## Usage
Please check out the [OpenTSLM](https://github.com/OpenTSLM/OpenTSLM) repository for detailed usage examples.
```python
import sys
import os
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "src")))

from model.llm.OpenTSLM import OpenTSLM
from time_series_datasets.TSQADataset import TSQADataset
from time_series_datasets.util import extend_time_series_to_match_patch_size_and_aggregate
from torch.utils.data import DataLoader
from model_config import PATCH_SIZE

REPO_ID = "OpenTSLM/llama-3.2-1b-tsqa-sp"

# Use CPU or CUDA for inference. MPS does NOT work for pretrained HF checkpoints.
model = OpenTSLM.load_pretrained(REPO_ID, device="cuda" if torch.cuda.is_available() else "cpu")
test_dataset = TSQADataset("test", EOS_TOKEN=model.get_eos_token())

test_loader = DataLoader(
   test_dataset,
   shuffle=False,
   batch_size=1,
   collate_fn=lambda batch: extend_time_series_to_match_patch_size_and_aggregate(
      batch, patch_size=PATCH_SIZE
   ),
)

for i, batch in enumerate(test_loader):
   predictions = model.generate(batch, max_new_tokens=200)
   for sample, pred in zip(batch, predictions):
      print("Question:", sample.get("pre_prompt", "N/A"))
      print("Answer:", sample.get("answer", "N/A"))
      print("Output:", pred)
   if i >= 4:
