I've successfully trained a LDA model with sagemaker, I've been able to set up an Inference API but it has a limit of how many records I can query at a time.
I need to get predictions for a large file and have been trying to use Batch Transformation however am running against roadblock.
My input date is in application/x-recordio-protobuf content type, code is as follows:
# Initialize the transformer object
transformer =sagemaker.transformer.Transformer(
base_transform_job_name='Batch-Transform',
model_name=model_name,
instance_count=1,
instance_type='ml.c4.xlarge',
output_path=output_location,
max_payload=20,
strategy='MultiRecord'
)
# Start a transform job
transformer.transform(input_location, content_type='application/x-recordio-protobuf',split_type="RecordIO")
# Then wait until the transform job has completed
transformer.wait()
# Fetch validation result
s3_client.download_file(bucket, 'topic_model_batch_transform/output/batch_tansform_part0.pbr.out', 'batch_tansform-result')
with open('batch_tansform-result') as f:
results = f.readlines()
print("Sample transform result: {}".format(results[0]))
I have chunked by input file into 10 files each around 19MB in size. I am attempting at first to run on a single chunk, therefore 19MB in total. I have tried changing strategy, trying SingleRecord. I have also tried different split_types, also trying None and "Line".
I've read the documentation but its not clear what else I should try, also the error messages are very unclear.

The above is the last one I got with the above configuration, before that I was also getting a 400 HTTP error code.
Any help or pointers would be greatly appreciated! Thank you
I managed to resolve the issue, it seemed the maxpayload I was using was too high. I set MaxPayloadInMB=1 and it now runs like a dream
