Linear probe checkpoints for https://footprints.baulab.info

To load a Llama-2-7b checkpoint at layer 0 and target index -3:

```
import torch 
import torch.nn as nn
from huggingface_hub import hf_hub_download

class LinearModel(nn.Module):
    def __init__(self, input_size, output_size, bias=False):
        super(LinearModel, self).__init__()
        self.fc = nn.Linear(input_size, output_size, bias=bias)
    def forward(self, x):
        output = self.fc(x)
        return output

checkpoint_path = hf_hub_download(
    repo_id="sfeucht/footprints", 
    filename="llama-2-7b/layer0_tgtidx-3.ckpt"
)
probe = LinearModel(4096, 32000)
probe.load_state_dict(torch.load(checkpoint_path, map_location=torch.device('cpu')))
```
