OpenAI Authenication Error?

I’m getting the following error when running through the tutorial. Does anyone know I fix this?

AuthenticationError Traceback (most recent call last)
Cell In[36], line 3

----> 3 df[‘embeddings’] = df.text.apply(lambda x: openai.Embedding.create(input=x, engine=‘text-embedding-ada-002’)[‘data’][0][‘embedding’])
4 df.to_csv(‘processed/embeddings.csv’)
5 df.head()

Have you setup your API key in your environment?
