Describe the problem

Able to use the below command to save spark dataframe to pbr file on s3

myDataFrame.write
    .format("sagemaker")
    .option("labelColumnName", "myLabelColumn")
    .option("featuresColumnName", "myFeaturesColumn")
    .save("s3://my-s3-bucket/my-s3-prefix")

However, when I tried to load the pbr file to create spark dataframe and do some simple processing.

recordIO_df.filter().count()

I got the below error. 

An error occurred while calling o211.save.

Is there any way to create spark dataframe from reading pbr file?

icywang86rui commented 3 years ago

Reading the converted pbr file is not currently supported. Can I ask what is your use case for this?
