## Troubleshoot

#### Install fails while building Tokenizer dependency
- **Details**: `pip install khoj-assistant` fails while building the `tokenizers` dependency. Complains about Rust.
- **Fix**: Install Rust to build the tokenizers package. For example on Mac run:
    ```shell
    brew install rustup
    rustup-init
    source ~/.cargo/env
    ```
- **Refer**: [Issue with Fix](https://github.com/khoj-ai/khoj/issues/82#issuecomment-1241890946) for more details

#### Search starts giving wonky results
- **Fix**: Open [/api/update?force=true](http://localhost:42110/api/update?force=true) in browser to regenerate index from scratch
- **Note**: *This is a fix for when you percieve the search results have degraded. Not if you think they've always given wonky results*

#### Khoj in Docker 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)

#### Khoj errors out complaining about Tensors mismatch or null
- **Mitigation**: Disable `image` search using the desktop GUI
