Creation of Index error

For the last 2 hours I am trying to create an index using the following code:

# Check if the knowledge base index exists
    # Attempt to retrieve information about the index
except pinecone.ApiException as e:
    # If the index does not exist, create it
    if "Index not found" in str(e):
            dimension=len(embeddings[0]),  # Assuming all embeddings have the same dimension

However, it seems to be throwing an error.

This is another variation of the code also generating the same error:

# Check if the knowledge base index exists and create an index if it does not exist
if "demand-writer" not in pinecone.list_indexes():

Now I have used this code last week and there were no errors. Could someone provide some guidance

Can you share more of your code and any other info you have on the error message? For example, can you show how you’re initializing the pinecone client, and can you see what header/value it doesn’t like?


This is the code:

!pip install -qU \
    openai==0.27.7 \
    --upgrade pinecone-client \
    pinecone-datasets=='0.5.0rc11' \

api_key_pinecone = "API_KEY_Pinecone"
env_pinecone = "Environment"
pinecone_index_name = 'pinecode-knowledge-index'

# Function to create metadata based on text_ids
def create_metadata(text_ids):
    return [{"text_id": text_id} for text_id in text_ids]

# Generate embeddings using OpenAI's text-embedding-ada-002

# Extract embeddings from the response

# Create metadata based on text_ids
metadata = create_metadata(text_ids)

# Convert embeddings to DataFrame with text_ids and metadata
data = {'text_id': text_ids, 'embedding': embeddings, 'metadata': metadata}
df = pd.DataFrame(data)

# Specify the filename for the DataFrame
df_filename = "embeddings_dataframe.csv"

path = "/content/gdrive/MyDrive/Colab Notebooks/data/{df_filename}"

# Save DataFrame to a CSV file
df_save_path = f"path"  # Specify the desired path
df.to_csv(df_save_path, index=False)

# Upsert data from DataFrame to Pinecone
index_knowledge_base.upsert(ids=df['text_id'].tolist(), vectors=df['embedding'].tolist(), metadata=df['metadata'].tolist())

print("Embeddings uploaded successfully to Pinecone.")

as for the error:

That error doesn’t match the code you posted as it’s erroring on describe_index but I don’t see describe_index anywhere in the code. (I know you said earlier you get the same error for a different call, but would still be helpful if they match)

I think it would be helpful to see what header it seems to be complaining about. Can you widen your except clause to catch everything, and then log what you’re getting? Or you could debug and put a breakpoint on this line of code:

   1261                 raise ValueError('Invalid header value %r' % (values[i],))
