+# all-MiniLM-L12-v2-qa-en
+This model is an extractive qa model.
+It's a fine-tuned version of [all-MiniLM-L12-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L12-v2) on the following datasets: [squad_v2](https://huggingface.co/datasets/squad_v2), [LLukas22/nq-simplified](https://huggingface.co/datasets/LLukas22/nq-simplified).
+
+
+
+## Usage
+
+You can use the model like this:
+
+```python
+from transformers import pipeline
+
+#Make predictions
+model_name = "LLukas22/all-MiniLM-L12-v2-qa-en"
+nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
+
+QA_input = {
+    "question": "What's my name?",
+    "context": "My name is Clara and I live in Berkeley."
+}
+
+result = nlp(QA_input)
+print(result)
+```
+Alternatively you can load the model and tokenizer on their own:
+```python
+from transformers import AutoModelForQuestionAnswering, AutoTokenizer
+
+#Make predictions
+model_name = "LLukas22/all-MiniLM-L12-v2-qa-en"
+model = AutoModelForQuestionAnswering.from_pretrained(model_name)
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+```
+
