I'm trying to find an example of Custom Checkpoint Manager in JAVA, that can store checkpoint data in a local folder. Basically, I'm building a java application that reads data from azure event hu...

In my pytorch model, I'm initializing my model and optimizer like this. model = MyModelClass(config, shape, x_tr_mean, x_tr,std) optimizer = optim.SGD(model.parameters(), lr=config.learning_rate)...

I'll run some larger models and want to try intermediate results. Therefore, I try to use checkpoints to save the best model after each epoch. This is my code: model = Sequential() model.add(LST...

We are receiving events from a no. of independent data sources and hence, data arriving into our Flink topology (via Kafka) would be out of order. We are creating 1-min event time windows in our F...

The typical situation in computational sciences is to have a program that runs for several days/weeks/months straight. As hardware/OS failures are inevitable, one typically utilize checkpointing, i...

I have seen in some code examples, that people use .pwf as model file saving format. But in PyTorch documentation .pt and .pth are recommended. I used .pwf and worked fine for small 1->16->16 convo...

I am restoring a stream from a HDFS checkpoint (ConstantInputDSTream for example) but I keep getting SparkException: <X> has not been initialized. Is there something specific I need to do wh...

Goal: Read from Kinesis and store data in to S3 in Parquet format via spark streaming. Situation: Application runs fine initially, running batches of 1hour and the processing time is less than 30 ...

Description We have a Spark Streaming 1.5.2 application in Scala that reads JSON events from a Kinesis Stream, does some transformations/aggregations and writes the results to different S3 prefixe...

What does checkpointing do for Apache Spark, and does it take any hits on RAM or CPU?

In Spark Streaming it is possible (and mandatory if you're going to use stateful operations) to set the StreamingContext to perform checkpoints into a reliable data storage (S3, HDFS, ...) of (AND)...
