I got ValueError: Unexpected member type encountered: blob when executing the model inference in csv format

Run the notebook named example_notebooks/get_started.ipynb and I got the issue for the data type. Is this caused by the library version?

I encountered the same issue today. This alternative code worked for me.

runtime_client = boto3.client('sagemaker-runtime')

sample = test_data.sample(1)
sample_payload = sample.to_csv(header=False, index=False).strip()

response = runtime_client.invoke_endpoint(
    EndpointName=endpoint_name,
    ContentType='text/csv',
    Body=sample_payload
)

result = response['Body'].read().decode('utf-8')
print(result)
