Generate answers for the instructions in a single step:
```python
from distilabel.steps.tasks import EvolInstruct
from distilabel.models import InferenceEndpointsLLM
# Consider this as a placeholder for your actual LLM.
evol_instruct = EvolInstruct(
llm=InferenceEndpointsLLM(
model_id="mistralai/Mistral-7B-Instruct-v0.2",
),
num_evolutions=2,
generate_answers=True,
)
evol_instruct.load()
result = next(evol_instruct.process([{"instruction": "common instruction"}]))
# result
# [
# {
# 'instruction': 'common instruction',
# 'evolved_instruction': 'evolved instruction',
# 'answer': 'answer to the instruction',
# 'model_name': 'model_name'
# }
# ]
