import SequentialPipeline
from flashrag.prompt import PromptTemplate
from flashrag.config import Config
config_dict = {'data_dir': 'dataset/'}
my_config = Config(config_file_path = 'my_config.yaml',
config_dict = config_dict)
all_split = get_dataset(my_config)
test_data = all_split['test']
pipeline = SequentialPipeline(my_config)
You can specify your own input prompt using PromptTemplete
:
prompt_templete = PromptTemplate(
config,
system_prompt = "Answer the question based on the given document. Only give me the answer and do not output any other words.\nThe following are given documents.\n\n{reference}",
user_prompt = "Question: {question}\nAnswer:"
)
pipeline = SequentialPipeline(my_config, prompt_template=prompt_templete)
Finally, execute pipeline.run
to obtain the final result.
output_dataset = pipeline.run(test_data, do_eval=True)
The output_dataset
contains the intermediate results and metric scores for each item in the input dataset.
Meanwhile, the dataset with intermediate results and the overall evaluation score will also be saved as a file (if save_intermediate_data
and save_metric_score
are specified).
Build your own pipeline
Sometimes you may need to implement more complex RAG process, and you can build your own pipeline to implement it.
You just need to inherit BasicPipeline
, initialize the components you need, and complete the run
function.
from flashrag.pipeline import BasicPipeline
from flashrag.utils import get_retriever, get_generator
class ToyPipeline(BasicPipeline):
def __init__(self, config, prompt_templete=None):
# Load your own components
pass
def run(self, dataset, do_eval=True):
# Complete your own process logic
# get attribute in dataset using `.`
input_query = dataset.question
...
# use `update_output` to save intermeidate data
dataset.update_output("pred",pred_answer_list)
dataset = self.evaluate(dataset, do_eval=do_eval)
return dataset
Please first understand the input and output forms of the components you need to use from our <u>documentation</u>.
Just use components
If you already have your own code and only want to use our components to embed the original code, you can refer to the <u>basic introduction of the components</u> to obtain the input and output formats of each component.
:gear: Components
In FlashRAG, we have built a series of common RAG components, including retrievers, generators, refiners, and more. Based on these components, we have assembled several pipelines to implement the RAG workflow, while also providing the flexibility to combine these components in custom arrangements to create your own pipeline.

Referring to a <u>survey on retrieval-augmented generation</u>, we categorized RAG methods into four types based on their inference paths.
- Sequential: Sequential execuation of RAG process, like Query-(pre-retrieval)-retriever-(post-retrieval)-generator
- Conditional: Implements different paths for different types of input queries
- Branching : Executes multiple paths in parallel, merging the responses from each path
- Loop: Iteratively performs retrieval and generation
In each category, we have implemented corresponding common pipelines. Some pipelines have corresponding work papers.

Based on MindSpore Framework, we currently have implemented 9 works with a consistent setting of:
- Generator: LLAMA3-8B-instruct with input length of 2048
- Retriever: e5-base-v2 as embedding model, retrieve 5 docs per query
- Prompt: A consistent default prompt, template can be found in the <u>method details</u>.
For open-source methods, we implemented their processes using our framework. For methods where the author did not provide source code, we will try our best to follow the methods in the original paper for implementation.
For necessary settings and hyperparameters specific to some methods, we have documented them in the specific settings column. For more details, please consult our <u>reproduce guidance</u> and <u>method details</u>.
It’s important to note that, to ensure consistency, we have utilized a uniform setting. However, this setting may differ from the original setting of the method, leading to variations in results compared to the original outcomes.

:notebook: Supporting Datasets & Document Corpus
Datasets
We have collected and processed 36 datasets widely used in RAG research, pre-processing them to ensure a consistent format for ease of use. For certain datasets (such as Wiki-asp), we have adapted them to fit the requirements of RAG tasks according to the methods commonly used within the community. All datasets are available at <u>Huggingface datasets</u>.
For each dataset, we save each split as a jsonl
file, and each line is a dict as follows:
{
'id': str,
'question': str,
'golden_answers': List[str],
'metadata': dict
}
Below is the list of datasets along with the corresponding sample sizes:

Document Corpus
Our toolkit supports jsonl format for retrieval document collections, with the following structure:
{"id":"0", "contents": "...."}
{"id":"1", "contents": "..."}
The contents
key is essential for building the index. For documents that include both text and title, we recommend setting the value of contents
to {title}\n{text}
. The corpus file can also contain other keys to record additional characteristics of the documents.
In the academic research, Wikipedia and MS MARCO are the most commonly used retrieval document collections. For Wikipedia, we provide a <u>comprehensive script</u> to process any Wikipedia dump into a clean corpus. Additionally, various processed versions of the Wikipedia corpus are available in many works, and we have listed some reference links.
For MS MARCO, it is already processed upon release and can be directly downloaded from its <u>hosting link</u> on Hugging Face.
Index
To facilitate easier replication of the experiments, we now provide a preprocessed index available in the ModelScope dataset page: FlashRAG_Dataset/retrieval_corpus/wiki18_100w_e5_index.zip.
The index was created using the e5-base-v2 retriever on our uploaded wiki18_100w dataset, which is consistent with the index used in our experiments.
