Nitro

Nitro is a high-efficiency C++ inference engine for edge computing. It is lightweight and embeddable, and can be used on its own within your own projects.

Troubleshooting

As Jan is in development mode, you might get stuck on a broken build.

To reset your installation:

Use the following commands to remove any dangling backend processes:
```
ps aux | grep nitro
```
Look for processes like "nitro" and "nitro_arm_64," and kill them one by one with:
```
kill -9 <PID>
```
Remove Jan from your Applications folder and Cache folder
```
make clean
```
This will remove all build artifacts and cached files:
- Delete Jan extension from your ~/jan/extensions folder
- Delete all node_modules in current folder
- Clear Application cache in ~/Library/Caches/jan
