Unable to export Testing and Training data as TFRecord using Google Earth Engine

Question

While trying to export training (about 700 points) and testing data (about 300 points) as TFRecord, I am getting the following error: User memory limit has exceeded

The code I have written, is similar to the material available online, and is:

var band = [ 'B1', 'B2', 'B3','B4','B5','B6','B7', 'B8', 'B9', 'B10', 'B11', 'B12'];
var training = cloudFree.select(band).sampleRegions({
    collection: trainFinal,
    properties: ['CrID'],
    scale: 30,
       tileScale: 16
   });

//Exporting Training and Testing datasets

Export.table.toCloudStorage({
     collection:training,
     description:'Training_Export',
     fileNamePrefix: 'trainingTestData',
     bucket: gcs_bucket,
     fileFormat:'TFRecord'
     });

Is there any mistake in the above code, or should I reduce the number of points / bands?

Answer 1

An out of memory error depends on how much data you're processing. If a lot of data and processing goes into creating cloudFree, you might want to export it as an asset before doing the sampling. That will give you more memory when sampling.
