Error using 'MultiRecord' in batch transform

Hi, I am running batch transform on Sagemaker using BERT model, and my input file is json lines format. If I select ‘MultiRecord’ in ‘batchStrategy’, It gives the following error:

“code”: 400,
“type”: “InternalServerException”,
“message”: Extra data: line 2 column 1 (char 296)"

How could I modify the or input file format or the batch transform code to fix this error? Any suggestion is welcome.

Thanks in advance!


You could use local_mode to develop locally and see what you receive as inputs when working with MultiRecrod.

Here is an example on how you can use local mode for regular endpoints: amazon-sagemaker-local-mode/ at 84b08fd079cb810e0aa6059ecc75bae6f7f3f13d · aws-samples/amazon-sagemaker-local-mode · GitHub
But this should work for batch transform as well → instance_type='local' and local session.

AFAIK you will receive an array of “inputs” as data and not a dict anymore.

Did you manage to solve this issue?
I am experiencing the same problem.
