Dear all,

I’m completely a newbie. I would like to configure to use text2vec-palm (Google PaLM instead of open ai, as given in Weaviate’s example). Refer to my code fragments below, I get error when executing in code fragment 3: batch.add\_data\_object…

My CoLaboratory notebook complains that google authentication is missing, suggesting to provide oauth token etc.

I’m stuck at this point. Grateful if someone can shown you sample code that uses text2vec-palm.

Thanks a lot!

# code segment 1 - client config

import weaviate

auth\_config = weaviate.AuthApiKey(api\_key=“MY\_WEAVIATE\_KEY”)

client = weaviate.Client(  
url=“https://my\_weaviate.weaviate.network”,  
auth\_client\_secret=auth\_config,  
additional\_headers = {

```
    "X-Palm-Api-Key": "MY_GOOGLE_PROJ_API_KEY" # Replace with your API key
}

```

)

# code fragment 2 - class def.

# 

class\_obj = {  
“class”: “Question”,

```
"moduleConfig": {
    "vectorizeClassName": "true",
    "text2vec-palm": {"projectId": "MY_GOOGLE_PROJ_ID }, # projectId is required
    "generative-palm": { "projectId": "MY_GOOGLE_PROJ_ID" } # Ensure the `generative-palm` module is used for generative queries, projectId is required
}

```

}

client.schema.create\_class(class\_obj)

# code fragment 3 - add objects

import requests  
import json  
resp = requests.get(‘MY\_DATA.json’)  
data = json.loads(resp.text) # Load data

client.batch.configure(batch\_size=100) # Configure batch  
with client.batch as batch: # Initialize a batch process  
for i, d in enumerate(data): # Batch import data  
print(f"importing question: {i+1}“)  
properties = {  
“answer”: d[“Answer”],  
“question”: d[“Question”],  
“category”: d[“Category”],  
}  
print(f"property: {properties}”)  
batch.add\_data\_object(  
data\_object=properties,  
class\_name=“Question”  
)

Hi!

Can you share here the exact error message you got?

Unfortunately I was not able to get my hands on a palm API yet…

The following error message shows in CoLab notebook when running the batch.add\_data\_object line as in code fragement 3 above. Thanks

{‘error’: [{‘message’: ‘update vector: connection to Google PaLM failed with status: 401 error: Request had invalid authentication credentials.

I’m getting basically the same issue… anyone know how to resolve this?

Hi @elynnstl,

That error is coming from you not passing in the API correctly. Since you want to use a multi-modal model, you’ll have to use VertexAI.

If you go to your Google Cloud dashboard, click on the `Activate Cloud Shell` button (on the upper right). Once the terminal is connected, write `gcloud auth print-access-token` and it should print out a key. You’ll have to refresh the token every hour and the instructions are [here](https://weaviate.io/developers/weaviate/model-providers/google/embeddings-multimodal#vertex-ai).

If you’re using WCD, you will pass it under the `X-Google-Vertex-Api-Key` header. If you deployed it yourself, you can also set `USE_GOOGLE_AUTH=true` and Weaviate will generate the Vertex API key for you.
