# Khoj
|
|
|
|
*Allow natural language search on user content like notes, images,
|
|
transactions using transformer ML models*
|
|
|
|
User can interface with Khoj via [Web](./src/interface/web/index.html),
|
|
[Emacs](./src/interface/emacs/khoj.el) or the API. All search is done
|
|
locally[\*](https://github.com/debanjum/khoj#miscellaneous)
|
|
|
|
## Demo
|
|
|
|
<https://user-images.githubusercontent.com/6413477/168417719-8a8bc4e5-8404-42b2-89a7-4493e3d2582c.mp4>
|
|
|
|
## Setup
|
|
|
|
### 1. Clone
|
|
|
|
``` shell
|
|
git clone https://github.com/debanjum/khoj && cd khoj
|
|
```
|
|
|
|
### 2. Configure
|
|
|
|
- \[Required\] Update [docker-compose.yml](./docker-compose.yml) to
|
|
mount your images, (org-mode or markdown) notes and beancount
|
|
directories
|
|
- \[Optional\] Edit application configuration in
|
|
[khoj_sample.yml](./config/khoj_sample.yml)
|
|
|
|
### 3. Run
|
|
|
|
``` shell
|
|
docker-compose up -d
|
|
```
|
|
|
|
*Note: The first run will take time. Let it run, it\'s mostly not hung,
|
|
just generating embeddings*
|
|
|
|
## Use
|
|
|
|
- **Khoj via API**
|
|
- See [Khoj API Docs](http://localhost:8000/docs)
|
|
- [Query](http://localhost:8000/search?q=%22what%20is%20the%20meaning%20of%20life%22)
|
|
- [Regenerate
|
|
Embeddings](http://localhost:8000/regenerate?t=ledger)
|
|
- [Configure Application](https://localhost:8000/ui)
|
|
- **Khoj via Emacs**
|
|
- [Install](https://github.com/debanjum/khoj/tree/master/src/interface/emacs#installation)
|
|
[khoj.el](./src/interface/emacs/khoj.el)
|
|
- Run `M-x khoj <user-query>`
|
|
|
|
## Run Unit tests
|
|
|
|
``` shell
|
|
pytest
|
|
```
|
|
|
|
## Upgrade
|
|
|
|
``` shell
|
|
docker-compose build --pull
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
- Symptom: Errors out with \"Killed\" in error message
|
|
- Fix: Increase RAM available to Docker Containers in Docker
|
|
Settings
|
|
- Refer: [StackOverflow
|
|
Solution](https://stackoverflow.com/a/50770267), [Configure
|
|
Resources on Docker for
|
|
Mac](https://docs.docker.com/desktop/mac/#resources)
|
|
- Symptom: Errors out complaining about Tensors mismatch, null etc
|
|
- Mitigation: Delete content-type \> image section from
|
|
docker~sampleconfig~.yml
|
|
|
|
## Miscellaneous
|
|
|
|
- The experimental [chat](localhost:8000/chat) API endpoint uses the
|
|
[OpenAI API](https://openai.com/api/)
|
|
- It is disabled by default
|
|
- To use it add your `openai-api-key` to config.yml
|

## Development Setup
|
|
|
|
### Setup on Local Machine
|
|
|
|
1. 1\. Install Dependencies
|
|
|
|
1. Install Python3 \[Required\]
|
|
|
|
2. [Install
|
|
Conda](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html)
|
|
\[Required\]
|
|
|
|
3. Install Exiftool \[Optional\]
|
|
|
|
``` shell
|
|
sudo apt-get -y install libimage-exiftool-perl
|
|
```
|
|
|
|
2. 2\. Install Khoj
|
|
|
|
``` shell
|
|
git clone https://github.com/debanjum/khoj && cd khoj
|
|
conda env create -f config/environment.yml
|
|
conda activate khoj
|
|
```
|
|
|
|
3. 3\. Configure
|
|
|
|
- Configure files/directories to search in `content-type` section
|
|
of `khoj_sample.yml`
|
|
- To run application on test data, update file paths containing
|
|
`/data/` to `tests/data/` in `khoj_sample.yml`
|
|
- Example replace `/data/org/*.org` with
|
|
`tests/data/org/*.org`
|
|
|
|
4. 4\. Run
|
|
|
|
Load ML model, generate embeddings and expose API to query notes,
|
|
images, transactions etc specified in config YAML
|
|
|
|
``` shell
|
|
python3 -m src.main -c=config/khoj_sample.yml -vv
|
|
```
|
|
|
|
### Upgrade On Local Machine
|
|
|
|
``` shell
|
|
cd khoj
|
|
git pull origin master
|
|
conda deactivate khoj
|
|
conda env update -f config/environment.yml
|
|
conda activate khoj
|
|
```
