Is train data read from disk multiple times?

Part 1 (2019)

Hi All,

I’m planning to store my data on a network file system (AWS EFS). Is this a bad idea? I imagine the first time the data is read in it will be slow but is it stored in memory after its read in the first time or is it regularly re-read from disk?

Thanks.

Once I have it setup I may run some performance tests…

It is re-read from the disk every time.
